This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,

Vibratory ball mills use high-frequency vibration to make grinding media in the cylinder produce inertial impact force. Raw materials are ground under the impact. The grinding media is usually φ16~φ36mm steel ball or steel rod. After carburizing and quenching, their hardness can reach above HRC55.

Ball mills are usually either of the grate (diaphragm) or overflow type. Ball Mill Components. Ball mills consist of the following components: Inlet – crushed ore is fed to the ball mill through the inlet. A scoop ensures the feed to the mill is constant. Discharge – reduced feed exits the mill through the discharge. Ball Mill Components

ore per day in six overflow ball mills. The concentrate is transported to a smelter a few miles away. The crushed ore from primary and secondary ores is conveyed into bins. The ore from the bins is fed into the ball mill using a conveyor belt. The ball mill grinding circuit is illustrated in Figure 2. % Solids 78.9 Circulating Load 474% Advance ...

Overflow ball mill is also called overflow type ball mill. It is a kind of wet ball mill grinder, frequently used in the material refine grinding (finished material is lower than 0.2mm) or the second stage grinding.Overflow ball mills adopt the overflow principle to discharge the qualified material slurry higher than the discharge port naturally.

Overflow Ball Mill are generally used to grind materials with 1/4 inch and finer to the particle size of 20 to 75 microns. In order to achieve reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reground.

Overflow Ball Mill. The structure of the feed end and the inside of the overflow ball mill is the same as that of the lattice type, but the discharge end is different. The overflow head of the overflow ball mill is the same as the normal end of the normal liner (end liner) without the boring. The direction of the spiral in the discharge port is ...

Wet overflow ball mill. The main component of wet overflow ball mill is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. Materials are put in cylinder through the feed opening and then thoroughly grinded. The falling course of iron balls and ores can produce huge falling impact and autogenous grinding.

1. Overflow type: discharge ore through the hollow shaft. When the ore discharge surface is higher than the slurry surface, the finished product is discharged and the ore is automatically discharged by gravity, thus the overflow ball mill saves energy. 2. Grate discharge ball mill: the ore is discharged through the grate plate.

The effect on overflow ball mill power draw of the minor changes attributable to the increased feed rate may be different to that on an AG/SAG mill. For an overflow ball mill, the increased slurry pool volume resulting from the increased mill feed rate will not lead to an increase in ball mill power draw; rather more often the opposite.
