On a centrifugal sifter, the bulk material is fed in a controlled flow into the cylindrical basket containing the sieve house. Fast rotating blades push the product against the sieve and transport the oversize particles in a axial movement towards the oversize outlet.
Many raw materials tend to create lumps during transporation and storage. The product loses his ability to be processed easily. Pneumatic conveying systems may get disturbed, feeder deliver inaccurate recipes, and mixers cannot distribute the ingredients to a homogene concentration in the mixing chamber.
The quality and concentration of ingredients and active substances are increasing. This generates the need for reliable feeders for the lowest capacity range. The constant federate and the accuracy should be developed to the maximum.
Quick disassembling of equipment is desired to reduce the cleaning time, for better inspection and offers an advantage for frequent product change. Gericke is completing its proven feeder product range with the new GDU 151, which doses in the range of 0.05 - 600 l/h.
