Mahr GmbH products

The cast iron slide valve Type GFS is used in silo and tank outlets. It guarantees optimum sealing when storing bulk materials containing dust or in granulate form.

The flat slide valve is used as emergency slide valve at silo and tank outlets to be able to perform maintenance work on downstream discharge elements without emptying the silo. It guarantees optimum sealing when storing bulk materials containing dust or in granulate form up to maximum 4 mm grain size.

The MAHR special tube valve SP P is used in high pressure conveying systems as closing element for delivery lines. It is mainly installed at the outlet of the delivery line from the pressure conveyor.

The pressure vessel has established itself for pneumatic conveying with high pressures (long conveying distances) and high product concentrations (high delivery rates). In the case of poorly flowing products, it is possible to increase the flowability using additional measures (cone venting, mechanical discharge aids). Depending on the conveyed material and conveying distance, gravity draining (connection of the delivery line underneath the discharge funnel) or cover emptying (connection of the delivery line from above vertically into the protruding pressure vessel riser pipe) and various ratios of the upper, lower and secondary air supply. The pressure vessel can be loaded either in free fall or using suitable mechanical feeders.

The tube switch is mainly used in delivery lines of high pressure systems; however it can also be used in the low pressure range at any time. It is suitable for the transport of dry, non-adhesive or tending to cake dusts and is used for changing the direction of the delivery flow.

Silos are used for the storage of all types of bulk materials over a long time. The variable composition of various sizes for a complete silo system in a confined space enables maximum storage capacity. This concept is ideal for use at terminals due to the use of powerful filling and emptying systems.

Pneumatic conveyor systems are currently used in many areas of the bulk materials processing industry. The bulk materials for conveying range from dust-like (Ø = 0 - 0.5 mm) to coarse-grained solids (Ø > 10 mm). The conveying capacities are a few kilograms up to several hundred tons per hour. The diameters of the conveying pipeline vary here from less than 50 mm to more than 500 mm. Conveying distances up to 1000 m can be bridged.

The calcium mixture preparations from Mahr GmbH are designed for dry, finely powdered lime [Ca(OH)2]. All components are matched with each other for sufficient storage of lime, the required dosing quantity and accuracy and the required lime milk quantity.

Design: The boiler consists of the dished bottom, the cylindrical jacket and the cone with the taper angle of 60°. Every tank has a manhole and all spouts for the necessary valves. The position of the spots is variable. The spout position depends on the local conditions.
