General natural stones are big, so they are not suitable for construction building in the first place. We must crush these stones into small size or change the form of it by stone crushing machine. Stone crushers are the machine that is used to reduce the size, or change the form of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different compositions can be differentiated.

Large stone materials are evenly fed into the jaw crusher by vibrating feeder for the primary crushing process, once that the materials are conveyed to the impact crusher by belt conveyor for fine crushing. Then, the crushed materials are conveyed to the vibrating screen for screening and grading. The particles that meet the required size demand are sent to the finished product stockpile, and people do not satisfy the dimensions demand are sent to the impact crusher for sale to be crushed once more. This process will continue until the final particles satisfy the size requirement.

Our company has achieved a lot in the energy conservation aspect of the roller crusher. The roller crusher manufactured by our company is not only small in the size, high in the crushing ratio and low in the production noises, but the energy consumption is reduced by 30%, and the sand and stone aggregates produced by this machine are even in granularity. The crushing mechanism of smooth roll crusher is mainly is squashing, and the crushing mechanism tooth surface roll crusher mainly is breaking, the two both have the function of grinding machine china. The former is suitable for the fine crushing of medium hardness ore and the latter applies to the coarse and medium crushing of brittleness and loose ore.
