Frequently Asked Questions
What are the three types of crushers?
The three primary types of industrial crushers are jaw crushers, which use compressive force between two plates; impact crushers, which use high-speed rotors to strike material; and roll crushers (including dual rotor lump breakers), which use counter-rotating shafts or rollers to shear and break friable materials into controlled particle sizes without heavy pounding.
What is a double roll crusher?
A double roll crusher — also called a dual rotor crusher or lump breaker — uses two counter-rotating shafts fitted with intermeshing teeth or finger-pattern rotors to shear and compress material between them. Jersey Crusher's Aurora Lump Breaker design applies this principle to break friable agglomerates gently and precisely, producing consistent particle sizes without dust-generating hammer impacts.
What materials can the Aurora Dual Rotor Crusher process?
The Aurora Lump Breaker handles a broad range of friable materials including sugar, salt, spices, chocolate, frozen foods, chemical cake, agglomerated powders, fertilizers, coal, clay, ore, animal feed, pharmaceutical intermediates, foundry sand, and compacted plastics regrind — across food, pharma, chemical, mining, and agricultural applications.
What particle size output can I achieve with a dual rotor lump breaker?
Jersey Crusher's integrated screens and breaker bars are customizable with hole diameters from ⅛ inch up to 2 inches and beyond, enabling output from coarse reduction (up to 2 inch) down to fine reduction (as small as ¼ inch). Rotor speed adjustments between 300 and 1800 RPM provide further control over final particle size distribution.
What construction materials are available for the Aurora Lump Breaker?
Models are available in carbon steel with blue enamel finish, 304 stainless steel for general industrial use, and 316 sanitary stainless steel for food-grade, pharmaceutical, and GMP-aligned applications. Abrasion-resistant material variants are also offered for aggressive or highly abrasive bulk solid processing environments.
Is the Aurora Lump Breaker suitable for food and pharmaceutical applications?
Yes. The 316 sanitary stainless steel models are designed for food-grade and GMP-aligned pharmaceutical operations, featuring an optional food-grade white epoxy interior finish, air purge shaft seals to prevent cross-contamination, easy clean-out access, and material traceability documentation available upon request for regulated industry audits.
How do I determine the right model size for my application?
Jersey Crusher offers a free product sample test and evaluation service. Ship your material sample freight-prepaid to their Wayne, NJ facility, and their engineering team will analyze it to recommend the optimal model size, rotor configuration, screen specification, and material grade. Contact 862-356-6112 for sample shipping details or call 973-686-5999 for a consultation.
