And crusher equipment as the main quarry equipment, its strong one of the mechanical properties of the nots allow to ignore, below we went from plate hammer and counterattack board two aspects to introduce its mechanical properties.
(1) plate hammer
Plate hammer appearance and tighten way and closely related work load. Plate hammer design should be satisfied with reliable work, loading and unloading is simple and improve the utilization ratio of metal plate hammer requirements. Plate hammer generally USES high chromium cast iron, high manganese steel and other wear-resisting alloy steel. Plate hammer shape many, there is elongated, T shape, S form, work form, axe shape and take groove shape, such as general now for rectangular.
(2) counterattack board
Counterattack board's role is to inherit be plate hammer hits the impact, which materials of material impact and broken, and will impact crushing materials to bounce back after impact area, make another impact crushing to obtain the granularity of product.
Counterattack plate is very much, basically have the form of folding linear and curve form two kinds. Fold the linear counterattack surface can make each point on the counter attack board materials are approximate vertical direction, so you can get the best impact crusher effect. Circular face can make the material blocks back by counterattack board after rebound out in the impact of the circle formed intense area, to increase crushing zone of material free impact crusher effect.
Counterattack board generally USES the steel plate welded. On the counter with abrasion resistant linings, but also used counterattack roller or grate bar composition. The counterattack surface with grate seam, its product is less, fine particle level content can improve equipment production ability, energy saving. But there are complicated structure, and counterattack surface after wearing hard to replace, wear fast wait for blemish.
Impact crusher rotor made mostly adopts the whole cast steel structure, firm is durable, easy to install plate hammer, its quality is big, can satisfy broken requirements. Small and light Impact crusher rotor also can use plates welded together.
