The raw material preparation system of the 2 500 t/d cement production line can adopt the vertical mill with the disc diameter of 3 400 mm as the main grinding machine. When the grinding particle size is less than 60 mm, the fineness of the finished product is 16%, and the moisture content of the finished product is 0.5%.

Efficient particle size reduction: Wet grinding can reduce particles to a smaller size compared to dry grinding. No dust: Wet grinding does not produce dust, which reduces the risk of contamination and improves worker safety. Cooling effect: The liquid used in wet grinding acts as a cooling agent, which prevents thermal damage to the material.

There are still many ball mills in use for cement grinding in North American. Functionally, the job of a finish mill feeder is the same as a raw mill feeder – minimize false air passage into the mill: the airlock function. Finish mill feeders must handle large throughputs, 100-500 tons per hour rates are common.

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. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, i.e. whether hardfacing is applied.
