Here, : G=9.6×3.82.5=270.2 t/h, the production capacity per hour can meet the demand. The production capacity of grinder mill is formulated 265TPH which is in a safe range and conservative. 2.1.2 Drying Capacity: Gd=KdD2.5. Gd refers to the drying capacity of …Optimizing Primary Grinding Capacity. The relation of fineness of grind to the degree of liberation of the valuable minerals from the gangue is certainly a factor to be considered in optimizing the primary grind. This largely determines the grind-recovery curve and the point of maximum recovery, which is normally at a very fine grind.

1) Rod milling – a rod mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit. 2) Ball milling – a ball mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit.Calculate Capacity Of A Grinding Mill. calculation of circulating load of a grinding mill. formula for grinding mill circulating load. mills, i Rod mill using media rods of 8cm diameter, and ii Ball mill using index, and solid percent of pulps in order to calculate the circulating load and load during the 7 days were estimated based on the following equation 3, using the.

It was, therefore, ground in a wet rod mill 2.85 m × 4.27 m using steel rods of 4.11 m in length. The total mass of the rod charge was 63.8 t. The test work index was 13.2 kWh/t. During steady-state grinding the mill consumed 6.41 kW/t of rods. Calculate 1. the percent mill volume occupied by the charge during wet open circuit grinding, 2.The performance of tumbling mills is sensitive to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to contin-uously optimize mill operation, it …

To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill.
