Impact In crushing terminology, impact refers to the sharp, instantaneous collision of one moving object against another. Both objects may be moving, such as a baseball bat connection with a fast ball, or one object may be motionless, such as a rock being struck by hammer blows. There are two variations of impact: gravity impact and dynamic impact.

Impact force occurs whenever two surfaces or bodies collide, delivering energy in the form of an instant shock. In the design of a product, device, or piece of equipment, technology to measure and quantify impact force can go a long way in improving the design’s durability, among several other processes.

Compression force (or compressive force) occurs when a physical force presses inward on an object, causing it to become compacted. In this process, the relative positions of atoms and molecules of the object change. This change can be temporary or permanent depending on the type of material receiving the compressive force.

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.

Impact crushers: they involve the use of impact rather than pressure to crush materials. The material is contained within a cage, with openings on the bottom, end or side of the desired size to allow pulverized material to escape. This type of crusher is usually used with soft material such as coal, seeds or soft metallic ores:

and this reduces the crushing force. If the diameter of the crank plate is high, then the piston reciprocates slowly and the crushing force exerted by the piston will be really high thus damaging the bin which is at the end of the piston. Therefore, optimum diameter of the crank plate should be maintained for the effective operation [3].
