A motor with around 1400 Horse Power is calculated needed for the designed task. Now we much select a Ball Mill that will draw this power.. The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the matching mill required to

Calculating a grinding circuits circulating loads based on Screen Analysis of its slurries. Compared to Solids or Density based Circulating load equations, a more precise method of determining grinding circuit tonnages uses the screen size distributions of the pulps instead of the dilution ratios. Pulp samples collected around the ball mill or rod mill and hydrocyclones, screen or
The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters 10 feet diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S. Rod and Ball Mills by C.A. Rowland and D.M. Kjos AllisChalmers
BallRod 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. This fact should be carefully kept in mind when determining the capacity of a Steel Head BallRod Mill, as this unit can carry a greater
BALL MILL GEARBOX PROBLEM BACKGROUND INFORMATION amp OBSERVATIONS Concern was expressed over the gearbox and Ball Mill at a power plant. Black grease was noticed at the couplingend pillow block bearing as well as a loose bearing nut. Unusual noises were also reported from the machine.
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser works on the principle of impact and attrition size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati
Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum 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 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, semiautogenous 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

The ball mill has higher circulation load, it generates only 30 35 of actual fines you require to be called as product. If your product size needed is 100 passing 45 micron, then the ball mill total discharge material will contain normally 30 of 45 micron. The rest is oversize which has to be ground again.

Pulverizer or inother name Mill used for pulverized coal boiler of thermal power plant. The device pulverize coal to powder pulverized coal before blowing to burners of furnace.
The ball and tube mills are lowspeed machines that grind the coal with steel balls in a rotating horizontal cylinder. Due to its shape, it is called a tube mill and due to use of grinding balls for crushing, it is called a ball mill, or both terms as a ball tube mill. These mills are also designated as an example size, BBD4772,
