Aug 02, 2013· 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

THEORETICAL CALCULATION OF MILL STEEL BALL SIZE. Abstract. From the principle of crushing machanics, a theoretical formula for calculating ballsizes for ball mills has been derived.

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed

Ball Size as Initial Charge. Commercial ball sizes 10 150 mm; Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., dâ†“V = 0.40

Ball Mill is primarily used for fine grinding.It is key equipment which repulverises the material after it is crushed. Kefid company has been amongst the pioneers for many years in the design and application of milling systems for the size reduction of a wide variety of materials including minerals, ores, and coal.

circuits at Paora Mining Company. Each milling circuit consists of a rod mill followed by a ball mill in series. Crusher product (-9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill. The ball mill discharges to a sump

Sagmilling is home to a collection of both free and subscription-based calculation tools to aid metallurgical process engineers perform comminution calculations. Grinding circuit design tools, including for SAG mill-ball mill circuits, and geometallurgy energy models are availe to subscribers.

THEORETICAL CALCULATION OF MILL STEEL BALL SIZE. Abstract. From the principle of crushing machanics, a theoretical formula for calculating ballsizes for ball mills has been derived.

On top of this, many companies treat different parts of their mining operations as independent units. It’s not uncommon for a large mine to have independent planners looking after blasting, primary crusher throughput, secondary and ball mill grinding as well as the concentration plant.

AG/SAG mills can accomplish the same size reduction as two or three stages of crushing and screening, a rod mill, and some or all of the of a ball mill. Because of the range of mill sizes availe, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit. A diagram of types of AG/SAG
