For the grinding to start, the floor needs to be given at least seven days to cure. White cement cures faster than ordinary cement and works done using white cement can be grinded in four days. Grinding is done in two phases. The first phase involves rough grinding using Block-stones 8x2x2 rough.Diamond grinding pads can also be used.
Jan 01, 2021 A soft constrained LMPC algorithm is implemented on a cement raw-mix blending process and a cement mill grinding process. The proposed soft constrained LMPC technology can increase the production by 5-10, reduce the energy consumption for cement kilns by 2-4, and improve product quality significantly.
The mixture then sent to final grinding process. For ordinary Portland cement it remains between 3 to 4 and in case of Quick setting cement it can be reduced up to 2.5. Role of Gypsum in Cement The main purpose of adding gypsum in the cement is to slow down the hydration process of cement once it is mixed with water.
