The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones. The cyclones send correct-size material on to flotation and direct oversize material back to the ball mill for further grinding.

The simulated product size distributions were found to display a close match with the measured product from an operational mill. Based on the maximum production of floatable particles, the best combination of make-up ball size was determined in relation to feed flow rate, feed size distribution and ball filling.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

2009-8-27 The aim of the control strategy is to minimize particle size to flotation for a certain ore feed rate, or alternatively to maximize ore feed rate for a specific required particle size. The control strategy is shown in Figure 1. The main parameter influencing particle size from the circuit is ore feed rate. Although other factors like water

2020-6-25 Working Principle Operation. The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the ...

Feed rate:With a high feed rate,less size reduction is effected since in this case the material is in the mill for a shorter time. Properties of the feed material:With a hard material,a smaller size reduction is achieved Level of the material in the mill:A low level of material in the mill results into a reduction in the power consumption.if ...

Milling Speed and Feed Calculator Determine the spindle speed (RPM) and feed rate (IPM) for a milling operation, as well as the cut time for a given cut length. Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill.
