From fine dust with only 0.1 µm grain size up to plastic caps for medical infusions. From the lightest filling agents with only 0.05 kg/m3 up to metal powders with bulk density 10. They are easy to install and operate. Even if leakages occur, no product can get into the environment because of the vacuum. See the variety of materials, with which Vacuum Conveyors can be used in different industries. And this is just a brief overview.Suction out of / from:All Materials can be aspirated directly out of / from produc-tion- and process machines, bins, bags, containers ... Feeding into:The transported material is loaded in cycles from the top into the bin or process machine.Suction Line1765432Operation1. The vacuum pump (1) generates a vacuum in the Vacuum Con-veyors separator tank. Air rushes in through the hose/pipe and the suction inlet (2) from the feeding point (3). The bulk material is aspirated and then carried in this air stream.2. Inside the separator tank a filter module (4) separates air and product. The transported material is kept and collected in the separator. With fine dust a cyclone element (5) inserted into the separator provides higher transportation capacities because of a lower load of the filter elements.3. When the separator is filled with product, the vacuum pump switches off, inside of the vacuum conveyor the pressure is bal-anced to surrounding area within tenths of a second. The sepa-rated material discharges from the vacuum conveyor through the discharge element (6) and falls directly into the unit or tank to be charged (7).4. During discharge of material, the filter module is cleaned auto-matically by an air shock system. The occasional filter cake is released from the filter unit. Volkmann offers piston vibrators and fluidizing units to improve the discharging for sticky or highly bridg-ing bulk materials.5. After unloading the product the discharge element closes and the whole conveying cycle starts again.357911131517192123Aspiration, Transfer and feeding - Volkmann offers maximum benefitHow Vacuum Conveying worksReferencesConveyor types...

The loading ratio of the conveying air is quite small. Depending on the characteristic of the used vacuum generator, flight conveying usually provides the largest transportation capacities. However, sensitive materials should not be conveyed at high speeds to prevent particle abrasion or grain destruction.Dilute phase conveyingIf the air speed w is reduced to a value under 20 m/s, during horizontal or diagonal transportation the conveyed material drops more and more into the lower half of the transportation line. You find more material moving slowly on the bottom of the transportation line while above the bottom sediment a changing number of particles is conveyed at higher speeds. The way the dilute phase conveying occurs is strongly dependent on the products characteristics. In dilute phase conveying you often find areas where plugs can build up (e.g. at the entry of pipe bends) or where regular flight conveying occurs in the top half of the pipes. The material at the bottom of the pipe reduces the transportation lines area and causes a speed increase of the conveying air at certain points. The relationship of the materials speed v to air speed w is smaller than 0.7. The loading inside the transportation line usually is higher than at flight conveying. Vacuum Conveyors, which are adjusted to the dilute phase conveying, offer a very smooth and gentle handling of the material and the energetically most favourable kind of vacuum conveying. Plug conveying (dense phase conveying)If the product load of the transportation air is increased and the air speed reduced, plugs build up inside the conveying line. These plugs build up and disintegrate over the whole conveying length constantly. Therefore reliable working Vacuum Conveying systems can be realized with air speeds w far below the floating speed vS of the single grain (vS is the air speed required to suspend a particle in a vertical suction pipe). Plug conveying usually is the most gentle transportation method for sensitive materials. For plug conveying the vacuum generator should be able to produce high vacuum levels much above those of e.g. blowers. This prevents that the transportation line is blocked . Air speed w lies between 3 and 10 m/s, whereby the ratio of material velocity to transportation air speeds is below 0.5. The product flow-rate can be up to one hundred times larger than the air flow-rate (both in kg/h). Energetically, plug conveying and dilute phase conveying are comparable, since the necessary volumetric air flow is substantially smaller, but the pressure difference rises. The plug conveying is not only applicable with powders and granulates, but also for the transport of viscous or liquid media.The total pressure difference in the transportation line essentially results from the quantity of the material to be conveyed in the line, its flow characteristics, the conveying height and the design of the product loading element and transportation line. The vacuum pump must be able to overcome the total pressure loss inside the conveying line and at the same time to produce the flow rate necessary for the transport of the material (volumetric air flow related to the transportation line cross section). It is important to bring in a sufficiently high measure of additional conveying air into the product (“secondary air”) and/or the transportation line to establish a stable conveying process. By the regulation of this secondary air one can affect the desired condition in the transportation line of a Vacuum Conveying system quite easily, in order to transport e.g. the material particularly carefully to avoid high electrostatic loadings or work against the angel-hair effect at plastics. Inside the transportation line three different conveying conditions can be found:Conditions inside the transportation line57911131517192123HosesPage 19Suction lancesPage 18Product loading systemsPage 18ControlsPage 19Vacuum Conveyor DesignsPages 8-16VOLKMANN – powder-handling unlimited.VOLKMANN Vacuum Conveyors are the preferred choice in Industries, which commit themselves to ...... high hygienic demands for all material transfer equipment... daily/regular cleaning and easy disassembling of all parts with material contact... high efficiency production processes and operational safety... preventing explosion risks and being in control of all processes... state-of-the-art production equipment with outstanding quality and reliabilitymake use of our 25+ years of vacuum conveying experience Suction out of / from:HoppersBig-Bags / FIBCsSilosDrumsBags/LinersKiln sheetsStripsDryersCutting MachinesFloorsMouldsCentrifugesFeeding directly into:Mixers / BlendersReactorsFilling MachinesWeighing HoppersSievesIBCsTablet PressesBig-Bags/FIBCsBag FillersDrumsSilos987654321Volkmann Vacuum ConveyorsOur Focus: Complete solutions 1514121110for Chemical, Pharmaceutical, Food and Pigment applications.are used world-wide.

