Crushers: 5 types and their main failures
Impact Crusher. The impact crusher uses the force of impact to reduce the size of the material. This reduction occurs both through the impactors and through the abrasion caused by contact with the housing or the impact bars. The high operating speed of the impact crusher makes it equivalent to two to three stages of traditional crushers.
