Wet Grinding and Classifying Plant

Crushing Circuit and Equipment

The crushed ores must to be grinded to meet the liberation condition to meet the next operation stage.

Wet grinding is often used in the mineral processing plants to improve efficiency, reduce consumption of energy and steel materials, and avoid over-comminution. According to the plan of grinding product size and capacity, grinding flowchart should be designed reasonably, and grinding machine is properly selected according to the size of ore and other properties.

Common grinding process may be one stage, two- stage or three stage. There are open circuit or closed circuit in grinding circuit. Closed circuit process is generally used to control grinding product size.

The common first stage grinding machines are AG mill, SAG mill, rod mill or ball mill and so on. The second and third stage grinding machines often use ball mill and others.

The common equipment which combine with grinding system to be closed circuit aretrommel, vibrating screen, spiral classifier or hydrocyclone.

Grinding Circuit Examples

Many kinds of the designed grinding circuit are suitable for different processing plants. Three circuit examples of crushing plants are following.

SAG mill – ball mill closed grinding circuit

Two stages of ball mill closed grinding circuit

One stage of ball mill closed grinding circuit
