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.

Important advances have been made in the last 60 years or so in the modeling of ball mills using mathematical formulas and models. One approach that has gained popularity is the population balance model, in particular, when coupled to the specific breakage rate function. The paper demonstrates the application of this methodology to optimize solids concentration in …
As a general rule: 1. For over-flow ball mills the charge should not exceed 45% of the mill volume, 2. For grate discharge mills the charge should occupy about 50% of the mill volume. 3.3 Ball Size at Initial Ball Charge. Ball sizes commercially available for charging in grinding mills range from 10 to 150 mm.
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to …

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.
Ball mill is a key equipment for grinding materials. thus grinding ball mills are widely used in the mining beneficiation process, and it has a wide range of suitable grinding mineral and can works on wet and dry grinding processing. our JXSC's ball mills are perfectly used for ores such as gold, iron, zinc ore, copper, etc.

GSI's ball mills are housed with oversized roller bearings and a complete drive system discharging mesh sizes from ~40M to <200M. The capacity, or throughput, of our GSI ball mills are directly linked to the particle size of the ball mill discharge. For instance, it is roughly 3 times as fast to reach a 65 mesh grind than a 200 mesh grind.

The water can wash away the fine particles in time to avoid over-grinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%-10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.
balls and blocking the grate discharge. Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost.
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. This is different to an overflow mill which holds the slurry and balls inside until ...
