CL Attritors – Stirred Vertical Ball Mill Limestone Grinding System The economical CL Attritor Stirred Vertical Ball Mill is used for wet grinding limestone for flue gas desulphurization. The process uses limestone feed stock of approximately 6mm in size and wet grinds the limestone to 95% minus 325 mesh. The CL Attritor operates in continuous
2 Grinding process description The ball mill grinding process is mainly composed of a ball mill, a hydrocyclone cluster, a sump, a slurry pump and an ore bin. The schematic diagram of this process is shown in Fig. 1. Fig. 1 Schematic diagram of ball mill grinding process. The variables of this process shown in Fig. 1 are ex-plained as follows: W
High Pressure Grinding Rolls (HPGR) is rarely considered as lateritic bauxites are too soft to warrant this technology. Only for hard diasporitic bauxite, where digestion feed sizes of P80 -75 µm are required would it ever be considered. Rod and ball mills can readily handle bauxite on account of its very soft nature. However, it is the ...
The BAM ball mill for industrial minerals is designed to be particularly efficient thanks to our process know-how. This is because the efficiency of a mill depends on its internals. All parts of the mill, the diaphragm, the shell lining and the ball charge, have been continuously developed in-house for nearly a century, which is the basis of ...

Tube Mills: Tube mills are similar to ball mills but have a longer horizontal cylinder for grinding clinker. They are used less frequently than other grinding equipment in the cement industry. Air-Swept Mills: Air-swept mills use air to transport the clinker and grind it within a closed circuit. These mills are energy-efficient and can produce ...
Cement Ball Mill Structure. When Ball Mill is working, raw material enters the mill cylinder through the hollow shaft of the feed. The inside of the cylinder is filled with grinding media of various diameters (steel balls, steel segments, etc.); when the cylinder rotates around the horizontal axis at a certain speed, Under the action of centrifugal force and friction force, …
Table 1. Chemical composition of typical grinding media (% wt.). Adapted from [24]. 2.1.1. Cast Iron Cast iron can be grey cast iron or white cast iron, but white cast irons are commonly used in ...
When the cylinder of the ball mill rotates, the grinding body is attached to the liner of the cylinder and taken away by the cylinder due to the action of inertia, centrifugal force, and friction. When brought to a certain height, it will be thrown down due to its own gravity, and the falling grinding body will crush the material in the ...
