Ball Mill Power Calculation Example #1. 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). The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine the power requirement, the steps ...
Grinding mills are used extensively in the mining, cement and industries. One of the popular drive designs for g industry in South Africa liquid rheostats, driving a pinion and mill mounted girth reduction gearbox. These mill drives occur in either singl with installed power ranging from 1 to single drive is illustrated in
INTRODUCTION The pinion (Fig. 1) is driving the ring gear of the ball mill. The total power transmitted through the system is 4 MW. The plant had a record of pinion failures over approximately 3 years. Significant production loss and secondary damage to foundations were recorded.
Where N (kW) represented the power of ball mill pinion shaft; K ωb (kW/t) was the power for per ton ball medium; G (t) represented the weight of media loaded in the ball mill. Usually, the power of the ball mill pinion shaft was directly proportional to the motor power of the ball mill, and the correlation coefficient was
Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.
The Copper Mountain ball mills are 7315 mm [24 feet] in diameter and 12040 mm [ feet] long. They are overflow discharge ball mills with inside diameters of 7315 mm [24 feet] and grinding lengths of 11887 mm [39 feet]. Each Ball mill is also driven by two 8,500 horsepower ABB motors.

The details of the ball mill motor are as follows. Power = kW or HP and the speed is 343 rpm. Load calculations (prior to failure analysis) The ball mill can experience failure based on the maximum normal stress theory as the working loads acting in the ball mill is concentrated across the seam of the mill periphery.

Steel Ball Mills Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's. The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media (ceramic or metallic balls or rods ...
Total SAG Motor Power = (ESAG × tonnes/hour) ÷ ÷ (9) The ball mill motor can be sized using a similar equation, but ball mills normally operate at a higher proportion. of their rated power output, use The ball mill gear/pinion efficiency is the same as for a SAG mill. For a.
Ball mills designed for long life and minimum maintenance Metso overflow ball mill sizes range from 5 ft. x 8 ft. with 75 HP to 30' x 41' . and as much as 30,000 HP. Larger ball mills are available with dual pinion or ring motor drives. Our mills incorporate many of the qualities which have made the Marcy name famous since 1913.
