Design of NEUE HERBOLD Screw Shredders
The NEUE HERBOLD Screw Shredder plants are equipped with pairs of similarly helicaly srew shafts.
The breaking shafts are stored in a welded trough-shaped housing. For the separation of sand and soil, the housing can be equipped with a sieve bottom.
The breaking of the feeding material works via shear forces both between the screw shafts and the counter teeth in the housing. The slide shafts are equipped with helical screws, this ensures the horizontally transport to the discharge chute. The inlet to the discharge chute can be narrowed to determine the size and amount of the ejected material.
