The main difference is the focus on size reduction. A lump breaker is an economical, high-capacity solution for basic de-lumping (breaking up large chunks). A screen mill (or hammer mill) provides more precise, continuous sizing for fine or consistent final particle output.

Yes, Noggrann offers lump breakers for both washdown and explosion-proof environments. We supply optional designs in 304 or 316 stainless steel construction for sanitary washdown and explosion-proof (ATEX-compliant) components for hazardous dusts.

Yes, the Hapman LumpMaster® is available in three standard sizes: 12 inches (30.5 cm), 18 inches (45.7 cm), and 24 inches (60.9 cm). The correct size depends on your flow rate and the maximum size of the lumps being processed.

Lump breakers can handle many materials, including caked powders, dried chemicals, compacted granules, sugar, salt, and various mineral products that tend to harden or clump during storage.

Noggrann units break down compacted material using a low-speed, high-torque design with robust metal claws or blades. This provides the necessary force to shear through large, compacted lumps without generating excessive fines or dust

A lump breaker (or de-lumper) is a simple, heavy-duty machine used to reduce compacted and agglomerated bulk materials into smaller, conveyable dimensions. It should be used inline before downstream equipment, such as a conveyor or feeder, to ensure smooth, clog-free material flow.
