Get PriceWhat are the dimensions of the ball mill you are looking at? 40% ball charge is quite high (unless you are looking at a small mill). A difference (duty vs. maximum) of 5% to 10% is fairly typical and you would likely struggle to perceive an energy efficiency difference between the two operating points
Get PriceIn order for the ball mill to perform normal grinding operations, its working speed must be less than the critical speed. Ball mills generally work in a “dropped” state. There are many working speeds to achieve this working state, but there must be the most favorable working speed. 1. If the rotating speed is low, the ball in the ball mill
Get Priceefficiency of ball mills . Keywords . Monitoring, electric motor, ball mill, efficiency. 1. Introduction . Mineral mills are machines used in those production processes which require the comminution of a certain material. The characteristics and operating principles of these mills can be very different, depending on the specific
Get Price(“Ball mill classification system optimization through functional performance modeling,” Nov. 17, McIvor et al., 2017, Mining Engineering) described circuit classification system efficiency (CSE), equal to the percentage of coarse (plus circuit P80 target size) material in the ball mill. It can be measured and then increased through
Get PriceMaximum efficiency. Liner wear is directly correlated to the ore trajectory in a grinding mill for a given RPM. As the liners wear, the ability to strike the toe at higher volumetric fills may not be possible. In cases where this is true, the volumetric load will automatically be decreased until the toe is impacted, thus restoring maximum
Get PriceA ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls
Get PriceDec 12, 2016 Ball Mill Power Calculation Example A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size
Get Priceuse a rod mill F80 of 16,000 m and a rod mill P80 of 1,000 m. Note that—in order for no correction factor for ball mill product fineness to apply—the ball mill circuit P80 should be no less than approximately 70 m (Bond, 1962). This Bond Efficiency determination should not be applied to cir

Get PriceTherefore, it is necessary to adopt modular technology and power control with optimum efficiency (problems with low efficiency at low load) for a sizeable gearless ball mill. With the development of large motors, fractional slot-concentrated winding [ 1 , 2 ] and modular technology have been widely used
Get PriceThe energy efficiency in a ball mill is very low (approx. 5%), since ... The maximum efficiency occurs when the mill feed fills all voids between the balls. Murdalier... More details Get Price
Get PriceAn inefficient ball mill is a major expense and could even cost you product quality. The best ball mills enable you to achieve the desired fineness quickly and efficiently, with minimum energy expenditure and low maintenance. With more than 4000 references worldwide, the
Get PriceGenerally, filling the mill by balls must not exceed 30%–35% of its volume. The productivity of ball mills depends on the drum diameter and the relation of ∫ drum diameter and length. The optimum ratio between length L and diameter D, L: D, is usually accepted in the range 1.56–1.64
Get Pricemaximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between mill absorbed power and ball filling degree. As indicated on the graph, a small variation in power could be the result of a
Get PriceFeb 13, 2017 Ball-Rod Mills, based on 4″ liners and capacity varying as 2.6 power of mill diameter, on the 5′ size give 20 per cent increased capacity; on the 4′ size, 25 per cent; and on the 3′ size, 28 per cent
