Some Basic Information of Double Roller Crusher
PG Double roller crusher is mainly used to crush material which is below the medium hardness, such as clinker mineral, coke, slag, shale, limestone and so on. It is the most suitable for small and medium non-metal mines and chemical industries to undergo secondary and fine crushing. It has the following features: simple structure, reliable performance, less flour.
The Main Features of Double Roller Crusher
1. Adaptable and flexible application
2. the use of wear-resistant materials,more durable
3. High production and high crushing efficiency
4. Equipped with dustproof and silencing device, zero dust and zero noise.
The Working Principle of Double Roller Crusher
The adjustment of discharging granularity: There is a wedge-shaped or gasket adjustment device between the two rolls, and on the top of the wedge-shaped device, there is an adjusting bolt. When the adjusting bolt pulls up the wedge, the wedge will lift the movable roll from the fixed roll, so that the gap between the two rolls will become large, and the discharging granularity will become large. When the wedge goes down, under effect of the pressure spring, the gap between the two rolls will become small, and the discharging granularity will become small. The gasket device adjusts the discharging granularity through increasing and decreasing the number or thickness of the gasket, and when the number of the gasket increases, the gap between the two rolls will become large and the discharging granularity will become large; when the number of the gasket decreases, the gap between the two rolls will become large and the discharging granularity will become small.
