Our pre-breakers / lump breakers are designed to work in conjunction with our other mills or as stand alone coarse grinding mills in their own right. Robustly designed for reliability during even the most arduous of duties, they are capable of breaking down large lumps of product, up to 150 mm dia. and reducing them to 2 - 3mm in preparation for further processing.


All models available in carbon steel or stainless steel 304L or 316L.

Special alloys available on request e.g. Hastelloy
