Impact crushing is a crushing method where comminution is by impact rather than by compression. Sharp blows are applied at high speed to freefalling rock. The moving parts are beaters, which transfer some of their kinetic energy to the ore particles on contacting them.
Get PriceWhat is an Impact Crusher? An impact crusher is a machine that uses striking as opposed to pressure to reduce the size of a material. Impact crushers are designated as a primary, secondary, tertiary or quarternary rotor crusher depending on which processing stage the equipment is being utilized.
Get PriceHorizontal shaft impact crusher (Hsi) As much as 24:1 reduction ratio and are often run as primary or secondary crushers, occasionally tertiary. Normally are used with soft to mild stone. If utilized in hard abrasive materials, the wear cost and associated downtime is normally not acceptable.
Get PriceSize reduction in an impact crusher can not be modeled by single particle breakage phenomena, because it accounts only for particle and the impeller collisions. A particle, in an impact crusher, collides not only with the impeller and the crusher walls but also with other particles. These particletoparticle collisions are very weak in nature.
Get PriceMost impact crushers are secondary crushers, but there are primary impact crushers as well. With higher reduction ratio than the jaw crushers and with dependable crushing performance, the primary impact crusher is capable to crush even the hardest materials.
Get PriceStarting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them. Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill).
Get PriceThe gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1.
Get PriceGenerally, every crusher machine is not the same, here are several common crusher size reduction ratio: The impact crusher size reduction ratio is 20 to 1. The vertical shaft impact crusher size reduction ratio is 48 to 1. The vertical roller mill size reduction ratio is to 1. The hammer crusher size reduction ratio is 20 to 1.

Get PriceLaboratory Jaw Crushers are designed for economic size reduction of typical aggregates and common minerals at an output scaled for laboratory testing. Adjustable jaw openings allow close control of output size. High operating rpm promotes efficient size reduction with lower dust generation compared to other crushers and pulverizers.
Get PriceSize Reduction is mainly done through crushers and mills. Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on the "runofm ine" ore.
Get PriceThe operation is similar to the standard cone crushers, except that the size reduction is caused more by attrition than by impact [5]. The reduction ratio is around 8:1 and as the product size is relatively small the feed size is limited to less than 50 mm with a nip angle between 25° and 30°. The Gyradisc crushers have head diameters from ...
Get PriceImpact crushers are often used for secondary pulverizing rather than primary pulverizing and are often referred to as impactors as well. Impact crushers can be used on soft, mediumhard and very hard materials, both abrasive and nonabrasive. As a result of the wide range of materials they can pulverize, a wide range of industries make use of impact crushers.