This conveyor is therefore responsible for the han-dling/loading of the various different powders or granulates, e.g. in chemical process technology or in the color and lacquer industry, where different colors and dyes shall be transported. In such appli-cations the design of the Vacuum Conveyor should permit an easy disassembling and cleaning.At the same time the selected container material must be resistant against cleaning agents and aggressive chemicals. Therefore the stainless-steel modular design was chosen, which guarantees the fast product change on the one hand and on the other hand fulfils the high requirements to the hygiene at chemical-, pharmaceutical and food- processes. Additionally the modular design allows indi-vidual customizations of the conveying system as required. A typical example design of the suction inlet in a radial or tangential design, which can substancially influence the whole conveying process.Tangential suction connections are chosen for reducing the filter load, e.g. if fine powders like TiO2 or toner powder are conveyed. The separating effect of the cyclone can be supported by inserting a funnel (so-called cyclone-insert). With powders with a large particle size distribution however the danger of the separation arising by the centrifugal energy is to be considered. This could be a problem e.g. within chemical-pharmaceutical applications, where substrate and active substance may not separated.In such cases and in cases with adhering/sticky material the radial suction connection is the better choice, since it does not come to a flow over larger areas of the separators interior surface. The material cannot build up on the wall and the mixture remains homogeneous due to turbulences like in a fluid bed. The filter load is larger with the radial suction inlet and must be compensated in some cases by more frequent emptying and cleaning cycles which lowers the suction capacity of the conveyor. The best application-oriented configuration of the Vacuum Conveyor and its modules can be found by suction trials.In connection with our Multijector vacuum pumps particularly small Vacuum Conveying systems are available, which can be used both stationary or mobile. Since high vacuum levels might occur during the plug conveying, our Vacuum Conveyors all are vacuum proof for pressures down to -91 kPa (= 9 m water column).In accordance to the size of the Separator Container, its suction inlet, the chosen filter and vacuum pump a certain transportation capac-ity is reached. The filling volume per suction cycle is constant, the transportation capacity depends strongly on the bulk density and other properties of the conveyed material as well as on the feeding situation of the transportation line.911131517192123Similar to Volkmannwill never be like Volkmann.Ideal technology for each application.

