The Portable crushing unit is placed in the open pit on the level of work with the stripping down the mining face advance and is extend to a certain distance. Track vehicles and other traction devices with Portable crushing units will conduct an overall migration.
Portable crusher station feeding, crushing and discharging device compose the excellent Portable crusher station. The crushing process is: Stripping face after blasting, ore cars loaded with excavators, transported to the stop Portable crushing plant to discharge into the feeding device, and then into the crusher system, crushing, broken after the passing ore, rock transported into the tape machine and drain abandoned factory site selection.
A movable portable crusher has its own running gear, it is to work in the mining face, from the loading equipment directly to the material, when the advance of mining work for the former, it is to move forward together with the loading equipment. Portable Crusher set the frequency shift depends on the advance of loading equipment. As the crusher moves around, so you need to configure highly flexible belt system.
Can crusher itself cannot move on their own, with a special need for Portable devices - track truck or truck tires. Vehicles can travel to the crusher below the crusher with hydraulic unit from the top, and moved to new locations. It can take several months to move a few years, with the mining face to maintain a certain distance and height difference.
Crusher will be moved into the unit to the feeding device, crusher and discharge devices Part 3, also removable into a smaller size and weight of moving components. Semi-fixed crusher mounted on a steel platform, the program moved less than a set time interval, with the extension of open-pit mining, crushing machine will be set down repeatedly, until the end of open-pit mining.
The Portable crushers unit of composition
Portable crusher unit generally consists of three mutually independent components, namely, crusher, feeding device, unloading device, the system also includes maintenance, truck. Into three separate parts of the system, were relocated with the truck. Portable crushing plant equipment and general metal structural members only, there is no concrete and foundation engineering.
Crusher is the core equipment, the production capacity of its units play a decisive role. Used Portable crusher jaw crusher has, cycle type, rotating jaw, hammer, back-and-roller and so on. Select the crusher into account when mine production capacity, the nature of ore, size and other requirements of the product. Hard rock selection generally broken jaw crusher and crusher cycles; broken in the hard rock mining multi-cycle type, rotating jaw, jaw, and counterattack hammer type; broken with soft rock and more roll crusher.
Cycle type and are usually used for rotating jaw crusher can move on, hammer, counter type, multi-roll crusher used on their own, and thus the production capacity is relatively small, limestone and coal used for other non-metallic mines. Most of the use of large metal mines to gyratory crusher as the main unit.
