 · Impact crushers are traditionally classified into two main types, horizontal shaft impact (HSI) crushers and vertical shaft impact (VSI) crushers. These different types of impact crushers share the crushing principle, impact, to reduce the material to smaller sizes, but features, capacities and optimal appliions are far from each other.

The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with onethird of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.

Gyratory crushers are also used as aggregate crushers. These types of crushers are similar to jaw crushers, but employ a cone shaped hopper with a smaller coneshaped crushing head that gyrates around the inside of the hopper in an eccentric movement rather than rotating, crushing the source material until the particles are small enough to fall through the opening at the bottom.
