12-12-2016· If P is less than 80% passing 70 microns, power consumption will be. 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 distribution of 80% passing ¼ inch (6350 microns).

Industrial ball mills can be as large as 8.5 m (28 ft) in diameter with a 22 MW motor, drawing approximately 0.0011% of the total world's power (see List of countries by electricity consumption). However, small versions of ball mills can be found in laboratories where they are used for grinding sample material for quality assurance.

Ball mill of each type of machine, its capacity is determined, before starting, we need to adjust the various parameters according to the determined capacity and finished product requirements, if the feed If the amount is too large or too small, it will cause waste of electricity in production, which will naturally increase the consumption of

Calculation of energy required for grinding in a ball mill. Int. J. Miner. Process., 25: 41-46. The Bond work index, Wi, as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding product.

The surface area, size distribution and specific energy consumption for the material ground in the ball mill were used in conjunction with the single-particle data to provide an assessment of the energy efficiency of ball milling.

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.

mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential

10-2-2016· re VRM vs Ball Mill for Cement Grinding. Specific power consumption- high for ball mill and Low for VRM ; Maintenance costs- high for VRM and low for Ball mill ; Process control/process technology- ball is operation friendlt and simple in operation but VRM requires some PID or

The amount of power consumption depends on the quality of materials and rotating speed of ball mill. The active power consumption is more than 70% of the whole power consumption. The second is reactive power consumption, which refers to the power consumption of the ball mill itself. It accounts for 5-10% of the whole power consumption.

Ball Mill Machine Structure Ball Mill Ball Mill machine is composed by feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control). The quill shaft adopts cast steel part and the...

In other words, Tdp is the saturation temperature of water corresponding to the vapor pressure: Tdp = Tsat @ Pv 8.0 Cement Mill Specific Power Consumption: A cement mill is usually limited by drive power so that any reduction in kWh/t translates in to increased production capacity as well as a reduced unit power
