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 ...

WhatsApp: +86 18838072829The mill speed is one of the vital parameters in ball mills, which is normally specified as a fraction of critical speed. It determines whether the load behavior is predominantly the cascading regime, the cataracting regime or the centrifuging regime. In general, the industrial ball mills rotational speed operates at 70%~80% of critical

The Overflow Discharge mill is best suited for fine grinding to 75 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 250 microns.; The CenterPeriphery Discharge mill has feed reporting from both ends and the product discharges ...
WhatsApp: +86 18838072829The study showed that the combination of the BPR and powder type affects the particle size result. The optimum of BPR at 12 with the number of balls is 60 pieces, and the filling rate is %. The result shows that the horizontal ball mill able to grind the calcium carbonate to a size of smaller than 100 mesh (149 µm).
WhatsApp: +86 18838072829Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature. However, the major benefit of using ball mills is the product fineness they can deliver.
