Product Overview
This Double Roller Crusher is professionally designed for coal, coke and coal gangue crushing scenarios. Different from ordinary crushers that produce excessive fine powder, this machine adopts optimized roller extrusion structure to achieve extremely low over-crushing rate. It precisely crushes bulk coal and coke into uniform granular products while minimizing fine powder generation, effectively improving material utilization rate and commercial value. It is ideal dedicated crushing equipment for coal preparation plants, coke processing plants and coal aggregate production lines.
Key Features
Ultra-low over-crushing rate: Specially optimized gap and roller tooth layout avoids excessive grinding of coal and coke materials, greatly reducing fine powder and waste. The finished coal and coke granules keep complete particle shape and high market competitiveness. Stable extrusion crushing replaces violent impact crushing, protecting original material texture and improving qualified particle yield.
Smooth feeding and anti-blocking design adapts to bulk coal and sticky coal working conditions. Flexible roller gap adjustment allows free switching of particle sizes for coal lump, coal grain and coke aggregate. The whole machine runs steadily with low noise, low energy consumption and low failure rate. Simple structure brings convenient daily maintenance, perfectly matching long-time continuous operation of coal processing plants.
Working Principle
Under stable power drive, the two rollers rotate inward synchronously. Large coal and coke blocks are evenly fed into the crushing cavity. Through gentle and uniform extrusion and shearing force between the rollers, bulk materials are broken into target granular size. Without high-speed impact grinding, it effectively controls over-crushing phenomenon. Users adjust roller clearance to precisely control finished particle grade, ensuring stable and high-quality coal and coke output.
Applicable Materials
Mainly suitable for coal, coke, coal gangue, charcoal and other brittle fuel materials. It performs best in processing materials that require strict control of fine powder and complete particle integrity.
Application Scope
Widely used in coal mines, coal washing plants, coke factories, thermal power plants, coal material processing yards and fuel aggregate production lines. It is specially used for medium and fine crushing of coal and coke to produce standard fuel particles and industrial raw materials.
