Double-roller crusher R series

Overview
Optimize your crushing process with BEDESCHI crushing solutions: specialist systems designed to handle sticky and moist materials and to start crushing where other systems need cleaning. Using differential roller speeds, material is reduced by a combination of compressive, shear and tensile stresses.

Design features
Each solution is configurable to create tailor-made installations for specific process requirements. Differential speeds between rollers enable controlled material breakage through combined stress modes.

Versatility and advantages
BEDESCHI offers two primary crusher types: the Double Roller Crusher (RI - Normal Duty) and the Sizer (RL - Heavy Duty). Both types can be adapted to application needs and provide effective processing of cohesive materials.

Compact design
BEDESCHI crushing solutions feature a compact footprint compared with other systems of similar capability, offering a space-efficient option for sites with limited installation area.

Suitable for a wide range of materials
BEDESCHI crushers handle a broad spectrum of materials, including highly sticky and moist feeds. Their operating principle reduces clogging and the need for frequent cleaning common with other crusher types.

Performance and energy
Specific energy consumption: From 0.2 to 0.5 kW/t — lower power demand than many alternative machines for comparable applications.

Minimize your fines
Objective: reduce the percentage of fines (0–20 mm). Low roller speed and controlled rotation direction limit fines generation, improving downstream stacking, reclaiming and product quality (critical in cement and aggregate industries).

Operation flexibility
Output particle size is adjustable via the gap between rollers; roller speeds can be tuned within ±10% of the design speed to optimize performance for specific materials.

Maintenance and cost reduction
Units can be mounted on slide rails to move the crusher out of the working position for maintenance. Rollers are fitted with adjustable scrapers for cleaning sticky materials, reducing downtime and wear-part costs.
