Calculate and Select Ball Mill Ball Size for Optimum Grinding

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and

tests. Besides particle size reduction, ball mills are also widely used for mixing, blending and dispersing, amorphisation of materials and mechanical alloying [1, 49, 51]. As a construction, a ball milling device usually consists of a cylindrical vessel mounted on an appropriate basis at both ends which allows rotation of the vessel

The Main Factors Affecting the Particle Size of Ball

The main factors affecting the particle size of ball milling. 1. Material of the milling tools (milling jars and balls). Milling tools selection depend on sample characteristics. Normally, the milling jar material must be harder than the material to be milled. 2. Milling balls/sample/solvent ratio. 3. Milling ball size. 4. Working time. 5. Grinding speed
