Mobile Crusher is Applied in Open Pit Coal Mine

The users of open pit coal mine are mainly power stations. The particle size of coal requested by power plants is less than 200 mm. Most small and medium size open pit coal mines have no crushing equipment. So the particle size of coal can not reach the requested standard. And that affects the economic benefit of coal mining directly. Build a stationary crushing plant, which not only needs lots of investment, but increases the secondary unlucky links and the cost of production SO the economic benefit of coal mining is not good. Mobile crusher can directly work at cal mining workshop. So it can crusher coals as soon as they are mined. Besides, the granularity is suitable.

According to the characteristics of open-pit coal mine producing, mobile crusher must have the function of walking, loading materials and reprinting besides crushing to meet the requirement of single bucket shipment. Mobile crusher can reduce some middle parts produced by crushing. Mobile crusher consists of the following components:

(1)Crusher. There are many kinds of crushers, jaw crusher and impact crusher.

(2) Crawler. In order to reduce shipping links, mobile crushing is required to move at any time. Crawler is more appropriate to work at the coal face with the mechanical loader buckets. Mobile crusher can directly use the crawler chassis of excavator or crane as the travel agency of mobile crusher. Mobile crusher uses motor driving wheel reducer, or a hydraulic motor.

(3) Feeding and reprint agencies: Mobile crusher needs a feeder to make the raw materials enter into the crushing machine evenly. Feeding machine uses the form of ring chain ---scraper conveyor. Bucket unloads coals into the tank feeding mechanism. Scraper conveyor send coals evenly into the crusher. The crushed coal must be transported out, so we need a reversed loader. We can choose belt conveyor as reversed loader. The length of belt conveyor is determined by the height of truck loading. The loader can be rotated to meet the requirements of loading.
