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 gear transmission device of the roll crusher mainly consists of fixed roller, dynamic roller, transmission shaft, main engine, chassis, covering shell and long gear covering shell. The roller crusher is powered by the V-belt pulley on the motor, and through a couple of middle reducers, it drives the fixed roller to spin and relying on the couple of long gear pulley installed on the other end of the fixed roller, the dynamic roller is driven. The two rollers are moving towards each other for squeezing materials.
Roller crusher is made up of fixed roll, movable roll, drive shaft, body, chassis, shell, long gear housing, and the main working features of this machine are including the follows.
1. Lower noise and reliable operation
Roller crusher owns the strong production strength, and the performance characteristics are stable and reliable while lowering the noise pollution, so it can make a difference to the environment protection.
2. Higher production efficiency, bigger processing capacity
The finished products are cubic shape, and the percentage of those needle-like finished products is lower while there is no internal cracking. The discharging granularity is fine, so it can improve the production quality and efficiency.
3. Long lifespan of those wearing parts and ess consumption
The usage circle of the roller is long, and the wearing parts are taking the latest refractory, so it can crush the tough-hardness materials with lower consumption, which certainly can bring much more economic profit for our customers.
Roller crusher is one equipment that being used for the coarse and fine crushing process, and this machine is widely used in metallurgy, building materials, refractory and so on
Adjustment of the discharging materials: wedge-shaped or gasket adjustment device is installed between the two rollers; adjusting bolt is installed on top of the wedge-shaped device, and when the wedge is pulled up by the adjusting bolt, it will push the dynamic roller pulley away from the fixed pulley, thus making space between the rollers wider and particle size bigger; when the wedge moves down, the dynamic roller pulley is pressed by the hold-down spring and then the space gets smaller as well as the particle size. The gasket device works depending on the adjustment of the number and the thickness of gaskets. When adding more gaskets, space between rollers and the particle size will become big; vice versa.
