The locationsTruck and Loader Dumps can be a very significant source of dust. Often the location of the pocket is exposed to ambient wind that carries the dust generated from the dump into the air. DSI has experience that ranges from small front-end loader dumps to 120 ton Rail-Car Dumpers to 360 ton Haul Trucks dumping into Primary Gyratory Crushers.A powerful excavator loads the rock into dump trucks for delivery to the primary crusher. Crushing. Powerful hammers or metal jaws within the primary crusher break the rock down. Rock passes through a series of screens that sift it into different sizes. It may also pass through further crushing stages.

Crushing Plant Design And Layout Considerations

Mine haul-truck capacity is an important factor at primary crusher installations, because it is cost-effective to integrate truck cycle time at the crusher station with mineshovel operations. If a primary crusher dump pocket is undersized and unable to handle the mines trucks, then operators must slowly meter the ore into the receiving hopper.Mine haul-truck capacity is an important factor at primary crusher installations, because it is cost-effective to integrate truck cycle time at the crusher station with mineshovel operations. If a primary crusher dump pocket is undersized and unable to handle the mines trucks, then operators must slowly meter the ore into the receiving hopper.It is then transported by truck or conveyor to a crusher, where it goes through a series of crushing and screening stages to produce a range of final sizes to suit customers needs.
