SAG Mill Ball Size Evaluator | Evaluation Factors

SAG Ball consumption is "average" at 400 g/t while Ball Mill grinding media (3″ balls) usage in 550 g/t. Yet, you add steel and nothing seems to happen, tonnage is not noticeably improved. You need more tonnage and could actually use a larger/coarser transfer size from the SAG to Ball Mill. The ore is "hard" and "bulky".

Grinding Mills and Their Types

Ball mill is a versatile grinding mill and has a wide range of applications. The mill can vary in size from small batch mills up to mills with outputs of hundreds of tons per hour.

Principles of Grinding in Ball Mills

Principles of Grinding in Ball Mills. Action inside a Ball Mill drum is not a haphazard process. Stirring is not random nor is the throwing of the charge. There is a very specific operating speed for the most efficient grinding.

Ball Mills

Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation.

Ball Charge and Grinding Efficiency

Ball mill grind is based on different principle; it has some attributes similar to SAG mill optimization. SAG mill breaks with stirring the kidney at optimized kidney specific gravity and maximum stir rate per mill revolution, whereas ball mill breaks down ore with increasing particle-to-ball interaction.

Grinding Ball Design

The opposite effect occurs in Climax 3 and 4 m (9.5 and 13 ft) ball mills. These grind less than 9.5 mm (0.3 in.) ore that requires 76 mm (3 in.) top size balls. The size distribution resulting from use of martensitic steel balls with softer centers was found to be less effective than a charge of uniform hardness but softer carbon steel balls ...

Exploring Ball Mill Diagram: A Comprehensive Guide

The grinding action in a ball mill is achieved through two primary fragmentation mechanisms: attrition and the impact. Impaction happens when the grinding media (balls or hard pebbles) bump into each other and with the material being ground. This leads to the fragmentation of the substance into pieces of smaller size.
