After writing your SOP document, review and test it with other team members before sending it to stakeholders for approval. Once it gets approved, it will then be implemented and shared across relevant employees.

The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction. Clinker quality depends on raw material composition, which has to be closely monitored to ensure the quality of the cement.

29. Standard Operating Procedures (SOP) Manual for Calibration Department. 30. Standard Operating Procedures (SOP) Manual for Maintenance Department. Production Process: Mining of raw material is the first step involved in manufacturing cement. Limestone and clays are mined using drillers and they are blasted to break their huge size.

Open barren solution shut off valve to ball mill. Open gland water valve to the appropriate cyclone feed pump. Put density controller on MANUAL mode and set the output to 20%. Set the setpoint to 50-55% solids. Start the appropriate cyclone feed pump.

Cement Manufacturing Process Phase 1: Raw Material Extraction. Cement uses raw materials that cover calcium, silicon, iron and aluminum. Such raw materials are limestone, clay and sand. Limestone is for calcium. It is combined with much smaller proportions of sand and clay. Sand & clay fulfill the need of silicon, iron and aluminum.

Further same procedure should be applied for other machine. M3 required maximum period. M3 ≥ M5 +M4 ≥ M2 + M6 + M1+M7 First enter the activity of a machine which required maximum time as per sequence. Then place other dissenting order machine or group. If the activity is foul then place in other column. B4 fouls C7 hence placed in next shift.

Cement manufacturing: components of a cement plant. This page and the linked pages below summarize the cement manufacturing process from the perspective of the individual components of a cement plant - the kiln, the cement mill etc.. For information on materials, including reactions in the kiln, see the ' Clinker ' pages.

The mill should rotate in the proper direction. The mill gear should be lifted by the pinion causing a downward pressure on the pinion shaft bearing. Mills are made either right or left "hand". There are two methods of identifying the "hand" of the mill.
