This equipment is a combination of a silo unloader with a flexible screw conveyor. Whatever the silo capacity the silo discharge unit DDS 400/DM guarantees flow control and accurate feeding of your powder product such as quick lime, hydrated lime, powdered activated carbon, etc.

In order to increase the accuracy of the volumetric feeder, the equipment can be equipped with an electronical device to become a loss in weight gravimetric feeder.
The arch breaker or silo unloader is fitted with a slide gate valve assembly and is totally mechanical. The product is always maintained within the feeder which guarantees feed accuracy independently of the load in the silo. The silo unloader can be mounted on new or existing silos. The conveyor ensures that the product is transferred to the process application. One silo can be fitted with several screw feeders either flexible or rigid.

Various Sodimate equipment can be fitted at the outlet of the screw feeder, such as Conveying screw DMR, Injector ID, Mixer MBV, Mixing tank…

By installing a silo arch breaker ZCD 800, it is then possible to install up to 4 screw feeders with different outputs. This is an effective solution for gas treatment systems where several incineration lines need to be fed.
