A self-propelled portable crusher has its own running gears, which work in the mining face, from the loading equipment (eg excavators) 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.
Divided by way of walking, portable crushers are divided into with fluid, track wheel, tire, track, move type. When we choose portable crushers, we must consider the functions like mining geological conditions, running gear under load, the frequency of walking, road gradient, location and exploitation of mining face and progress.
Stationary crusher itself can’t move on their own, with a special need for mobile 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. This portable crusher equipment in the mining pit sits near the center of the mining face level. It can take several months to move a few years, with the mining face to maintain a certain distance and height difference.
The overall function of portable crushing plant handling the entire unit as a whole, their work can be relocated within 48h. 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. Removing and reinstalling about 30d, each shift of not more than one set 3 ~ 5a. 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 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. Portable 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.
