Economics Q A Library A cement grinding mill A with a capacity of 50 tons per hour utilizes forged steel grinding balls costing Php12,000 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 Php50,000 per ton with a wear rate of 20 grams per ton cement milled...
15/ For all dry cement mills but without Slag, the ball wear rate do not exceed 40 g/tons of ground material. If this wear rate is exceeded and the cause is found by independent investigator to be due to defectives, then product are replaced at our cost 16/ The warranty period after products have been received and inspected by end user is 12 months
According to statistics, the power consumption per ton of cement production is no less than 70 kW / h, but the effective utilization rate of this part of electric energy is very low. In order to improve the output of the cement ball mill grinding system and reduce energy consumption, we have done some researches and analysis and finally, find ...

Grinding media consists balls of 3-4 sizes (60mm-30mm) in designed proportions with large sizes in feed end and small sizes in discharge end. About 27 to 35 % volume of mill is filled with grinding media. Equilibrium charge is that charge where compensation for wear can be done by balls of one size only usually the largest size in the compartment.
reduction of wear rates and improvement of efficiencies relating to grinding and crushing operations in the Global Cement, and Mining industries and also in the Thermal power plant segment in India.

Economics Q&A Library A cement grinding mill "A" with a capacity of 50 tons per hour utilizes forged steel grinding balls costing Php12,000 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 Php50,000 per ton with a wear rate of 20 grams per ton cement milled.
Knowing that the loading rate is 13-15 tons, we have determined the range of the grinding balls assortment: 11 tons of 25 mm balls and 2 tons of 30 mm balls. Next (as the grinding balls wear out), the mill needs to be refilled with grinding balls of 30mm. The next refilling of the mill must be carried out by grinding balls of 30mm.

The hardness is stable and fluctuated little, and the wear resistance is very good. The impact energy is 4.7-5j / CM2, the impact toughness is very good, the breakage rate of the grinding ball is less than 1% 3. The ore consumption is 0.23 kg / ton compared with 0.6 kg / ton of forging ball.
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball …
The rate of wear will in the first place depend on the abrasive properties of the mineral being ground and naturally also on the hardness of the grinding media themselves. The wear of rods and balls is usually quoted in grammes per ton of material processed (dry weight) and normal values may lie between 100 and 1500 g/ton.

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.

In addition to Grinding Media, Company is now focusing on Mill Linings for the mining customers. The Company has been making these parts for grinding mills for Cement grinding for more than 20 years. It now offers these parts for grinding mills used for mineral ore grinding and offering solutions which can result in optimized grinding efficiency.
Only a very small part of the energy is transformed into efficient grinding, with the remaining energy channeled into liner and media wear, heat and noise. In terms of technology, there is not much that can be done with the mill itself except for the engine and drive, but it is often possible to control the process better.
