Gypsum/Anhydrite for cement manufacture is supplied in crushed form for further fine grinding with cement clinker. When Gypsum (CaSO4,2H2O) is ground to a powder and heated at 150° to 165° C, three-quarters of its combined water is removed producing hemi-hydrate plaster (CaSO4,1/2H2O), commonly known as the 'Plaster of Paris'.

Cement ball mill is a kind of cement grinding equipment commonly used in cement plants. It is mainly used for grinding materials in cement clinker section. Cement ball mill is widely used in cement production, silicate products, new building materials, refractories, fertilizers, black and non-ferrous metal mineral processing, glass, ceramics, and other industries.
CHRYSO® Grinding Aids improve clinker grinding efficiency. This allows for a shortened cement retention time in the mill which, in the end, leads to significant energy savings for each ton of cement produced. • Maintenance cost reduction Shortened cement retention time in the mill leads to a less intensive
Clinker grinding aids. Gypsum is added to clinker primarily as an additive preventing the flash settings of the cement, but it is also very effective to facilitate the grinding of clinker by preventing agglomeration and coating of the powder at the surface of balls and mill wall.

and alumina. Finished cement is produced by finely grinding together around 95% cement clinker with 5% gypsum (or anhydrite) which helps to retard the setting time of the cement. The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone.
Portland cement is the basic ingredient of concrete, mortar and plaster which consists of a mixture of oxides of calcium, silicon and aluminum. Portland cement and similar materials are made by heating (about 1350–1400°C) limestone (a source of calcium) with clay and then grinding this product (called clinker) with a source of sulfate (most ...
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...
Production of Portland cement is a complex technological process that consists of two basic steps. In the first, through heat processing entering raw materials are fundamentally altered creating cement clinker. In the second, by grinding and milling clinker wit gypsum the final product – cement – is manufactured.

The clinker is then cooled and ground to a fine powder in a tube or ball mill. A ball mill is a rotating drum filled with steel balls of different sizes (depending on the desired fineness of the cement) that crush and grind the clinker. Gypsum is added during the grinding process to provide means for controlling the setting of the cement.
The grinding costs of clinker are smaller than this cost difference. Furthermore, if clinker is imported then several types of cement can be produced from that clinker, allowing greater flexibility to meet the specific and possibly changing local market demands. Finally, with a grinding plant, additional efficiencies can be obtained by ...
Clinker preparation stage: it uses XPCF fine crusher to crush materials in smaller size, ring hammer crusher to crush raw coal which is the heat producer. 3. Clinker grinding stage: it adopts DPX crusher to crush plaster and cement clinker is pre-milled by roller press, hammer–mill crusher and XPCF crusher and then grinded by flour mill.
Tanzania: Huaxin Cement has commissioned the grinding system at its Maweni Limestone plant near Tanga. The China-based company acquired the company from Athi River Mining (ARM) Cement in mid-2020. It then invested US$145m on an upgrade to the unit and started trial clinker production in June 2020.
The process of clinkerization signifies conversion of raw meal into clinker minerals mainly consisting of C4AF (Aluminoferite), C3A (Aluminite), C2S (Belite) and C3S (Alite) phases along with small percentage of free lime CaO, MgO, Alkalies, Sulphates etc.
