How to Size a Ball Mill -Design Calculator & …
2) Ball milling – a ball mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit. When the grinding conditions differ from these specified conditions, efficiency factors (Rowland and Kjos, 1978) have to be used in conjunction with equation 1.
Calculate and Select Ball Mill Ball Size for …
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 ...

Optimum choice of the make-up ball sizes for …
A grinding circuit simulation combined with ball weal law was used to determine the optimum composition of the make-up ball sizes in tumbling ball mills. It was found that the optimum composition depends on various factors, including the feed size, the product size, the mill diameter and the breakage parameters. In all cases, binary mixtures of two ball sizes (50.8 mm and 25.4 mm) performed ...
Ball Mill|Small Size Grinding Mills Sale
Rod mills are less common than ball mills for grinding minerals the rods used in the mill usually a highcarbon steel can vary in both the length and the diameter however the smaller the rods the larger is the total surface area and hence the greater the grinding efficiency our rod mills are for sale worldwide please contact us with .

Milling - Our Equipment - British Rema
This single unit is capable of milling materials up to a hardness of 10 Mohs and enables accurate and highly controllable particle sizes to be achieved, typically with narrow size distribution. A range of mill sizes is available for throughputs ranging typically from 0.5kg to 2 tonne per hour with average particle sizes as low as 1 to 2 microns.
A Method to Determine the Ball Filling, in Miduk Copper ...
Average Ball Abrasion For calculating of the average ball abrasion, average weight of balls after abrasion test was deduced by average balls weight before abrasion. At first, ball filling in the mill was spot 1% and the number of balls in mill was estimated as shown below (Equations 7, 8 and 9). 𝐴𝑏 = 4335.44-3636.78=698.66 g (7)

The average size analysis of an iron ore after preliminary crushing showed a P 80 value of 1173 μm. This was fed to a wet rod mill which produced a product 80% of which passed 150 μm. This was then charged continuously to a ball mill, which was required to produce a product of –34 μm for the purpose of pelletising the ore.
