The impact block is one of the main parts of the impact crusher, and the impact plate hammer is equally important, can protect the machine to reduce wear.  If the use of wear resistance is relatively high impact resistance of the impact block wear-resistant impact block, not only can prolong the service life of the impact crusher, but also can improve the production capacity of the impact break.  

Counterattack piece of material on the market at present generally have high manganese steel and high chromium alloy, according to the characteristics of the counterattack crusher, according to the users of the crusher and the crushing material used situation, with high chromium alloy casting and high manganese just do texture into wear-resisting counterattack, through many years research and development aspects of improvement and the external shape inner material process improvements,  Now the factory counterattack block has dense organization, high wear resistance, strong impact resistance, suitable for large and medium-sized counterattack crushing machine, appreciated by the majority of users.  

The impact block is an important and vulnerable part of the impact crusher. The resistance ability of the lining plate decreases after aging, which often causes the lining plate to be shot down, and also causes the decrease of the sealing performance of the crusher to produce large dust.  After opening the shelf, remove the cotter pins, slotted nuts and bolts used to fix the counterattack block to replace the worn counterattack liner.
