The opencast coal mine is primarily employed power station as well as granularity necessity on the coal particles in the power station is smaller sized than 200mm. Nearly all medium and small opencast mines usually do not have portable crusher , to ensure that the granularity with the coal can't reach the requirement which straight influences the economic added benefits of your coal mines. Making a set of strong crushing station involves large one-time investment and increases the 2nd reshipment link, which increases the manufacturing cost and influences the economic added benefits of coal mines. Portable crushing station can be straight place about the doing work web-site with the coal mine and mines the coal and crushing and unloading with the very same time along with the electrical shovel, as a result greater solving the granularity trouble from the coal particles.
According the coal mining and manufacturing attributes in the coal mines, to satisfy the necessity of single bucket shipment, mobile crushing station need to have the functions of independent working, feeding and transshipment besides the crushing function to cut back the intermediate website link increased by the crushing procedure and lower the coal expense. Portable crushing station is mostly composed by the following components:
(1) Crusher. The styles of crushers are a lot of, and it is acceptable to decide on dynamic extrusion kind jaw crusher or influence crusher which crushes resources with impacting vitality.
(two) Track walking device. In an effort to cut down the shipping hyperlink, the crusher is necessitates to walk at any time. Around the working surface of coal mine, it truly is appropriate to implement track walking device to coordinate the work of load bucket machine. The prospects can right use track strolling chassis with the excavator or crane since the walking gadget from the mobile crusher and use the electromotor for driving by means of hub reduction gear or use hydraulic motor for drive.
(3) Feeding and reshipping device. In order to feed the coal evenly to crusher, it requires to put in feeding device. The feeder machine adopts round-link chain-scraper conveyor kind. The bucket machine unloads the coal towards the discharging chute of the feeding device as well as the scraper conveyor will even send coal towards the crusher. The crushed coal needs loading for shipment, in order that it requirements to put in reshipment machine.
