Most of the surface mine user power plant, power plant coal supply requirements to a particle size of less than 200 mm. The majority of small and medium-sized surface mine do not have the crushing plant, coal particle size below standard, a direct impact on the economic benefits of the coal mine. Built a fixed crusher station, just a one-time investment, but also secondary unlucky links, so that the increase in production costs, but also affect the economic efficiency of the coal mine. Mobile crusher directly placed in the coalface broken edges, with the shovel edge coal loading, can solve the coal particle size.According to the characteristics of the surface mine coal mining production, to meet single bucket shipment requirements, mobile crusher in addition to the need to have their most important function broken, need to have their own go outside, functional feeding and reprint loading. As much as possible to reduce intermediate links, reduce tons of coal cost increase in the crushing process. The mobile crusher consists of the following components:
(1) crusher. Many types of crusher can select the song moving extrusion type jaw crusher, impact broken Crusher.
(2) crawler system. In order to reduce the shipping link, broken function to move at any time. Coalface with the loader buckets mechanical work, crawler travel more appropriate. The crawler chassis as mobile crusher walking institutions, can be directly used excavator or crane motor through the wheel side reducer drive, hydraulic motor can be used to drive.
(3) on the material and reproduced agencies. Coal into the crusher evenly in order to be broken, you need to set the feeding mechanism. On the feeder ring chain --- the form of scraper conveyor. Bucket mechanical unloading coal to the feeding mechanism of the discharge tank, scraper conveyor coal into the crusher evenly. The coal crushed needs loading transport, and therefore need to set the loader. Reproduced the machine selects belt conveyor determine its length, loader rotation, in order to adapt to the requirements of the loading height loading requirements.
