Abstract The results of a detailed study on material flow through a grate-discharge open-end ball mill versus an overflow-discharge constricted-end ball mill are presented to emphasize the effect of discharge-end design on mill transport characteristics. The effect of feed rate to the mill, mill rotational speed and ball load on the residence time distribution of the flow regime, the ...
Reasons And Solutions For The Rough Discharge Of The Ball Mill. The roughness of the ball mill refers to the abnormal phenomenon that the fineness of the mill product is significantly coarser and difficult to control. It generally appears in the double-chamber open-circuit tube mill with a relatively small length and diameter.
The ball mill discharge end liner originally uses 12Mn cast steel, while following problems are found 1It is difficult to repair the liner of high hardness and cast steel with low precision. During installation, a gap is formed between the mill end cover, while the material will wash out the mill end cover and leak the slurry due to the mismatch.
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.,

ball mill, ore grinding machine, ore ball mills, China ball mil. Due to the ways of discharge are different, there are two types of ball mills into-lattice type and over-flow type, or center-discharging type and side-
The auxiliary grinding bodies are transported into the agitator ball mill and out of the latter via a closed circuit by means of a hydraulic conveying medium. Hydraulic milling ball feed and discharge for stirred ball mills
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter Figure 8.11. The feed can be dry, with less than 3 moisture to minimize ball coating, or slurry containing 2040 water by weight.
Steel Ball Mills amp Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800s. The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media ceramic or
2. Dry Type Ball Mill Some discharge materials are extracted by air flow, and the mill and wind grading device are closed-circuit. For example, cement mill adopts automatic discharge. 7 Types on the Basis of Cylinder Direction. 1.

Jun 24, 2015 Grate Discharge Ball Mills have shown 25 to 45 more tonnage ground and a substantial reduction in power consumed per ton of material compared size for size with overflow mills. To illustrate the characteristics of various type mills we have shown the types of discharge for rod mills and ball mills. There are essentially four types of rod mill ...
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. This is different to an overflow mill which holds the slurry and balls inside until ...
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.
