The double roll crusher has several different names, such as roll crusher, double roll crusher, double roll crusher and double toothed roll crusher. The double roll crusher is a machine that uses the friction of the roll surface to bite the material into the crushing area and make it bear the crushing or splitting. When it is used for coarse crushing or needs to increase the crushing ratio, teeth or grooves are often made on the roll surface to increase the splitting effect.
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 dust-proof 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.
It is widely used in cement clinker, sand making, building materials, mining, chemical industry, steel cement clinker and other industries. The hydraulic roller crusher is a kind of machine which is extended by the spring roller crusher. The advantage of hydraulic structure is that it can control the pressure between two rollers 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 pity to the production capacity of the grinding equipment.Generally the output can be increased 30%-40% and the energy consumption can be reduced by 20%-30%.
