How to Effectively Control the Grinding Fineness and

For many mineral processing plants, tocontrol of grinding fineness and increase the recovery rate of ore concentrateis an important factor to increase enterprise benefit. So how to effectivelycontrol the grinding fineness, we must first fully understand the factors whichaffect the grinding fineness. 1.


2017-6-9  posit Veliki Krivelj, the grinding fineness since the opening of the mine in 1982 has been maintained at values around 58% -0.074 mm. Since then, the operation descended into the deeper parts of deposit, the copper content decreased in the ore and it was assumed that the optimal fineness of ore grinding was changed.


Mining ores first by the jaw crusher, preliminary broken in broken to a reasonable fineness via hoist, after to ore machine evenly into the ball mill, the ball mill for ore smash, grinding.

Ball Mill: Is the Grinding Fineness the Finer, the Better

2018-11-7  In terms of grinding fineness, Xinhai Mining's technology experts also pointed out that grinding fineness is usually determined by the beneficiation test to determine an optimal grinding size range. Generally, the grinding product of the ball mill is mainly measured by screening. The more the percentage under the screening, the finer the grinding.

The Grinding Fineness- the Factor Affecting Gold

2020-3-25  Grinding fineness refers to the thickness of the grinding product, and is usually expressed by the mass fraction (%) of the ore particles less than 200 mesh (less than 0.074 mm) in the total grinding product. In general, the determination of grinding fineness is related to embedded relationship of the ore.

Grinding Fineness Affecting

2.Factors Affecting Grinding Fineness and Improvement Methods The above experiment can determine that a 325 mesh accounted for 95% is a more suitable gold leaching grinding fineness. However, in the actual gold leaching operation, the grinding fineness will also be affected by other factors, which will indirectly affect the gold leaching results.

Indicators and Influencing Factors of Grinding and

2020-2-17  1. Grinding fineness of grinding mill. Generally, use standard screen (200 mesh) to screen the product fineness and count the percentage of the product in the total. For example, when the grinding fineness -200 mesh accounts for 50% or -0.074mm accounts for 50%, the higher the percentage, the finer the product.

Grinding Mineral Processing

The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding, the smaller the particle size. Separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the grinding fineness required for flotation.

How to Deal with the Uneven Fineness of the Grinding

Once the grinding rolls and rings are worn seriously, the grinding fineness of the equipment will be affected.
