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 mine/shovel operations. If a primary crusher dump pocket is undersized and unable to handle the mine's trucks, then operators must slowly meter the ore into the receiving hopper.

Rock Crusher History. History tells us, it was in 1830, the first US patent was issued on a rock crushing machine.
