Importance of Jaw Crusher in Phosphorus Plant

Jaw crusher , commonly known as jaw broken equipment, it is composed by the moving jaw and static jaw these two jaw plate crushing chamber, which relays on the two jaw movements of simulated animals to complete the material crushing operations crusher. And widely used in the crushing of medium-grained ore and bulk materials in the mining, smelting, building material, highway, railway, water conservancy and chemical industry. The highest compressive strength of the material being broken is 320Mpa.
At present, like the other crushing equipments, such as cone crusher, impact crusher,  jaw crusher  was adopted more in small phosphate plant, jaw crusher move with force by movable jaw plate cycle to pressure to the fixed jaw plate, clip and crushing the material . The two jaw plates are rectangular, the existing jaw crusher jaw plate swing form can be divided into simple swing and swing of the two types. The jaw crusher is generally used for crushing operations. Small and medium-election phosphorus plant, ore particle size is relatively small and can be used in both pieces. It is the most commonly used a simple swing the elbows plate jaw crusher in selected phosphorus plant.
It comprises of the following main components: Frame or rack, hanging axis of the movable jaw plate, eccentric shaft, connecting rod, bracket, flywheel side of the liner, the fixed jaw plate, two jaw pull liner with the spring lever, adjust the block. General motor is droved through the belt (and more generally with the V-belt) so that the eccentric shaft rotation. When the eccentric turn to the top of the rod upward movement of the drive bracket, the bracket gradually stretched flat toggle plate will be forced to promote the movable jaw plate to the fixed jaw pull ore crushing chamber was broken. Eccentric turn to the bottom of the rod downward movement, the toggle plate and movable jaw plate by the force of the spring and rod to the back port of discharge increases, the broken ore is discharged from the port of discharge mouth. The eccentric shaft of a turn each half cycle for the broken to enhance the half-cycle force of  the row of ore.This makes it half the time the motor is idling, that is, the motor load is not balanced. This has a flywheel to this part of the energy savings should be used broken. General after the design strength of the bracket is lower, when the lump ores fall into the crushing chamber, after the bracket by a sudden force is automatically broken, to avoid the movable jaw plate, connecting rod, eccentric shaft and the base of these important components are damage. The lining of the jaw crusher plate directly in contact with the ore, easy to wear, the general use of manganese steel manufacturing, and the board appear before the dentate to the crushing force.
