Stone crusher in stone production line

Impact crusher crushes material by striking energy. When works, the motor drives the rotor rotate at a high speed, on which the blow bar is installed. As soon as the material get into the affecting area of the blow bar, they will be stroke by the blow bar and be thrown to the impact devices around the rotor. The high speed forces the material to rebound from the impact liner to the area where the blow bar effects until they have been crushed to the required size. The clearance between the impact racks and the rotor can be adjusted to change the size and shape of the end products.
Gyratory and work in pretty much the same way, although they have slightly different designs. The rock falls into the top of a chamber with a spinning grinder at the bottom. As the stone falls down, it is squeezed between the grinder and the walls of the chamber and crushed. As it continues to fall down the chamber, it is pulverized into smaller and smaller bits until it falls out the bottom.
Most stone crushers have a hopper at the top — a container which holds the rock above the crusher and uses gravity to feed it in. Alternately, stone crushers can use a belt drive to continuously transport the stone into the crusher. At the bottom of nearly every type of crusher is a hole. Once a rock has been pressed into small enough pieces to fit through the hole, it exits the crusher either onto, a conveyor belt, into a bin or onto a large pile. In some cases, one rock crusher may feed directly into a second one, crushing the rocks up into finer and finer particles in two or three stages.
