cement mill operations in four ways: • More consistent quality (grade). The continual monitoring of the mill loading and the adjustment of the feed and separator results in reduced variations in cement grade. This has the added benefit of a more consistent product quality. The control strategy is designed to respond to disturbances in the

Grindability of a 95/5 OPC at various Blaine fineness: o 27-32 kWh/t at 3,000 cm²/g. o 39-47 kWh/t at 4,000 cm²/g. o 58-69 kWh/t at 5,000 cm²/g. Every 100 cm²/g increase in cement fineness increases the mill power consumption by 1-2 kWh/t for a closed circuit mill & 2-3 kWh/t for an open circuit mill, a sheer waste if this is not required ...

Methods and systems for controlling a cement finishing mill, and operating the mill at an optimal point, are disclosed. To determine an optimal point of operation, values of mill power and sound are collected and compared to values predicted by a model to determine if the mill is choking. This choking determination is used in one of two processes to …

Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds. The drum is generally divided into two or three chambers, with different ...
