Impact Plate

Use of the product:

Supporting counter-counter impact crushers are used, suitable for mines, construction, roads, water conservancy and other fields. It is used for the crushing operation of all kinds of medium-hard and brittle materials, helping the production of sand and stone aggregates, ore processing, etc., ensuring the smooth and efficient crushing process, and adapting to the needs of crushing production lines of different scales.

Application scenario:

Impact Plate is one of the core wear-resistant and fragile components in impact crushers. It is widely used in mine crushing, sand and stone aggregate production lines and building materials industries. It is used for secondary counterattack crushing and particle type optimisation of materials after high-speed impact.

In practical application, the counter-back plate is installed inside the crushing cavity of the counter-impact crusher and works with the plate hammer. When the material is thrown out at high speed, it hits the impact plate and breaks for the second time, thus effectively reducing the particle size and improving the finished particle shape. In the sand and stone production line, it is mainly used in the medium and fine grinding stages, and is an important key part to improve the quality of the mechanism sand.

It is widely used in the field of material processing such as granite, limestone and basalt. It is especially suitable for construction aggregate production projects with high requirements for finished particle size, as well as infrastructure construction industries such as cement and road engineering. It is an indispensable wear-resistant accessory in impact crushers.

FAQ：

Q：What is Impact Plate and what is its function in PF impact crusher?

A：Impact Plate is the core wear-resistant lining plate of the PF series counterattack crusher. It is divided into first-level folding line counterattack plate and second-level curved counterattack plate, which are suspended and installed on the inside of the crushing cavity. Three core functions:

1. Rebounce secondary crushing: the high-speed impact of the stone after the high-speed plate hammer hits the counterattack plate, and the material is crushed again by the reverse impact force to refine the particles and reduce the needle sheet content;
2. Plastic and optimised particle type: the arc/folded line structure allows the stone to be repeatedly collided and polished, producing cubic high-quality aggregates, and meeting the high-standard engineering sand and stone standards;
3. Protect the mainframe shell: isolate the stone material and directly flush the counterattack broken frame to protect the fuselage from rapid wear. At the same time, the gap between the counterattack plate and the rotor can be adjusted to accurately control the output particle size of the finished product.

Q：Which counter impact crusher models are suitable for Impact Plate?

A：The full series is suitable for PF1007, PF1210, PF1214, PF1315 single rotor counterattack breaker, covering coarse and medium crushing full-specification models, divided into first-level and second-level complete sets of counterattack plates, which can be supplied with a complete set of Blow Bar.

Q：What kind of counterattack plate should be used for crushing hard dolomite and low-strength granite?

A：Priority Mn18Cr2 high chromium high manganese counterattack plate. The stone has sharp edges and strong impact. Ordinary high-manganese steel is easy to quickly grind out grooves and perforations. The surface of high-chromium material is automatically hardened after impact, which is wear-resistant and crack-resistant, reducing downtime and maintenance.

Q：What factors will shorten the service life of the Impact Plate?

A：1. The higher the hardness of the material, the sharper the edge of the gravel, and the faster the washing and wear; 2. Large metal steel bars and iron blocks enter the crushing cavity, and the instantaneous huge impact causes the liner to crack; 3. The gap between the counter-impact plate and the rotor is too small, and the material squeezing friction aggravates the loss; 4. Long-term 24-hour overload continuous operation accelerates fatigue wear.

Q：What are the quality advantages of the original Impact Plate compared with ordinary coarse castings?

A：Integrated precision intermediate frequency casting and moulding, complete water-toughness heat treatment eliminates casting internal stress, no sand holes, pores, crack defects; accurate design of folded line/arc crushing surface, reasonable material impact angle, higher efficiency of crushing and shaping; installation of hanging ear, bolt hole size standard, suspension fit without shaking, no unilateral situation The part accelerates wear and tear.

Q：Does the whole PF counterattack impact plate always have it in stock to support the bulk supply of long-term foreign trade?

A：The first and second-level Mn13Cr2 and Mn18Cr2 of the whole series of PF counterattack plates have sufficient spot inventory all year round. It has its own complete cast steel production line can be supplied in batches in batches all year round, supporting overseas sand and stone factories, long-term fixed-point collection of mines, and the annual stocking of agents, and can be packaged and shipped with a complete set of plate hammers.
