Crushing Plants

Mobile crushing plants are built ready-mounted on their own travel gear. Semi-mobile plants, on the other hand, are moved from one location to the next as a piggyback load on separate haul units. Each crushing plant comes ready to operate with its own feed hopper, feed conveyor, discharge conveyor and material transfer belt. The size and design of the crusher naturally depends upon the work that it is intended for.

Crushing Plants

Semi-mobile crushing plants are always to be recommended when a change of location in long periods is required in order to optimize the raw material transportation- and operational-costs of the quarry department.
