Ball Mill: Operating principles, components, Uses ...Traduire cette page

    Ball mills grind material by impact and attrition. The degree of milling in a ball mill is influenced by; a. Residence time of the material in the mill chamber. b. The size, density, and number of the balls. c. The nature of the balls (hardness of the grinding material) d. Feed rate and feed level in the vessel. e. Rotation speed of the cylinder. Several types of ball mills exist. They differ ...
