In this study, the problem related to the under-capacity performance of coal mill at Portland cement plant from Negeri Sembilan Cement Industries Sdn. Bhd. (NSCI) company in Perlis will be addressed. The inefficiency of filter bag house at coal mill is viewed as one of the reasons for this under performance.

Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. Closed circuit ball mill with two compartments for coarse and fine grinding and a drying compartment with lifters are generally found in cement plants for raw material grinding.

After exiting the cement kiln, the clinker is cooled and stored. To produce cement, clinker is mixed with a small amount of gypsum and other additives, such as pozzolans or slag. This mixture is then ground in the cement ball mill. The grinding process involves passing the clinker and additives through the rotating drum of the ball mill, …

The design of the raw material grinding system should focus on the energy-saving, vertical mill grinding system because of its power-saving, simple process to become a large cement plant, the use of a ball mill grinding system is no more than two reasons: first, the raw material is difficult to grind, such as high quartz sandstone content, the ...

Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant. There are also various other raw materials used for cement manufacturing. For example shale, fly ash, mill scale and bauxite. These raw materials are directly brought from other sources because of small requirements.