Pressure proof Vacuum Conveyors follow on the next page.Vacuum Conveyors with Inerting function: Volkmann INEX.4321When powders and bulk materials are conveyed or loaded inside explosive and hazardous areas, special aspects have to be considered, as electric discharges caused by the electrostatically charged product are possible:• What are the surrounding conditions at the loading and unloading point?• Does the material itself bear an explosion risk? Is it inflammable?• Is the product easy chargeable?• What happens with the product during the transport and unloading?Special measures can be necessary, if inflammable atmospheres and gases are present in addition to the conveyed material, if the minimum ignition energy (MIE) of the material is below a critical value (usually 1-3 mJ), if exothermal reactions take place or if bigger clouds of dust are generated during the discharge cycles of the conveyor.Volkmann offers best practice solutions for such applications. All new Volkmann Vacuum Conveyors of the VR and PPC series can be regarded “explosion-safe“, if the MIE of the conveyed materials is bigger than 3 mJ (after risk assessment also for materials with MIE > 1 mJ) and if no inflammable gases are present.Additionally, Volkmann offers special Vacuum Conveyors with inerting system for such applications, where solvents or inflammable gas atmospheres occur and need to be considered. These Special Conveyors can even load powders and granulate materials into reactors with a solvent/alcohol atmosphere inside.However, in such critical applications the conveyor is determined by local demands for the conveying task. The many advantages of Vacuum Convey-ors shall be kept to make the work easier and safe, to the benefit of the work force and environment (no contamination or spill, easy and lightweight han-dling, perfect cleaning of all internal surfaces, GMP-conform design...).Only sometimes our „Maximum“-Conveyor in a pressure-proof design is necessary.

For safe operation special terms/conditions apply.II (1) G D (discharging) / II (1) D (2) G (inlet)II 2 G D c Tx Conform to ATEX regulations Under certain conditions, inerting the conveying process can be necessary: A) The material, which is conveyed, has a minimum ignition energy (MIE) < 3 mJ. Under certain conditions the inerting only becomes necessary with MIE < 1 mJ. Talk to us. B) Inflammable gases or liquids are present during the transportation (e.g. suction out of zone 0 or 1; powder alcohol mixtures etc.). C) The material shall be transferred into zone 0 or 1, that means into a zone, in which inflammable gases occur on a regular basis. In the cases A and B the complete vacuum transportation process should be done under inert conditions, since critically high electrostatic charges can occur (caused by the friction between the conveyed product and the suction hose/tube). In the case C) the separator container of the Vacuum Conveyor is inerted in a special step of the conveying process.Important If you want to work without inerting in the cases A-C, a comprehensive risk analysis (usually with instrumentation accompanied conveying tests) is accomplished. We offer special services.All constructions of our current Vacuum Conveyors were revised especially regarding the needs of applications with explosive materials.1517192123Powder locks for Vacuum ConveyorsPowder locks are used for inward transfer of bulk materials into vessels and prevent direct contact between the vacuum conveyor and the vessel to be fed while the discharge cycle. They ensure that no aggressive or hazardous gases or dusts escape through the vacuum conveyor into the surroundings from the vessel to be filled.VOLKMANN powder locks can be inerted easily to prevent gases (e.g. oxygen) to get into the vessel to be filled. Also the opposite direction of gas-flow (from the vessel towards the conveyor) can be eliminated by additional inerting after discharging the lock.Our powder locks can be combined with VR and PPC conveyors as separate modular elements to build a compact and secure vacuum conveyor with parts from only one manufacturer.If necessary, Volkmann powder locks are available optional in 6 bar pressure proof and 10 bar pressure-shock proof design for the filling of reactors under positive pressures.Top: Vacuum Conveyor in pressure-resistant design for the feeding of pharmaceutical substances into reactors.

