AMIT 135: Lesson 7 Ball Mills & Circuits Mining Mill

Mill Power Draw. The motor power draw required to turn a mill from rest to the operating speed includes the energy required for the initial starting torque and mechanical arrangements to rotate the mill. It is generally accepted that practical mill power (PM ) is a function of mill capacity and diameter, i.e.,P M = Mill Constant * (Mill

Ball Mills an overview ScienceDirect Topics

Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho, private communications).

Calculate Ball Mill Grinding Capacity

The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent. It is especially difficult to teach mill

Ball mill upgrade at Collahuasi increases processing

Ball mill upgrade at Collahuasi increases processing capacity by 4.4% The upgrade was achieved without safety incidents in 71 days, 13 days ahead of the initial schedule. It involved changing the rotor, GMD system stator and redesigning the mill discharge to achieve an increase in both available power and the level of filling required to treat

TECHNICAL How to Spec a Mill Gear Power & Transmission

mill to be processed, the typical mill speed is ~75% of the theoretical criti-cal speed of that mill. Using the above formulas, significant experience of how the grinding process works, and mate-rial properties of the ore being ground, the mill builder can provide the gear designer with input power and output speed.

Ball mills liming

Three types of tests are available for mill power determinations. In most cases one of two bench scale tests is adequate. First, a Jar Mill grindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hp-hr/t) to grind from the design feed size to the required product size.

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. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

(6) gives: W = 11.01 kWhlshort ton or W = 12.13 kWhlt For a capacity 500 tIh, the total required mill power is 12.13 kW hit x 500 tIh = 6050 kW. Thus, if two (2) ball-mills are used the power drawn from each Denver mill must be (605012) = 3025 kW. The internal mill diameter D (m) calculated from Eq.
