Heavy-Duty Double Roll Crusher & Wear-Resistant Tooth Plates
The Double Roll Crusher manufactured by Henan Centbro Machinery Equipment Co., Ltd. (STM Machinery) is a high-efficiency secondary and tertiary crushing machine designed for processing coal, coke, limestone, clay, iron ore, and abrasive minerals.
Engineered with heavy-duty forged rollers, precision gap adjustment mechanisms, and high-wear-resistant alloy roller shells, our crushers deliver high reduction ratios, low power consumption, and minimal over-crushing across diverse industrial applications.
Double Roll Crusher Working Principle & Design Types
Understanding the double roll crusher working principle is essential for optimizing plant performance. The machine utilizes two counter-rotating rollers to crush material via high-pressure compression and shear forces:
- Toothed Roll Crusher: Designed with specialized tooth profiles (e.g., 50-series teeth segments) that shear and fracture sticky, medium-hard materials like coal, clay, and shale without clogging.
- Smooth Roll Crusher: Features smooth roller surfaces engineered to crush hard, friable minerals down to fine, uniform particle sizes with high crushing force.
- Hydraulic Double Roll Crusher: Equipped with advanced hydraulic safety cylinders that provide continuous roll gap pressure adjustment and automatic tramp iron release to prevent roller damage.
Technical Performance & Spare Parts Engineering
1. Superior Roller Shell & Tooth Plate Wear Resistance
Roller shells and teeth plates endure constant impact and abrasion. STM Machinery manufactures double roll crusher teeth / roller shell spare parts using premium high-manganese steel (Mn13Cr2, Mn18Cr2), high-chromium alloy, and composite wear materials. Our proprietary heat-treatment process increases component wear life by up to 30%, significantly reducing downtime and maintenance costs.
2. High Capacity & Uniform Particle Size Output
Precise roll gap settings prevent material over-grinding, ensuring high throughput and uniform output particle distribution. For precise plant sizing, our engineering team assists clients with double roll crusher capacity calculation based on roll diameter, speed, gap width, and raw material bulk density.
3. Reduced Operating & Energy Costs
Direct-gear or belt-driven transmission systems maximize energy efficiency, cutting kilowatt consumption per ton of processed material compared to traditional impact or hammer crushers.
