Impact crushers involve the use of impact infused with the gravity force rather than pressure to crush material. The material is contained within the built-in cage, with openings on the bottom, end, or side of the desired size to allow pulverized material to escape. There are two types of impact crushers: horizontal shaft impactor and vertical shaft impactor. 

VSI crushers use a different approach involving a high speed rotor with wear resistant tips and a crushing chamber designed to throw the rock against it inner chamber. The VSI crushers utilize subject velocity rather than surface force as the predominant force to break rocks. In it's natural state, rock has a jagged and uneven surface. Applying surface force (pressure) results in unpredictable and typically non-cubical resulting particles which is the ultimate desired finish product you'd expect

The HSI crushers break rock by impacting the rock with heavy duty industrial hammers that are fixed on the outer edge of a spinning rotor. HSI machines are sold in stationary, trailer mounted and crawler mounted configurations. HSI are mainly used in recycling, hard rock and soft materials.

A jaw crusher uses highly compressive force for the breaking of particles. This mechanical pressure is achieved by the two jaws of which one is fixed while the other reciprocates. A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called a fixed jaw while the other jaw called a swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a hard lever or a particle cracker. 

Often just called screening equipment, is the procedure and practice of taking granulated or crushed ore material and separating it into multiple grades by particle size/shape/weight.

This practice occurs in a variety of industries such as mining and mineral processing rocks and gravel sizes that get sorted based on weight, shape, and other factors.

A cone crusher is similar in operation to a gyratory crusher, with less steepness in the crushing chamber and more of a parallel zone between crushing zones/chamber. A cone crusher breaks rock by applying consistent interment force over the rock between an eccentrically gyrating spindle, which is covered by a wear resistant mantle, and the enclosing concave hopper, covered by a resistible mineral concaved chamber or a heavy duty bowl liner.
