Raw Mill In Cement Plant,Cement Making Plant

This paper mainly introduces the raw mill in cement plant. In order to achieve the desired setting qualities in the finished product, a quantity (2-8%, but typically 5%) of calcium sulfate (usually gypsum or anhydrite) is added to the clinker and the mixture is finely ground to form the finished cement powder. This is achieved in a cement raw mill.

Analysis of Raw Mill Machines Maintenance in Cement

Cement processing plan is a state-owned enterprise engaged in the cement industry. The problem that this factory has is such as frequent damage to the engine. The machines used in cement production at the factory include raw mill machines, kiln machines, and cement mill machines. The more often a machine is damaged, the average time between failures of a machine is lower.
