primary ball mill circuits

Karara Mine has decided to shift the comminution workload from the primary ball mill to the TowerMill circuit by bypassing the 100 µm fine screen in between the ball mill and TowerMill circuits. This action has increased the circuit feed particle size distribution with a top size close to 1 mm.

Table 2 provides a simple comparison of the various comminution circuits. The primary mill may be operated in open circuit or closed by a classifier, such as a screen or a hydrocyclone. Closing the primary mill may result in an improvement in operating efficiency for some operations, or may facilitate a reduction in the primary mill product size.

Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost. In today's global markets, expanding mining groups are trying

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume .

Ball Mill Grinding Circuit. Even though many ores require fine grinding for maximum recovery, most ores liberate a large percentage of the minerals during the first pass through the grinding unit. Thus, if the free minerals can be immediately removed from the ball mill classifier circuit, there is little chance for overgrinding.

A ball mill consists of a cylindrical shell rotated about its axis by a motor. Heavy metallic balls called grinding media are loaded into the cylinder. The coarse ore (usually from primary crusher) is fed into the mill together with water in wet grinding. The tumbling action of the balls within the revolving mill crushes the feed to finer sizes.
