Counterattack crusher is one of the more widely used in the mining machinery crusher, counterattack crusher parts is an important component of the
counterattack crusher, needs to be replaced, the industry also known as crusher wearing parts, mainly plate hammer, side protecting plate, impact plate, Fang Gang, pressing block, wedge block, a positioning block, accessories by Gao Menggang, high chromium, high manganese composite wear-resistant materials such as cast or forged.1, hammer board: board hammer with high chromium alloy material and new manufacturing technology, unique structure design, processing products were cube, no tension and fracture, grain shape is quite good; high wear resistance castings of trust. Plate hammer wear to a certain degree should be timely adjust or change, in order to avoid fasteners and other parts of damage. Plate hammer adjustment: hydraulic clamshell device will cover open. The rotation of the rotor by hand, will need to adjust or replace the plate hammer to repair, and then fixed rotor. Remove the plate hammer positioning parts should be the plate hammer along the axial direction derived from the access door, or from the center of the frame hanging out. When removing the need of hammer in the plate hammer lightly beat.2, side protecting plate: counterattack lining board is an important vulnerability original counterattack crusher, liner wear resisting ability decreased after ageing, often causing the lining board are shot down the accident, also caused the crusher in sealing performance produce dust. After open shelves, cotter pins, dismantle fixed counterattack lining board with the slotted nut, bolt, it will wear after counterattack lining board replacement, if you install a new lining counterattack, upside down the steps.3, the impact plate: counterattack plate generally uses the steel plate welded. The back surface is provided with a wear-resistant lining board, but also can be used to counter roll or grate lath, with comb joint counterattack, the product of fine grain content is less, the production capacity of equipment can be improved, power consumption province, but has a complex structure, it is difficult to replace the counter surface wear, wear quickly such defects.4, Fang Gang: Fang Gang square, can be divided into welded and seamless. Seamed steel is welded by steel plates together, made of square steel tube. Seamless steel pipe seamless steel is modified by drawing and system. The compressive capacity is far greater than the welded square tube, counterattack type crusher is square to not let the material from the front exhaust function.5, a pressing block: widely used in all kinds of mining machinery, material is of fine quality, stable performance, according to the different requirements of production. Load test run is completed, to deal with the pressing block to make the necessary adjustments. Black and white machine pressing block has stable chemical composition, heat treatment process is reasonable, good wear resistance, excellent characteristic of high strength. The pressing block automatic clamping mechanism, mechanism adopts a cylinder drive, a link mechanism and a linear guide way, realize the pressing block, the other end of the clamping feeding, clamping, and release, return sequence action. The whole process is controlled by pneumatic control, accurate and reliable action, to meet the requirement of use.
