Ball mill Wikipedia
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 pebblesmain technical parameters ball mill sag Ultrafine Mill According to the principle of material layer grinding, the LUM series of vertical ultrafine mill materials have short residence time in the grinding mill and less repeated grinding, so the iron content in the product is very small and the whiteness and purity of the product are highball mill main technical parameters
