KREISEL GmbH & Co. KG products

Slide gates are used as locking, metering and safety components below dosing and in process engineering systems of the bulk material technology. Our slide gate series(engineered at Kreisel) is made for extreme and complicated operating conditions. The specific design of the KREISEL slide gates is based on the system-specific operating conditions and bulk material properties. KREISEL slide gates are designed as knifegate valves with rectangular or rounded crosssection. KREISEL produces a wear-resistant construction from profile steel frame, slidingplate with bearing, sealing system and driveunit. The profile steel frame is designed asflange on the inlet and outlet side. According to the requirements, the sliding plate can be moved by means of actuating drive, pneumatic or hydraulic cylinder, gear motor or hand wheel.

Double flap gates are used to seal vacuum chambers with simultaneous discharging of dust-based and flowing material. KREISEL double flap gates are particularly suitable for discharging of highly abrasive bulk materials at the basic industry as well as the chemical industry: minerals, nature stone, ash, cement, ceramics and coal. The operating principle of the flap gate valve is that two flap gates in a fixed housing open and close alternately. The mechanical system is driven by a gear motor. By means of the gear unit, the reciprocal opening and closing is controlled. In each case, a flap seals the system against false air inflow at diverse pressure ratios, even as the other opened flap is channelled the materials. Drivetrains have been realizing motorized, hydraulically, counterweighted or pneumatically.

The KREISEL DOME VALVE® is an shut-off valve. It is used at high differential pressures up to 16bar. The benefits arise from the cross-sectionbeing available to 100% in the opening condition. It is useable at the pneumatic conveying asa conveying line diverter. In this case there will fitted a Y-pipe with two KREISEL DOME VALVES®. Even so they have been seals against high differential pressures. The field of main application is the pressure vessel conveying. In this case the KREISEL DOME VALVE® work as an running-in and/or running-out valve. The 100% opened cross section protects of bridging and wear because of disruptive elements in the material stream.

If using a pneumatic conveying system either two or more receiving points, such as silos orreactors are feeded, the Conveying line divertercan be used. In addition to the compact design, the crossover is characterized by its low pressure drop. The diverter is designed so that the mainflow direction of the inlet and the outlet is in the same axis. The seal is realized by a valve disk. The structural design ensures that caking cannot lead to blocking of the diverter.

KREISEL two-way distributors are used as control components below (located under) containers, as well as in process engineering systems of the bulk material technology. The design of the KREISEL two-way distributors is based on the system-specific operating conditions and bulk material properties. Depending on the practical requirements of the bulk material flow direction, the distributor can be operated by means of actuating drive, pneumatic or hydraulic cylinder, gear motor or hand wheel. Design size ranged up to cross section 2000mm can be manufactured.

Tubular screw feeders and trough screw feeders are used for high flow rates and also to bridge differences in height. They can be employed in just about any kind of production plant. Screw heat exchangers not only convey the product but also heat/cool it in the process. Screw activators are used to discharge large amounts of bulk material with difficult or poor flow properties. Because several screw spirals are installed next to each other in a housing, the activation effectis excellent. Moisting screw feeders are used for moisting of very fine, dusty and possibly polluting bulk material, e.g. for ash-handling.

The rotating rotor takes up bulk material under the inlet opening and filling his cells. By the rotational movement the bulk material have been conveyed to the outlet. Due to the gravitational force the material fall out at the followed plant area. Thus arised a continuous volumetrically conveying. The output is depend from the volume of the cells and the rotation speed of the rotor.

Selfcleaning-rotary-valves are used to discharge of bulk materials who are bad fluent, humid, pasty and sticky - with constant volume flowrate or to volumetrically dosing out of containers in the following plant. Different design sizes for flow rates up to 750 t/h, are proved in many process plants of different industries. KREISEL selfcleaning rotary valves, manufactured explosion pressure resistant, are certificated for an explosion surge up to 10 bar. Flame arrest manufactured the valves are perfect applicableas a protection system, certificated according ATEX. Selfcleaning rotary valves will customized design accordingly the especially conditions of use. According the special features of the bulkmaterial will customized the wear protection concept.

KREISEL Ceramic Rotary Feeders are the latest state of the art rotary feeders. Their highly wearresistant lining with ceramic elements reduces the wear to conventional rotary feeders by amultiple. Depending on requirement profile different wear protection systems (Wear ProtectA-F) are available. Ceramic places with a Mohshardness of 8.5 - 9.0 (for comparison: Diamond has the highest known hardness of a naturally occurring mineral with Mohs 10) the optimum wear protection. Further advantages are the lateral inspection openings. By the inspection openings the wear condition between rotor sidedisks and housing can be checked in built-instate of the rotary feeder.

KREISEL pneumatic conveying systems are best adepted for conveying every kinds of bulk materials. Conveyor distances over 1,000 meter and conveying rates more than 100 t/h can be realized. Every conveying system will be customised for the special kinds of customer requirements and with an optimum energetic efficiency level. As loading or feed-in componentsare usable: rotary valve, pressure vessel, jet conveyor or screwconveyor comes from the KREISEL manufacturing. The deposit at the point of reception will be realised by KREISEL filtration systems.
