What is Large Double Roll Crusher

The large double roller crusher is a kind of machine which is extended by the hydraulic roller crusher. The advantage of hydraulic structure is that it can control the pressure between two reliefs accurately. Long-term continuous operation can still guarantee the crushing pressure between two rollers. Therefore, the equipment of roller crusher in the grinding system can give full play to the production capacity of the grinding equipment. Generally, the output can be increased by 30%~40%, and the total energy consumption can be reduced by 20%-30%.

The roller skin of this machine is made of our company’s patented material, which is the advanced wear-resistant material in China. Continuous service life can reach more than one year. Small amount of maintenance, low cost, which is no other domestic crusher comparable.
With compact structure, light weight and small volume, the equipment of roller crusher can significantly save investment for the crushing powder grinding system with the same production capacity requirements.
Simple structure, small space, convenient operation and maintenance.
Reasonable structure, low operation cost, stable operation, high efficiency and energy saving, high crushing efficiency and adjustable discharge particle size.
The interior is equipped with dustproof board with good sealing performance, which avoids the splash of small materials after crushing, with less dust and low working noise, and greatly improves the working environment.
The machine is equipped with safety protective device. When unexpected metal iron parts enter the crushing cavity, the protective device moves and the iron parts leak out and the equipment runs normally.
The machine’ s gap between two rollers can be adjusted freely between 1mm-20mm. After the roller’ s gap is adjusted according to the requirements of crushing grain size, the crushing grain size can be controlled reliably, and all of it is discharged from the lower part of the crushing chamber with ideal grain size.
