Mobile crushing plants are usually tracked, skid or trailer mounted units designed for quarrying and in-pit applications. They are made up of three components: crusher(s), screen(s), and feeder(s). A crushing plant is highly desirable in situations where the mining face is irregular or moves often. The crushing component can either consist of a cone, jaw or impact crusher and customized for the type of material being mined.

Typically, a crushing plant can often replace the conventional dump truck fleet offering significant savings in production costs and a reduced load on the environment. The significance of this new way of mining is changing the face of very large operations, such as the Alberta oilsands, where a truck and shovel fleet has traditionally been employed. Recently, Suncor has announced it will start to replace some of its truck and shovel fleet with a mobile crushing system (MCS) at its Voyageur South mine. Currently these units are being offered by MMD Mineral Sizing (Canada) Inc. and Krupp Canada. The main advantages of these systems are that they can be moved right to the mine face continuously loaded directly by the shovel. The ore is then crushed in place and transported by a mobile conveyor for further processing. For further details of the pros and cons of using mobile crushing systems at the oilsands, we encourage you to read the article “The changing face of oilsands mining”.
