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.
What is a rotary breaker?
A rotary breaker is a type of size reduction equipment that uses one or more rotating elements — rotors, blades, or impacting fingers — to break down oversized lumps of bulk material. Jersey Crusher's rotary lump breakers include counter-rotating dual rotor models (Lump Busters®) and single large-diameter rotor models (Lump Abradors), each suited to different material types and processing requirements.
What is a delumper?
A delumper is another term for a lump breaker or de-agglomerator — a machine that breaks up clumped, hardened, or agglomerated bulk materials back into a free-flowing state. Delumpers are widely used in chemical, food, pharmaceutical, and fertilizer processing. Jersey Crusher's Lump Busters® and Lump Abradors serve this function with precise, controlled particle size reduction.
What materials can Jersey Crusher's rotary lump breakers process?
Jersey Crusher's rotary lump breakers handle a wide range of friable materials including sugar, salt, spices, chocolate, fertilizers, chemicals, pharmaceuticals, plastics, coal, clay, foundry sand, cannabis biomass, and more. Both shearing-action (Lump Busters®) and abrasion-action (Lump Abradors) models are available to match specific material properties and downstream process requirements.
What construction materials are available for rotary lump breakers?
Jersey Crusher offers lump breakers in 316 Sanitary Stainless Steel (for food, pharma, and cosmetics applications), 304 Stainless Steel (general industrial), Carbon Steel with blue enamel finish, and Abrasion-Resistant material variants for aggressive bulk solids. Sanitary units include optional food-grade white epoxy interior finish and baseplates in stainless steel.
Can I get a custom screen size or configuration for my application?
Yes. Jersey Crusher's rotary lump breakers feature customizable integrated size reduction screens or breaker bars with hole diameters from ⅛ inch to 2 inches and beyond. Screen configurations are engineered to customer-specific particle size targets. A free product sample test and evaluation service is available — ship your material to Jersey Crusher's engineering team for analysis and solution design.
Are Jersey Crusher's lump breakers suitable for pharmaceutical and food-grade applications?
Yes. Jersey Crusher's 316 Stainless Steel sanitary models are designed for FDA-adjacent, GMP-aligned, and USDA-compatible production environments. Key food and pharma features include air purge shaft seals to prevent cross-contamination, tool-free screen and comb changes on sanitary Lump Abrador units, optional food-grade white epoxy interior finish, and material traceability documentation available upon request.
