The rod mill uses steel bars as the grinding medium, and the materials are in point contact during the grinding process. Therefore, compared with the energysaving ball mill, the rod mill has the characteristics of uniform ore discharge, which is suitable for production lines that require more uniform particle size, such as the rod mill grinding quartz sand, sand making and other production lines.
Key Differences: Geometry: The primary difference lies in the geometry of the grinding chambers. Tube mills have a longer cylindrical structure with a smaller diameter, while ball mills can have a ...
Sand mills are vertical bead mills which are used for particle size reduction and dispersing of pigments in liquids in the paint, ink coating industries. Particle size reduction upto 2 microns is possible in a single pass. The material to be processed is pumped from the bottom of the mill into the milling chamber which is filled with ...
The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where ...
A slight difference of condition between the two cases, however, is that with dry milling the fluid (air) fills the whole of the mill shell not occupied by the balls, whereas with wet milling the liquid occupies only a part of the mill volume not occupied by the solid charge. This difference would be expected to have some slight effect on the ...
