“Further rock fragmentation measurement located on the crusher discharge conveyor offers advantages and presents different but important data. Firstly, installation on a fixed conveyor is simpler and more reliable than applications in the pit or at the crusher, secondly the crushed ore PSD is a more critical measurement particularly to AG and

Figure 5.1 Schematic diagram of a crusher showingg the open- and closed-side settings. 5.1 Jaw and Gyratory Crushers. Jaw and gyratory crushers are used mostly for primary crushing. They are characterized by wide gape and narrow discharge and are designed to handle large quantities of material. The capacity of the crusher is determined by its size.

For most friable materials, the efficiency is excellent because the physics works in our favor to produce a consistent discharge particle size distribution largely independent of the particle size distribution at the feed. For roller crushers, if there is any moisture content to the product, the product will not crush, but will flatten into

Jaw crushers. A jaw crusher is a compression type of crusher. Feed material is reduced by squeezing it between a moving piece of steel and a stationary piece of steel, with the discharge size controlled by the gap setting, ie the space between those two pieces of steel.

A crusher is not able to directly produce a specific grain size, so the discharge always contains a wide range from fines up to a maximum size, plus oversize. The solution is a crushing circuit with an arrangement of a crusher, a subsequent screen and a conveyor to return the oversize to the crusher.