With special inerting function.Vacuum ConveyorVR450 mounted on a mixer / reactor. With a powder lock(mounted diagonally,as the available space is limited).If products shall be transported by a vacuum conveyor and be transferred directly into areas e.g. like reactors, which withstand positive interior pressure, then the separating container of the Conveyor is designed as a pressure vessel (permissible pressure range: -1 to +6 bar or -1 to +10 bar, different versions according pressure-equipment-directive 97/23/EG available. Container for the connection with standard flanges in diameter 150, 200, 250 and 300 mm available). Also the explosion prevention concept chosen by the operator and individual company-safety-guidelines can make such pressure resistant and/or pressure-shock proof Vacuum Conveyor designs necessary.In a first step, material is sucked into the separator while the pressure-proof discharge element is closed. Next, special pressure proof valves close the suction inlet and close the line towards the Vacuum pump. The filter is cleaned by an air-shock, which can be done with inerting gas. By setting a delay between closing the inlet and shutting off the vacuum pump, the separators volume can be set under vacuum for a further reduction of the Oxygen content. If you give inert gas to the separator for providing the pressure balance to its surrounding, so the whole system can be inerted quite easily. The evacuation of the separator chamber and inerting can be repeated in each cycle for 2-3 times assisting a further Oxygen reduction. Now the pressure balance between the Conveyor and the unit, which shall be fed, is provided. The Conveyors discharge valve opens and the transported material is transferred directly into the unit to be fed. An additional low-pressure back-blow system helps sticky material to fall out the Vacuum conveyors separator container more easily.

For the transportation pipeline special gap-free and shock-minimizing hose systems are used. The tablets enter the conveyor through a deceleration device and are colleted in the separa-tor container. The air is moved-up during the suction cycle whereas possible dusts from the tablets are separated and collected in the filter module. After filling of the glass separator container the vacuum pump is switched off automatically. The tablets are discharged through a pinch valve, e.g. directly into a blister packaging machine or into an integrated glass buffer container. The glass design of the complete conveyor allows a real “transparent” production.The application, the desired conveying capacity but especially the tablets to be conveyed themselves and the kind of loading and dis-charging determine the detail design of the Tablet Conveyor.From us you don’t only get tailor-made conveyors but also complete system solutions e.g. for conveying and weighing of your materials.Talk to us and use our experience in the chemical/pharmaceutical bulk materials handling.VOLKMANN Special Vacuum Conveyors for TabletsVacuum Conveyors with glass-madecontainer system and HEPA filterto fulfil the highest quality demandson the conveyed products surfaceand consistent quality.

The material is given at a high accuracy into a local mixer. Inside the feeding station, the material is fluidised with Nitrogen, to improve its fluidity and lower the risk of ignitions during transportation. The feeding station has almost no residual material inside after the suction process. Operation under completely inert conditions is possible upon request. Options: A partly automated self cleaning system is realizable depending on the transported materials. With toxic and highly effective substances the product contacting surfaces can be wetted completely with water or wash emulsion and can be prepared for more intensive cleaning.

