Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
Ball mills are further characterized by the major differences in the sizes of grinding jars and what ball sizes are readily available. Retsch can supply ball mills with jar capacities ranging from 1.5 ml up to 150 l, and balls are available in sizes ranging from 0.1 mm to 40 mm, see Figure 2. Figure 2.

Small Ball Mill Capacity & Sizing Table Ball Mill Design/Power Calculation
Hard ore Work Index 16 = 100,000/65,000 = 1.54 kwh/t. For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the increased energy input of 1.54 kw/t reduces the ball mill feed size to 6,500 micrometers. As a result, the mill output will increase with this reduced size to approximately 77,000 tons ...
Top ball size = 80 mm; Ore density 2.93 t/m 3; Table 5 presents results of a single ball mill survey. The survey measured motor input power. Drives are assumed to have an efficiency of 0.96 and gearbox+pinion efficiency of 0.970, so the model shell power draw is converted to motor input power by dividing by 0.9312.

Tumbling ball mills: These mills are similar to vibratory mills but use a rotating drum instead of vibration to grind materials. Tumbling ball mills are often used for high-capacity applications and can produce very fine particle sizes, making them ideal for grinding pigments, chemicals, and other materials.
The acceleration factor of the ball or rod mass is a function of the peripheral speed of the mill. Thus. n = c9np/√D, the above equation becomes P = f1 (D²)·f5 (πD c9 np/√D) = cs np D2.5. As a first approximation, the capacity, T, of a mill may be considered as a function of the force acting inside the mill.

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 ...
Valid data shows that the suitable loading degree of the tumbling ball mill is 80%-90% of the total volume. Generally, the total load should not exceed five-quarters of the total capacity of the tumbling ball mill. Therefore, grinding steel balls generally account for 45%-55% of the total volume. In this range, the tumbling ball mill has the ...
