Four Roller Crusher
Introduction
Four Roller Crusher as a high-efficiency crushing equipment integrating medium and fine crushing functions, it features a unique four-roller design that adapts to the crushing requirements of various industries and materials. With its core advantages of low energy consumption, stable operation, and strong wear resistance, it has become the preferred crushing solution for mining, coal, building materials, and other fields.
Four Roller Crusher
Integrated two stage crushing completely solves clogging issues. It delivers stable performance for industrial medium and fine crushing operations, boasting wear resistance, high efficiency, and user-friendly operation.
Application
Four Roller Crusher widely applied in mining, coal, building materials, metallurgy, chemical engineering, environmental protection, and other industries, our Four Roll Crusher can crush various solid materials with a compressive strength of ≤300MPa, including iron ore, quartz stone, limestone, river pebbles, coal gangue, cement clinker, construction waste, gypsum, and bentonite. It perfectly meets the diverse needs of medium and fine crushing operations.
Mining Industry: Processes sinter return ore, iron ore tailings, and other materials, ensuring uniform feed size for grinding and improving ball mill efficiency;
Coal Industry: Crushes raw coal, coke, and wet coal gangue, enabling normal production even in rainy seasons without clogging issues;
Building Materials Industry: Crushes limestone, clinker, and construction waste, realizing multi-purpose operation with one machine and simplifying the production process;
Chemical Industry: Processes chemical fertilizers, chemical raw materials, etc., with uniform crushing effect to meet subsequent processing requirements.
Core Advantages
1. Two-Stage Crushing, One-Time Forming
The upper and lower roller groups have clear division of labor—the upper rollers for coarse crushing and the lower rollers for fine crushing. No additional screening or material return equipment is required. The feeding size is ≤200mm, and the discharging size is adjustable from 0.01mm to 10mm.
2. Anti-Clogging & Strong Adaptability
The screen-less design fundamentally eliminates clogging caused by wet and viscous materials, capable of handling materials with moisture content ≤30%. Roller surface adopts high-chromium manganese steel alloy for excellent wear resistance.
3. Low Consumption & Stable Operation
Low-speed extrusion method consumes less power and generates low noise. Equipped with a spring or hydraulic automatic retreat device to avoid unbreakable objects, ensuring continuous long-term operation.
4. Flexible Customization
Roller surfaces can be combined with toothed, surfacing, or flat rollers. Transmission options include V-belt or coupling. Diesel or gasoline engine drive is available for power-free scenarios.
Working Principle
The Four-Roll Crusher achieves graded crushing of materials by utilizing the extrusion force and shear force generated by the relative rotation of four high-strength wear-resistant crushing rollers.
Materials enter the V-shaped crushing chamber formed by the upper two rollers for coarse crushing through extrusion and shearing. The coarsely crushed materials fall naturally into the lower two-roller crushing chamber, where they are further extruded, sheared, and ground. Finally, the materials are discharged in the required particle size. The entire process is continuous and efficient.
