power consumption in ball mill grinding mill china. ... By installing a combined roller press andball mill grindingsystem in a 2400tpd cement production line, Tianjin Zhenxing Cement Co, Ltd. reduced specific energyconsumptionby 7.0 kWh/t-cement. For an annual production of 900 000 tons, this provides a saving of around 6.3 TWh/y (MIIT, 2012. p.25)
Specific power consumption decreases by about 10%. Reductions in specific energy consumption in the range of 7-24 kWh/t-cement are reported (LBNL, 2008) 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 .

Charge behaviour and power consumption in ball mills. The change in power consumption between the best and worst lifter shapes is now 8.4%. ⋅ For a mill speed of , the lowest specific power occurs for new lifters.
The rod mill motor power is in horsepower at the mill pinion-shaft. For different length rod mills power varies directly as rod length. For difference between new and worn liners increase power draw by 6%, and adjust for bulk density per Table A. Wet grinding rod mills are normally used in minerals processing plants.

If the ball mill is too short, it will fail to complete the specified grinding fineness, while if the ball mill is too long, it will increase power consumption and produce over-grinding. In production, the ratio of length to the diameter of most ball mills is in the range of 0.78-2. Speed of ball mill
Cement ball mill is mainly used for circle flow grinding system, and it has the characteristics of high efficiency, big capacity, and low power consumption, especially for cement slag. Compared with traditional ball mills, it can increase 15-20% of capacity and 10% of electricity, otherwise, the temperature of final products can lower than 20 ...
Abstract: In determining the proper mill size required to meet a targeted production rate, many factors are evaluated including: length to diameter (L/D) ratio, individual compartment lengths, rotational velocity, liner type, ball gradation and percent filling degree. This paper examines the effects of changing mill filling degree with respect to specific power consumption (kWh/ton) and ...

Mathematical models are presented which describe the power consumption in agitated ball mills in absence of grinding beads. In addition, tests with grinding beads filling were also performed, leading to scale‐up guidelines with respect to power consumption. Finally, the influence of size and material of grinding beads was investigated.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
Power Consumption in Cement Manufacturing Plant: The cement industry, as a traditional high power consumption industry, power consumption in the cement grinding process takes a large ratio in the whole production, electric power consumption is about 60%-70% of the total consumption.
Grate Discharge Ball Mill: This type of mill usually works with a high circulating load and thus produces very little extreme fines. The specific power consumption is therefore less than for an Overflow Mill. A Grate Discharge Mill will also have 15—25 % higher capacity per volume unit as compared with an Overflow Mill.
