4. Ball mill rotating speed: when grinding ball adding rate remains constant, the useful power of ball mill varies with the rotating speed, therefore, production efficiency will also be influenced. Ball mill rotating speed need to be adjusted according to different types of ores.
Ball mill. A typical type of fine grinder is the ball slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
All operating parts ( grinding discs, spacers, ball separators and the intake rotor) have been designed to slide over the shaft in any required configuration. This feature provides great flexibility in design, optimizes energy consumption, milling efficiency and maintenance costs.
