But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.
Feb 08, 2021 The rod mill is generally more efficient than the ball mill due to its more effective cascading action and the greater bearing surface offered by the rods. This means it can operate at lower speeds and with less grinding agents and producing less undesirable slimes byproduct.
Ball mill is a essential equipment for further grinding the material after it is crushed. It continues to grind minerals by grinding media to reach a certain fineness to achieve a better grinding effect. Most of mines use overflow ball mill. The mineral will gradually flow to the discharge end with the rotation of the cylinder and the movement ...
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.
