open circuit to closed circuit ball mill design in

The batch ball mill is a kind of ball milling machine which discharges the material in one time according to the nature of the material. Different from continuous ball mill, batch type ball mill grinds powder by times and adopts intermittent operation. The batch mill is mainly used for the mixing and grinding of materials, with uniform product fineness and saving power.

Ball Mill Explained saVRee

If rods are used instead of steel balls, the mill is referred to as a ‘rod mill’. Closed-Circuit or Open-Circuit. Ball mills may operate in a closed-circuit, or open-circuit. Closed circuits return a certain amount of the ball mill’s output back to the ball mill for further size reduction.

The cement mill

Grinding systems are either 'open circuit' or 'closed circuit.' In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding.

How to Choose Open circuit Grinding or Closed circuit

Jan 15, 2020 Therefore, the rod mill has the ability to control the particle size and can be used as an open-circuit grinding equipment. Although the ball mill does not have the ability to control the particle size itself, it can control the particle size with the help of the classifying equipment. The mill will discharge ore into the classifying equipment.
