Crusher accessories is an important part of the counterattack crusher, need to change in the industry, also known as crusher parts, main plate hammer, side guard plate, back plate, Fang Gang, and other accessories by pressing block, high manganese steel, high chromium, high manganese compound etc. wear resistant materials and casting or forging.
1, plate hammer: the impact hammer crusher hammer adopts the high chromium alloy material and the latest manufacturing technology, the unique structure design, the finished product is cubic, no tension and crack, the grain shape is quite good, is the reliable high wear-resistant casting. When the board hammer is worn to a certain extent, it should be adjusted or replaced in time to avoid the damage of the fastener and other parts. Adjustment of the board hammer: open the rear cover with a hydraulic cover device. Rotate the rotor by hand, turn the plate hammer that needs to be adjusted or replaced to the repair place, and then fix the rotor. The parts should be removed from the repair door or from the middle of the frame. Remove the need in the hammer hammer lightly beat.
2, side guard plate: counterattack lining plate is an important vulnerable part of the impact crusher, and the resistance to attack is decreased after wearing and aging. It often causes the lining board to be shot down, and also causes the seal performance of the crusher to decrease, resulting in larger dust. Open shelves, remove cotter pin, for fixing impact plate slotted nuts, bolts, it will wear the impact plate after replacement, if the installation of new counterattack lining board, the above steps can be reversed.
3, counterattack board: the counterattack board is usually welded by steel plate. The back surface is provided with a wear-resistant lining board, but also can counter roller or grate lath, with a slot counter surface, the product of fine grain content is less, can improve the production capacity of equipment, power consumption province, but has a complex structure, back face wear hard to replace, abrasion and other defects.
4, Fang Gang: Fang Gang was a square, can be divided into welded and seamless. The steel is welded by steel plates welded together, made of square steel tube. Seamless steel is a seamless steel tube to pull and system. The compressive capacity is far greater than the seamed tube, square steel crusher to keep material from the front discharge effect.
5, pressing block: widely used in all kinds of mining machinery, good material, stable performance, can be made according to different requirements. When the load test is completed, the necessary adjustment should be made for the pressing block. The automatic clamping mechanism of the crusher clamping block adopts the way of cylinder drive, connecting rod mechanism and linear guide way, and realizes the sequence action of clamping, feeding, clamping at the other end, loosening and returning at the same time. The whole process is fully pneumatic control, the operation is accurate and reliable, and it meets the requirements of use.
