Lump primary crusher

precrushing of agglomerates and 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.
