Open and closed circuit dry grinding of cement mill ...

2004-1-14  The maximum fineness attainable by open circuit stirred mill tests is 6200 cm 2 /g. #x02022; During the open circuit tests, specific energies excessively increases beyond Blaine values of 4500 cm 2 /g which corresponds to a specific energy consumption of 60 kW h/t. Beyond this point, further grinding can be obtained for the speeds above 600 rpm.

Reasons for unqualified discharge fineness of Ball mill ...

“Coarsening” of ball mill is an abnormal phenomenon that the fineness of grinding products is significantly coarser and difficult to control. It generally occurs in double bin open circuit tube mill with small length diameter ratio. Coarsening of the ball mill will increase the energy consumption of the ball mill, cause waste, and large particle size will also affect the subsequent sorting.

Working Principle of Ball mill: As the mill rotates, steel balls work to grind the materials. The mill rotates approximately once every couple of seconds. The grinding system uses either 'open circuit' or 'closed circuit'. In an open circuit system, the feed rate of materials is adjusted to achieve the desired fineness of the product.