The easy installation, control and free positioning make work more easy. And the workers go for their quiet operation, neither heat emission nor oil mist.But how do you increase efficiency of such a Venturi? How to keep the high vacuum and same energy need but give you lots more of induced air (suction air)? Take a look at the picture of the MULTIJECTOR® to understand: A classical Venturi comes with a primary nozzle (injector), a secondary nozzle (diffuser) and a jet chamber (the gap between). The compressed air rushes through the primary nozzle, expands and accelerates, which causes a pressure drop. On its way towards the secondary nozzle it catches and mixes surrounding air and finally exits the Venturi through the secondary nozzle.... to the MULTIJECTOR®A MULTIJECTOR® comes with an advanced nozzle system, in which additional nozzles are placed in line with the primary and secondary nozzle. The suction air of each venturi stage mixed with the compressed air of the primary nozzle works as the gas jet for the following stage. For free and with no more air consumption. These additional Venturi stages don’t reach the high vacuum of the first, but their larger jet chambers produce an even higher suction volume. Still the vacuum pump reaches the high vacuum of the first Venturi stage, because flap valves close automatically in order of pressure balance between their certain Venturi stage and the collective vacuum chamber.The special design of nozzles and aerodynamics gives Volkmann MULTIJECTOR vacuum pumps their unique efficiency: Common single stage Venturis perform at a ratio of 0.7:1 (suction air : needed compressed air). Modern Multijectors reach a ratio of up to 6:1. Take a MULTIJECTOR and save compressed air.Energy consumption only in thesuction cycle of the conveyorIn a vacuum conveyor the Multijector is turned on only during the suction cycle. While discharging the separator, the Multijector can easily be switched off. It requires no starting time for the next cycle like electrical pumps, also it has no wear during start and stop. The Multijector saves about 1/3 of compressed air during discharging, while electrical pumps need to run continuously and require additional vacuum valves to shut off the vacuum conveyor during discharging.Electrical vacuum pumpsCustomers ask for electrical pumps rarely, we have to admit. Because of many cost saving advantages which our Multijectors offer especially for vacuum conveying. However, sometimes we suggest to use an electrical vacuum pump with our conveyors – e.g. if the compressed air supply on site is insufficient or at very long conveying distances. But you can be sure: we always do our best to find the optimum solution for your conveying application and consider your special demands and requirements.2123Multijector pumps of the M-series work with three ejector stages which are connected in a row. Their robust and compact aluminium casing makes the pump resistant even to strong mechanical loads. Nevertheless they are very light and offer considerable amounts of suction air at a small size. M-Types are used with Volkmann Vacuum Conveyors in the diameter 170 mm.Our G-type Multijectors are four-stage ejectors and offer an even better efficiency especially at free aspiration and low vacuum. They consist of a light and nevertheless tough modular Aluminium design. They are the ideal choice for bigger transportation capaci-ties. G-types are used for Vacuum Conveyors with diameter 250 mm and bigger. They are available with silencer or exhaust adaptor element.General dataoperating pressure:4 to 6 bar flow pressure(optimum 5.6 bar)operating noise:55 to 78 dB(A)Operation temperature:-20 to +80 °CMaterials:Al, PE-HD, NBRMultijector Operat.

Some characteristics of the material help us to make a first estimate of the correct size of unit.Then the required type of product loading and unloading are set. Is manual suction with suction lances desired e.g. from barrels or bags? Or is it necessary to do the material feeding automatically, e.g. from silos, Big Bags or process machinery? How about the control system necessary? And how is the Conveyor to be connected to the unit which shall be loaded with the material? Mounted above without connection, flexible connection pipe or permanently fixed to it? Further characteristics of the material as well as the surrounding conditions determine the exact design of a Vacuum Conveying system: How good is the pourability of the conveyed product? Is the material extremely fine? Does it have to be loosened up and/or fluidized to prevent bridging, in order to flow and be conveyable? Is the product sensitive to humidity/moisture? Can it block in the transportation line? Is there a risk, that material properties change by transport, e.g. the grain size is reduced by grinding effects between the particles and the transportation system? Is there the risk of segregation of the material? Does the surface of the product have to be protected by special measures, in order to avoid scratches and other impairments on the product itself?Aspects of health protection, explosion prevention and environ-mental protection play a further important role, in order to be able to offer safe working Vacuum Conveying equipment. Is the material harmful or toxic? How may one come in contact with the product? Can it cause allergic reactions? Which filter quality is necessary? Are there risks for the environment? Can the exhaust air of the Conveyor go back directly into the room or is a central exhaust air system necessary and present? Is the material explosive, can it be ignited? Are ignitable gases present or can these be emitted from the product itself? Which conditions are present at the product loading point and the unloading position? What is inside the unit to be fed? Are explosion zones defined?The reverse case can be found regularly e.g. in pharmaceutical production: there the product is protected against the environment. Which materials may come in contact with the product which is conveyed? Are special material certificates necessary e.g. for a qualification/validation of the production process? We supply according to your requirements.Inside your project we will work together and evaluate all these questions – we don‘t want you to buy a Vacuum Conveyor just based on catalogue data. We want you to work satisfied with a really safe and reliable Vacuum Conveying system which helps you to produce efficiently and profitably and that you eliminate unnecessary risks inside your production works.
