re amount of material present in kg at any instant in a close ckt ball mill. Dear Chari . In my openion if the circulation factor is 2 with 100 tph product than retention time should be. 6.7*250/300 = 5.58 minutes. Corresponding material inside the mill. 5.58*300/60 = 27.9 t . It is ok ,matching with the end result of 27.9 t.

The optimal retention time depends not only on the feed material and the desired comminution result but also on the ball charge filling ratio and particularly on the L/D ratio. On the basis of the present results and considerations, a specific optimisation of ball mills in semi-finish-grinding plants can be done.

Ball mills Ball mills are essentially fine grinding units capable of grinding material to a fineness say 84% passing 90 microns. The size reduction technique involved here is attrition and impact. In ball mills, Hi-chrome steel balls are used to grind the raw material. The ball mill is located horizontally rotating about the horizontal axis.

Know Process of Ball Mill (Continuous) Heavy duty, continuous type ball mill is with three compartment and screen. Replaceable Liners are fixed inside entire mill. Liners material and shape is selected based on material to be grind. Input material is fed in two primary grinding compartments.

Ball mills are most commonly used in cement factories to grind the raw material and finely grind the cement. The use of ball mills in cement grinding is due to several factors, among which are relatively simple design and high processing rate. However, these machines have certain limitations as well.

It is for grinding Ceramics, Cement, Pencil, Paint, Chemical, Ink, Marble, Coal, minerals etc. About Continuous Ball mill: Heavy duty, continuous type ball mill is with three compartment with screen. Replaceable Liners are fixed entire mill (inside). Liner material and shape is selected based on material
