However, the unit cost for wear parts for a ball mill is much lower than for a vertical roller mill. For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 EUR per ton of cement.

The final manufacturing stage at a cement plant is the grinding of cement clinker from the kiln, mixed with 4-5% gypsum and possible additives, into the final product, cement . In a modern cement plant the total consumption of electrical energy is about 100 kWh/t . The cement grinding process accounts for approx. 40% if this energy consumption.
The cement mills in the system can be cement ball mills or vertical roller mills. OPC & any other types of cement can be produced in a short period. It is proven that investors can make a profit in 1 to 2 years. Model Plan. Plan 1: 400,000 TPA modular cement grinding plant with ball mills.
The energy consumption of the total grinding plant can be reduced by 20–30 % for cement clinker and 30–40 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended. 2.5.
This should be compared with 40-45% in wet grinding. The expression used for this phenomenon is that the charge in a dry grinding mill is swollen. Big dry grinding ball mills are often two-compartment mills, with big balls in the first compartment and small balls or cylpebs in the second one. An extra grate wall is used to separate the two charges.
Output may increase by 5 – 10% for normal OPC, or more for finer cement. Ball mill improvements Plant & equipment design. o State-of-the-art ball mill o Mill linings o Mill diaphragms ... Of the 4 main mill systems in use for cement grinding, ball mills are by far the predominant, despite a higher energy consumption compared with a stand ...

In addition to wear speed, ball size and recharge practice, charge volume, and feed rate are significant factors affecting the actual production wear rate. Wear speeds are largely independent of ball size and ball charge volume. The wear rate exponent for SAG milling was experimentally determined to be n = 2.8.
