Lump Breakers & Crushers for Bulk Materials

Lump breakers and crushers such as Jersey Crusher's Lump Busters® are commonly used to crush coal and mineral feedstock. Their counter-rotating dual rotor design with customizable screen configurations handles friable materials like coal, clay, lime, and ore samples. Available in carbon steel and abrasion-resistant material variants suited for mineral and mining applications.

A lump breaker is designed for gentle size reduction of friable, agglomerated, or compacted bulk solids without heavy pounding — preserving product integrity. A crusher typically implies more aggressive mechanical force. Jersey Crusher's Lump Busters® use shearing action, while Lump Abradors use abrasion — both engineered to minimize fines and dust compared to hammer mills or pin mills.

Jersey Crusher's lump breakers process a wide range of bulk materials including sugar, salt, chemicals, fertilizers, coal, clay, pharmaceuticals, spices, chocolate, frozen foods, thermoplastic resins, pigments, detergent powders, animal feed, foundry sand, and more. Both carbon steel and sanitary stainless steel models are available to match the specific material and regulatory requirements of your application.

Jersey Crusher's lump breakers deliver particle size outputs ranging from coarse reduction up to 2 inches down to fine reduction of ¼ inch or smaller. Screen hole diameters are customizable from ⅛ inch to 2 inches and beyond. Adjustable rotor speeds between 300 and 1800 RPM provide additional control over final particle size distribution for diverse material types.
