The overflow type of Ball Mill is designed to overflow and discharge materials from the trunnion on the outlet side. By combining it with a mechanical classifier or wet-processing cyclone, you are able to extensively use this type for grinding in closed circuit or for special applications such as re-grinding in open circuit
The discharge port may be covered by a grate to prevent oversized ore exiting the mill, or it may have no grate (overflow type ball mill). As the balls wear due to abrasion, they are replaced with new balls (‘green’ balls). If large particle sizes are retrieved from the ball mill, the process is known as a ‘coarse grind’

Overflow VS Grate Discharge Ball or Mill Why Retrofit Allow me to compare: Ball mills can be of the overflow or of the grate discharge type Overflow discharge mills are used when a product with high specific surface is wanted, without any respect to the particle size distribution curve Overflow discharge mills give a final product in an open circuit
Ball Mill Working Principle. To be chosen according to the grinding material, material is composed of a ball mill feed end of the hollow shaft is arranged in the tube body, when the ball mill cylinder rotation time, grinding body due to inertia and centrifugal force, the effects of friction, making it attached to the cylinder liner on the cylinder body away, when taken to the height of a

Overflow type ball mill is a kind of beneficiation ball mill whose name comes from its ore discharge method. The overflow type ball mill is widely used in cement, mineral, refractory material and other industries. According to the discharge method, it is also suitable for the beneficiation industry to grind fine ores or regrind concentrates

Jun 24, 2015 The discharge end of the Grate Discharge Ball Mill has at least ten times the discharge opening area, through the grate slots, compared to the common trunnion overflow type mill. The discharge grates are designed to run clean and free of any blinding or choking. The pulp level in the mill may be varied by merely changing the pulp dilution
Jun 23, 2020 Converting a ball mill from overflow to grate discharge involves installing a grate inside the mill at the discharge end. The grate holds the balls inside the mill but allows the slurry to pass through, and it is then pumped out of the mill by the pulp lifters
The overflow type ball mill can control the grinding time by itself and fully realize the automatic control. Advanced component performance: The overflow discharge ball mill has a short stopping time during the working process, and the machine vibration is small during operation, so the equipment has a long working life. The overflow discharge ball mill has low labor
We recently converted a grate discharge type ball mill (size 5.7X8.6m) to an Overflow type. Before conversion, the ball level was 26%, and we were able to obtain a grind of 90%+ passing 75mic at a throughput of 350t/h. After conversion it’s a nightmare to obtain 90%+ passing 75mic at the same throughput. No change to the cyclones done
Discharge of pebbles, finer rock, ball scats and slurry from mills and its flow through trommels, and into other processing operations has strong impacts on overflow ball mill performance

Jan 01, 2015 However, overflow discharge mills are preferred for their simplicity of design and operation. The overflow mills use much simpler trunnion bearings to support the mill, whereas grate-only discharge mill would require a tire gear around the shell which is expensive and involves complex manufacturing process as the grate has to withstand the pressure exerted by
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

Dec 26, 2019 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
May 18, 2020 The ore discharge of overflow type ball mill mainly depends on the pulp itself high over the lower edge of the hollow shaft bushing. 2. Performance and application differences between grid type ball mill and overflow type ball mill. Compared with the overflow type ball mill, the ore discharge of grid type ball mill is low-level forced discharge

Grate ball mill (grate discharge ball mill) is a ball milling machine used to grind various ores and other materials. Grate type ball mill is a traditional ball milling equipment for forced ore discharge by ore discharge grate.. Its basic structure and grinding process are basically the same as the overflow type ball mill, but the structure of the ore discharge part is different
