The main structure of roller crusher is a pair of cylindrical rollers which install on the main rack horizontally. As we all know, roller crusher is widely used in industries like cement, mining and quarry stone, etc. Roller crusher is usually used in the fine crushing for kinds of ores and rocks with high or medium hardness such as ore beneficiation, chemistry, cement, fireproof materials and construction materials. It has superior performance than other crushers especially for artificial sand and stone in construction materials.

The roller crusher is a kind of traditional crushing equipment which has simple structure and high efficiency. The main structure of this crusher is the crushing roller which is composed of axis, wheel hub and roller skin. The most important part is the roller skin because its abrasion will influence the working efficiency of the whole roller crusher greatly.

For roller crusher, it should pay special attention to the protection and maintenance of the spare parts and the whole machine.

1.It should strengthen the deironing work because the non crushing items which enter the roller will damage the crusher. So it should install the deironing device before operation.

2.It should reinforce the check of roller crushing equipment and add lubrication oil to the equipment so as to keep a good and stable condition. In addition, it should check the abrasion of the spare parts and change the spare parts if needed.

3.After long time operation, the abrasion on the roller skin will lead to the ultrafine granularity, so it should check and adjust the discharging mine mouth.

4.To make the chassis flat surface movable and remove the dust lest that the movable bearing can move on the chassis when there is some materials that can not be crushed so that there may be serious accident.

The roller crusher is a new product by absorbing advanced technology and different requirements so that it has higher crushing efficiency and stronger stability

Daswell has always devoted itself to the research and development of mining machinery. Therefore, besides the roller crusher, we also have other crushing equipments like jaw crusher, impact crusher, cone crusher and hydraulic cone crusher. Moreover, we also can produce sand making machine and screens and feeders.
