Lump Breakers

What is a Lump Breaker?

Lump breaker machines, also referred to as lump crushing equipment, are size reduction machines that crush materials with their state-of-the-art blades. Lump crushing equipment is able to reduce lumps created in the production, storage or transportation of bulk solids and powders - without generating excessive dust and fines. The rotation of specially shaped blades through a fixed comb gives an efficient lump breaking action.
