FLSmidth - Crusher - EV Hammer Impact Crusher

How it works

The EV™ hammer impact crusher reduces quarry size limestone boulders to mill feed in only one reduction, giving a reduction ratio of 1:100. The hammer rows are fitted in a staggered arrangement to give complete coverage across the outlet grate. The hammer assembly provides several points of attack on the raw materials, increasing the overall efficiency of the impact crusher. 

The crushed product has a relatively high proportion of fines and more of the comminution work is therefore moved from the less energy efficient raw mill to the more energy efficient impact crusher.
