Portland cement is the Cement obtained by intimately mixing together calcarious and argillaceous materials, burning them at clinkering temperature up to about 1450 degree celcious and grinding the resulting clinker (calcined product) at required fineness and finally mixed with gypsum to obtain cement. This cement is a finely ground mixture of
Emission Factor Documentation for AP42 Section 11.6 Portland Cement Manufacturing Final Report pyroprocessing, and finished cement grinding. Each of these process components is described briefly below. The focus of the discussion is on pyroprocessing operations, which constitute the core of a portland cement plant.
Combining portland cement with supplementary cementing materials produces blended cements. The materials are combined by grinding them together as part of the cement manufacturing process or by blending them together after grinding.
grinding conditions associated with fine grinding of cement clinker and related products, enabling a high grinding efficiency and stable operation. Figure 3: H However, despite a generally good performance of vertical roller mills used for grinding of cement and related products the vertical roller mill is still inferior to the ball
MYK Grind 18 is one of the most effective dispersants yet developed for use as a grinding aid for Portland cement and other hydraulic cements. MYK Grind 18 greatly improves the efficiency of the grinding process by reducing the surface energy forces which cause agglomeration of the newly fractured cement particles.

The finished product is collected in a dust filter. The Horomill is a compact mill that can produce a finished product in one step and hence has relatively low capital costs. Grinding Portland cement with a Blaine of 3200 cm 2 /g consumes approximately 23 kWh/t and even for pozzolanic cement with a Blaine of 4000, power use may be as low as 30
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
The Process for Making Portland Cement. Materials that contain appropriate amounts of calcium compounds, silica, alumina and iron oxide are crushed and screened and placed in a rotating cement kiln. Ingredients used in this process are typically materials such as limestone, sandstone, marl, shale, iron, clay, and fly ash.
