Impact Crusher Working Principle

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). Dynamic impact could be described as material dropping into a rapidly turning rotor where it receives a smashing blow from a hammer or impeller. Attrition crushing is the reduction of materials by rubbing ...

Impact Force - Engineering ToolBox

The impact on a human body can be difficult to determine since it depends on how the body hits the ground - which part of the body, the angle of the body and/or if hands are used to protect the body and so on. For this example we use an impact distance of 3/4 inch (0.0625 ft) to calculate the impact force: F avg = (800 ft lb) / (0.0625 ft) = 12800 lb f. In metric units - person with weight 90 ...

Crushers - All crusher types for your reduction .

In the other crushers, most of the reduction is done by the impact of stone against metal. Customers operating old, rebuilt, or expanded plants often have problems with the shape of the product. In these cases, the addition of a Barmac VSI in the final crushing stage offers a solution to product shape problems. The same applies to many mobile crushing units. As the number of crushing stages is ...
