Ball mills for cement raw material and coal equipped with a drying compartment adequately air swept with hot gas (2.5-3.5M/sec above the ball charge), can handle moisture about 8%. Fully air- swept mills (5-6M/sec) can dry up to 12-14% moisture. Grinding Operation Objectives and KPIs: Highly energy intensive unit operation of size reduction in ...
Advantages of dry grinding: Lower wear rate of mill liners and grinding media. Higher percentage of fines in mill product. In many cases this is very desirable. Target Grind Size. Another factor in choosing a grinding mill is the consideration of the feed size introduced into the mill, and the product required from the mill or mill circuit.

Re: how to estimate the wear rate for Ball mill. Hey; Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated.

A cement grinding mill "A" with a capacity of 50 tons per hour utilizes forged steel grinding balls costing P12,000 per ton, which have a wear rate of 100 grams per ton cement milled. Another cement mill "B" of the same capacity uses high chrome steel grinding balls costing P50,000 per ton with wear rate of 20 grams per ton cement milled.
Then in ball-wear formula (25), T = 6.9/K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = 6.9Wt/Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/6.9Wt are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.
Typically, it is best to start with a 30grit White disc (hard bond) and assess the wear rates and concrete grind as you progress. If progress is limited, this may be due to the hardness of the concrete, so switch to a 30grit Black disc (soft bond) which will respond better to hard concrete.

The grinding media in the ball mill is required to have great wear resistance and impact resistance. The material to make the grinding media must be hard, wear-resistant, and not easy to crack. Burr and crack are not allowed on the surface of grinding media, and the out of roundness of the steel ball shall not exceed 2% of its diameter.
achieving the lowest operating wear rate (typically from 0.1-0.7g/t). The specific design and equipment required for the mill's drying arrangements are selected by Fives according to the material type to be dried, its grain size and moisture content. The grinding flowsheet can be adapted depending on the application. For wet

2. When grinding cement with varying fineness, closed circuit grinding should be preferred because it is more flexible than open circuit grinding. 3. Cement ground with high circulating load contains fewer ultra-fine as well as fewer coarse particles. 4. Closed circuit grinding yields more advantageous wear rate. 18.

The rate of wear is equal to the amount worn off divided by the time required; but the amount worn off in any interval is 1/6πS (Da³ – Db³). The total weight of the balls in any interval is equal to the number of balls in the interval times the mean weight of these balls,
