Minimization of fines generation in size reduction of ...

Size 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.

Impact Crusher Working Principle

Starting 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).

TECHNICAL NOTES 5 CRUSHERS Mineral Tech

The 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.
