In the realm of mineral processing, the foundational stages of crushing and grinding play a pivotal role in the reduction of ore particles' size, a prerequisite for subsequent separation processes. Crushing involves the initial breaking down of the ore into smaller pieces using various crushers like jaw crushers, cone crushers, and …
An alternative for secondary crushing is impact crushers using mass and velocity to break soft to medium-hard rocks. Rocks break along natural cleavage plains resulting in better shape. The material gets thrown back into the blow bar until it reaches the size of the discharge gap, reducing materials from ratios 10:1 to as small as 25:1
Table Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl liner.Gyratory crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface. As the gap …
