Factors Affect Ball Mill Efficiency There are various factors affect ball mill efficiency, such as properties of raw material, feeding size, size and proportion of grinding balls and so on. And these factors are not mutually independent, they all have effect on each other. Factors affecting the production efficiency of ball mill ...
The breaking performance of the hemispherical lifter and the ladder lifter was poor, because the main pattern of motion was grinding rather than impact breakage. Secondly, the effects of the height–width ratio of the rectangular lifter, the height of the lifter and the number of lifters on the working efficiency of the ball mill were studied.

A uniform discharge from a closed circuit jaw crusher is 200 t/h. The crusher feeds a wet rod mill such that 80% of the crusher product passes a 16 mm screen. The rod mill feeds a wet ball mill at a feed size of 1.0 mm (1000 μm) and produces a product with 80% passing a 150 μm screen. The rod mill is in an open grinding circuit. Determine: 1.
Therefore, large feeding sizes will affect ball mill efficiency. 3. Mineral slurry density: in wet grinding, material pass time, production efficiency and ball mill power are all influenced by mineral slurry density. Generally speaking, the suitable density is close to 80% when feeding size is large and circulating load is .
2019-9-28 · How do you decide between using a ball mill or a rod mill? Many investigators have attributed the selective grinding of rods to line contact. Other things should be considered. In the two pairs of tests shown in table 12 the relative deportment of large balls and small rods in batch wet grinding is shown. The two loads had the same volume.

2019-9-21 · Ball mills are rather inefficient, and typically require 10–20 kW·h of electric power to make a tonne of rawmix. The Aerofall mill is sometimes used for pre-grinding large wet feeds. It is a short, large-diameter semi-autogenous mill, typically containing 15% by volume of very large (130 mm) grinding balls.
Here Are the Differences Between Dry Ball Mill and Wet Ball Mill. Ball mill is common grinding equipment used in the mineral processing plant, it is also the key equipment for grinding after crushing and screening operation. According to the classification of grinding way, the ball mill can be divided into dry ball mill and wet ball mill.
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Mill load is an important equipment index which is closely related to operating efficiency, product quality and energy consumption of grinding process. Due to high dimension and collinearity of spectral data, mill load model has high complexity, poor interpretability and generalization.
SAG MILL GRINDING DESIGN VERSUS GEOMETALLURGY – It is important to note that the Bond Ball Mill Work Index on SAG ground ore is similar to but not the same as a crushed Bond Ball Mill Work Index. It is ~ 7% higher because the SAG mill grinds the softest components quickly and leaves the harder material to be ground in the ball mill.

Under the condition of one stage one opened circuit, the grinding efficiency is lower and the material quality is poor, which far from intended goal, therefore, the owner chose Xinhai wet rod mill, the rod mill has a small conical cap curvature, which make the steel rod takes regular movement in mill, the grinding particle size is more uniform.
Based on the spectrum feature of the shell vibration or acoustic signal, three soft sensor models of mill load, such as mineral to ball volume ratio, charge volume ratio and pulp density are developed, respectively. The proposed method is tested by the wet ball mill in the laboratory grinding process.
