Target Grind Size. Another factor in choosing a grinding mill is the consideration of the feed size introduced into the mill, and the product required from the mill or mill circuit. This can be best illustrated by comparing two prevailing and diametrically opposite grinds. In the manufacture of standard cement by grinding cement clinker, the clinker is reduced from 1″ or finer down to a ...
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 510 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 . Get ...
Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the cross-section of the balls charged to the mill. With this in mind, it is interesting to make a qualitative comparison of the ball size distributions which should be generated by 76 mm pearlitic carbon steel balls versus 76 mm martensitic alloy steel balls in the 2.93 m mills.

If copper recovery could be maintained in line with liberation at a grind size approximately 50–60 μm coarser than the current plant grind it would have significant implications for operation of the mill. In practice, this may only be applicable if the increased grind size is still within the normal flotation range and the flotation procedure can be modified to handle the coarser particles.

Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a grinding process. Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to help grind ore, however these mills contain a large screw mounted vertically to lift and grind material ...

My experience is that using a similar charge size distribution in a similar tumbling mill will typically require a longer grind time to achieve the same target p80. The breakage mechanisms and characteristics must therefore be different and this in turn will have an effect on surface chemistry and reagent adsorption. So it appears that we are seeing both a physical effect in breakage ...

For the porphyry copper ore tested in these investigations, a coarse copper sulphide grain size coupled with a high association with hard microwave-transparent (i.e. quartz) and hard microwave-heating (i.e. pyrite) minerals resulted in a grind size increase of 50–60 μm for equivalent liberation or an approximate 2.5% increase in liberation at an equivalent grind size.

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.
