Cement is a crucial building material used in construction. The Cement manufacturing process involves the extraction and preparation of raw materials, such as Limestone, clay, shale, iron ore, and Gypsum. These materials are crushed, ground, and blended to form a raw meal, which is then heated in a kiln at high temperatures.

1. Introduction. Cement grinding is a key process in the cement industry. During this phase, gypsum and mineral or artificial raw materials (eg pozzolan, ash, limestone) are added to the clinker (basic raw material for cement production) and, then grinded in special mills until a very small grain size is achieved.
Coal mill is the main equipment in the pulverized coal preparation calcining topgrade cement clinker requires a stable supply of coal powder as the fuel of cement kiln, and more than 85% of pulverized coal should be finer than 200 mesh, water content less than 2%, and calorific value more than 6000Kcal/kg, therefore the pulverized coal preparation system is one of the ...

According to Indonesian Standard SNI, Portland Composite Cement (PCC) or blended cement is defined as a hydraulic binder which consists of clinker, gypsum and one or more inorganic materials where their contents range from 6% to 35% of the total mass of PCC. However, some factories still have their clinker levels in PCC above 80%.

Power requirement is very high. Speed control ratio is 1:10. Very low creeping speeds of 1 rpm may be required. Starting torque should be in the range 200 to 250% of full load torque. The acceleration of the drive should be completed in about 15 s. For small periods an overload capacity of 200250% may be required.
Milling operations in various production processes are among the most important factors in determining the quality, stability, and consumption of energy. Optimizing and stabilizing the milling process is a nonlinear multivariable control problem. In specific processes that deal with natural materials (, cement, pulp and paper, beverage brewery and water/wastewater treatment industries).
