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 ...

Ball mill that works on the principle of impact is an efficient technique of size reduction through grinding. The size reduction is an important factor for many industrial applications as this process is carried out to increase the surface area, to intimate mixing and to improve dissolution rate, solubility, binding strength and dispersion properties. Therefore it is important to maintain the size of products there are many

01.09.2013  The ball size is one of the critical factors for determining the mill performance of ball mills. It is well known that larger balls are needed for the effective breakage of large-size particles, whereas smaller balls are more effective for the breakage of fine particles. Therefore, it is a common practice in industry to use a mixture of balls rather than balls of a single-size to ensure the efficient grinding of

typical ball size of ball mill - zs-u-trojice.cz

Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement ...

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse ...
