Optimization of cement grinding using standard bond grinding calculations based on population balance models is successfully applied [4, 38]. Various grinding laws, energy relationships, control factors and controller design for cement grinding are discussed in [37]. Figure-1. Vertical roller mill for cement grinding [13].

Cement Silo. Common Issue: Coating in cement Silo. It happens due to storage of cement in silos at high temperature (>70 o C), and improper water spray system in cement mill. Strategy to fix the issue: Use cement coolers if cement temperature is higher than specified. Do not store cement for long time in silo.

The optimum cement flow rate is found from the contour plot and 3D surface plot to be 47.239 tonnes/day at CaO flow rate of 152.346 tonnes/day and the …

3 In the raw mill, the material chunks are ground finer to allow high-quality blending. As the raw mill is one of the biggest energy consumers in the cement process, it is important to adjust the grinding plant in order to minimize energy losses. 4 It is essential to use a process automation system to optimize the mill process, which in turn mini-
