Maintenance in the cement industry is one of the contributor of the production cost and represent typical 15 – 25 per cent of total manufacturing expenditure. Many companies have tried to use standard production methods to control maintenance cost. This is not effective. The maintenance can increase profits in two main ways: decreasing expenses and increasing capacity. Maintenance costs ...

Before cement raw materials are transported into the cement burning kiln, cement raw material blending process is considered as a whole process, thus the grinding process could be seen as part of blending process. For integrity and generality, we consider that the cement raw material blending process includes ball mill grinding process. Then, the mass balance equation of active ingredients SiO

The clinker factor varies from % to %. The results show that the optimal clinker factor is at % with the CGA addition 300 ppm. It can improve the cement fineness to 3848cm2/gr and decrease the sieving R45μ to 10%. In addition, the strength of the cement produced is higher than the standard. The findings show the chemical grinding ...

· For calculation of factor of saturation used Kind formula (1). Value KS K = 92 % indies that clinker is medium grinded, KS K > 92% – easy to grind, KS K <92% – hard to grind. The lower value KS K, the larger the clinker. Typical KS K values in Portland cement clinker are, or 8098%. The value KS K of ordinary Portland cement is 9095% and 9598% of high strength Portland ...
C2 is the correction factor for open circuit grinding and is a function of the degree of control required on the circuit product. The values of C2 are shown in Table 1. Since for the ball mill design we are using 80% passing, the required value of C2 for the ball mill will be equal C3 is the correction factor for mill diameter and is given
Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.

Cement additives are materials added to cement for the optimization of the cement properties and the cement grinding process. Cement additives are classified into different product groups such as grinding aids, strength enhancers and performance enhancers.
· Of the three types of cement production plants in the USA, there are 96 integrated cement plants and 8 grinding plants. Source: For those who are new to cement industry terms, an integrated cement plant is a factory where 2 processes take place – clinkerization and grinding. Clinkerization involves changing limestone to clinkers.
