Primary lump crusher KVB

Primary crushing of lumps

The robust KVB series primary lump crushers are suited to the coarse grinding of agglomerates and lumps which are hard and brittle. Should the product still be too coarse after the primary crusher, we recommend using our MKB lump crusher to grind the coarse goods to the desired final grain size. Thanks to its modular construction the two lump crushers can be built on in a downstream and space-saving manner.

Function

Up until the comb bar the coarse product is milled by rotating beaters and thereafter discharged downwards by means of the changeable comb openings.

Areas of use

In principle all brittle, hard or frozen products with an edge length of up to 150 mm (larger lumps on enquiry) can be milled up to a grain size of 10–15 mm.
