Control systems based on fuzzy logic are suitable for illdefined processes in the continuous process industry such as the cement industry (Wang, 1999; Bose, 1994). For future studies, we plan to analyze similar data for the control processes of raw meal grinding, finish cement grinding, and clinker kiln calcination.
Ball mill control Automatic startup control In most cement plants, start up of a mill is conducted through a series of manual operations on the part of an operator. The operator switches on the mill, starts the mill feed and, after ascertaining that the mill load becomes stable, changes the control mode to the constantvalue feedback ...
High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% 10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.
Step 2: Mixing. The second step in the process of cement brick manufacturing process is 'mixing'. In this step, the accurate procedure has to be followed to avoid the formation of lumps hence this should be completely spread all over the surface. Hence cement, water, and concrete should be thoroughly mixed.

Step 4:Cement grinding and storage. Clinker and gypsum for Ordinary Portland Cement (OPC) limestone for limestone cement, and slag for slag cement are all extracted from their respective hoppers and fed to the cement mills. The ball mill grinds the feed to a fine powder in two chambers, namely the first and second chambers.
There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement).
The separator controls the product sizes from 400 to 40 μm. The moisture of the mill feed (cement raw material) can amount to 1518 %. The fineness of the mill product can be adjusted in the range between 94 and 70 % passing 170 mesh. Capacities up to 400 t/h of cement raw mix are recorded .
