WhatsApp: +86 18838072829The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to m. Product: 300mm (for transport) to 200mm (for SAG mill) Feed Rate:
WhatsApp: +86 18838072829Because of this difference each type of crusher has its own environment that it operates best or at least better in, than the other. As an example, a gyratory crusher can be fed from two sides and handle ore that tends to slab. Also its design allows a higher speed motor with a high reduction ratio between the motor and the crushing surface.
WhatsApp: +86 18838072829The main difference between a mill and a crusher is that a mill uses grinding media (such as steel balls or rods) to crush or grind material into smaller particles, whereas a crusher uses pressure or impact to reduce the size of larger rocks or material chunks into smaller ones.

WhatsApp: +86 18838072829Crushers are used to reduce particle size enough so that the material can be processed into finer particles in a grinder. A typical processing line at a mine might consist of a crusher followed by a SAG mill followed by a ball mill. In this context, the SAG mill and ball mill are considered grinders rather than crushers.
WhatsApp: +86 18838072829Ball and Rod Mills. JeanPaul Duroudier, in Size Reduction of Divided Solids, 2016. Performance. Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture.
