The Use Of Mobile Crushers In The Minerals Industry

The concept of mobile crushers is not new. Since their introduction about twenty-five years ago, mobile crushers have continued to gain widespread attention. Mobile crushers reduce minerals in the open pit mine to sizes which can be transported by belt conveyors thereby reducing or eliminating the need for truck haulage. Truck haulage is costly, often representing as much as 50% of the total mining cost. More than 80% of the cost of truck haulage is for fuel and lubricants, tire replacements, and operators' wages, and it can be anticipated that the cost of these items will continue to increase at a steady pace. Compared to truck haulage, transportation by belt conveyor is more energy-efficient, less labor-intensive, and less subject to inflation. Therefore, mobile crushers, used in conjunction with belt conveyor systems, offer one of the most effective available methods of reducing energy consumption and mining costs,
