Roller crusher is suitable for the coarse and medium crushing of crisp bulk materials in cement, chemistry, power, mine, metallurgy, building material, refractory and coal mines. The feeding granularity of this machine is big and the discharging granularity is adjustable. When using this machine to crush raw coal in coal industry, after deironing and edulcoration without gangue removing, the raw coal can be directly crushed, and the crushed materials have even granularity and low over crushing rate.

So now to optimize the performance of roll crusher is particularly important, we need roller crusher to have a stable performance and reduce energy consumption as far as possible, realizing energy conservation and emissions reduction of roll crusher. Therefore now there are a lot of mining machinery enterprises who are actively researching how to improve the performance of the roller crusher, hoping that could lead to the product upgradation and the obvious energy saving effects of roll crusher. So every crushing equipment manufacturer is striving to produce the roll crusher with smaller size and noise generated, bigger reduction rate and less energy consumption.

The sandstone production line in many places has a very simple process, while the wide application of roll crusher brings customers unexpected benefits. But many of the current roll crusher is rather traditional: unstable performance and large energy consumption, making the final sand aggregate have a high over-crushing rate.
