xxxx says Ball Mill Diaphragm Slots Dear All Why the slot size of diaphragms in a two cahmber bal mill is 8 to 10mm in I chamber 6 to 8 in II chamber? The slots in the diaphargm plates can be horizontal or vertical ? What is the logic for horizontal direction or vertical?
An intermediate diaphragm separates both compartments from each other. The 1. compartment is filled with coarser balls and lifting liners and is supposed to pre grind coarser particles. The 2. compartment is the fine grinding chamber and is equipped with a finer ball charge and classifying liners.
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles ...
