Therefore, cement particle distribution is the key part of cement production quality control. When the cement fineness is relatively small, 80 and the sieve residue cannot reflect the grinding condition, so 32 or 45 & M should be used as the quality control standard.

Common Issue: Mill variation affecting kiln stability quickly. For example, if mill product lime CaO or LSF is higher at given time, it appears soon in kiln feed and disturbs kiln operation, instead having blending silo in between. It happens due to short circuiting of material. Strategy to fix the issue:
Kiln pyro control Maintaining optimal levels of O 2 (oxygen) in the process not only removes the risk of explosion, it also prevents a toxic build-up of CO (carbon monoxide). Kiln stop prevention Downtime costs – big time. And if O 2, CO or SO 2 (sulphuric acid) build up in your kiln, production has to be stopped for at least three hours. You

Mill System Operate Safety. When the raw material is running in the vertical mill, the drying heat source of the material comes from the hot gas at the kiln tail. Therefore, when the vertical mill is operated, the control of the inlet and outlet dampers should be balanced by the kiln mill.
The mill was designed for a capacity of 10 tons per hour of the raw material when fed with pieces of 1 in. and under, the residue being 8 per cent. on the 170-mesh sieve. In practice the mill grinds approximately 11 tons per hour to between 9 and 10 per cent. residue …

cement plant, the kiln. Based on their design, it is critical to keep the kiln in motion at all times when heated. The inching drive for this application is designed to operate whenever main power is lost for the rotation of the kiln. The second cement application for inching drives is the rotation of the horizontal grinding mills for maintenance.
