Frequently Asked Questions

What is a lump breaker?

A lump breaker is an industrial size reduction machine designed to break apart agglomerated, caked, or compacted bulk solid materials into a uniform, free-flowing particle size. Unlike crushers or mills, lump breakers use controlled mechanical action — such as rotating blades, fingers, or counter-rotating rotors — to reduce friable material without generating excessive dust or fines.
