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

AMIT 135: Lesson 7 Ball Mills & Circuits Mining Mill

Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1.

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).

Ball Mills Mt Baker Mining and Metals

The capacity, or throughput, of a ball mill is directly linked to particle size of the ball mill discharge. For example, it takes approximately 3 times as long to achieve 200 mesh grind as it does to achieve 65 mesh grind.

(PDF) Effect of circulating load and classification

Ball mill capacity tends to increase with larger circulating loads, but this increase is restricted due to limitations in classification efficiency. and also that the throughput benefits of higher circulating load are limited due to classification efficiency. The effect of classification efficiency and circulating load was also investigated

Increase throughput and capacity in SAG mills

Replacing traditional steel cast mill liners with new lightweight composite liners is another way to increase throughput of mills. Major gold and copper operations have already started doing this in mills up to 40’ Ø and seen an improvement in the slurry discharge of up to seven percent.

Increase throughput and capacity in SAG mills

SAG mills are the main workhorses in the majority of comminution circuits globally. They need to be fed and kept working round the clock. But challenges can arise when capacity is not optimised causing unnecessary downtime and liner wear leading to the one sound operators do not want to hear the sound of the mills standing still.
