The Application of 10-40 ton/hour cement plant ball mil, cement mill for grinding cement clinker : Ball mill is an efficient tool for grinding many materials into fine powder. 1.The Ball Mill is used to grind many kinds of mine and other materials, or to select the mine. 2.
Ball Mill Design/Sizing Calculator; The power required to grind a material from a given feed size to a given product size can be estimated by using the following equation: where: W = power consumption expressed in kWh/short to (HPhr/short ton = 1.34 kWh/short ton) Wi = work index, which is a factor relative to the kwh/short ton required to ...
•Work Index, Wi, is the gross energy requirement in kilowatt hour per ton of feed (kWh/ton of feed) to reduce a very large particle to such a size that 80% of the product will pass through a 10micrometer, or 0.1 mm screen. •If Dp is in mm, 𝑊𝑖=𝐾 1 𝐷𝑝𝑝 𝐾 = 0.1𝑊𝑖=0.3162𝑊𝑖 I =0.3162𝑊𝑖 1 𝑝𝑝 − 1
Power consumption per ton of cement can be reduced by 8 ~ 12 kWh, representing 15% to 30% saving over a traditional ball mill system. System output can be increased by more than . Specific energy consumption is around 30 kWh/t-cement for grade 32.5 and around 33 kWh/t-cement for grade 42.5 (MIIT, 2012. p.25)
