We use a closed-circuit grinding process to obtain a very finely ground cement. A size particle range of 3 to 30 microns (one micron is a thouh of a millimeter!) results in the most efficient hydration of cement and better strength properties, including more late strength. The Wonder Cement factory process is now complete.
begun in the mixer. The grinding operation is per-formed by passing the paint through a series of rollers under great pressure. In some cases the mixing and grinding operations are performed in one operation in what is called a 'pebble mill". This consists of a revolving cylinder containing hundreds of steel or porcelain balls which

Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness. In addition, some products (usually referred to as performance enhancers) provide positive effect on cement hydration improving strength development [1].

In California, the cement industry consumes approximately 1,600 GWh per year, 220 MW, and 22 million therms per year. This represents about 5% of California manufacturing electricity consumption and 1% of California manufacturing natural gas consumption. Table 2-2 compares cement industry electricity and natural gas use for California and the U.S.

Normalisation Methodology for Cement Sector 31 The Production during commissioning of New Process Line/Unit is to be subtracted from the total production (Clinker) of plant and added in the import of intermediary product (Clinker) (ii) Thermal Energy Consumed from external source due to commissioning of New Line/Unit till it attains 70%
The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time
