For fine raw materials such as synthetic gypsum sources the Horizontal Impact Calciner allows direct calcining without grinding. The Claudius Peters Homogenizer, provides better plaster quality whilst the Claudius Peters Rotary Drum Cooler will cool the product from calcining temperatures to required product temperatures for further handling.
Clinker is the most significant component of cement. It determines the strength properties of the final material. Clinker enters the production process in the form of granules. The diameter of the granules varies in the range of 10-60 mm. Heat treatment component is made at a temperature of about one and a half thousand degrees.
The manufacture of Portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, these materials partially fuse to form nodular shaped clinker by broking of chemical …
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.
Cement production. Cement is produced with fine grinding of clinker and plaster. Clinker is a product made by steady burning of a homogenous special mixture of limestone and clay with predominance of calcium silicate till its baking.

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'.

Vertical roller mills (VRMs) are the main alternative means of grinding the clinker and are increasingly being used. For a quick introduction to VRMs see, for example, this advertisement on Youtube for an FL VRM. As part of the grinding process, calcium sulfate is added as a set regulator, usually in the form of gypsum (CaSO 4.2H 2 O).
The diameter of the grinding chamber D = 200 mm was the same as its length L. The mill chamber was constructed of porcelain and the grinding body stock consisted of 133 corundum balls of 25.1 mm diameter and 11,500 steel beads of 4.9 mm diameter.The grinding stock formulation arose as a result of many years development of ultra-fine cement clinker milling processes.
Cement. Cement production at Unye Cement Plant is in conformity with the standard TS EN 197-1. Portland cement is a hydraulic binder obtained by grinding portland cement clinker after adding a little amount of limestone as a setting regulating agent. It has a high strength gain and high strength as it contains a high amount of clinker.
Gypsum powder or AKA Plaster of Paris is a type of plaster that can be used in architecture, art, fireproofing, and medical applications. When someone talks of "plaster," they are often thinking specifically of plaster of Paris, although there are a number of different types of plaster on the market including lime plaster and cement plaster.
The Correo del Sur newspaper has reported that the company previously delivered 1000t of clinker to Chile-based Cbb's grinding operations in the country. The producer says that it is in the process of securing a supply contract for 80,000t/yr of clinker with its Chilean customer.

Raw materials (clinker, gypsum and anhydrite) sieved (1.18 mm) individually by crusher. After this, in the lab mill, the cement samples is the mixture of various ratio of clinker, and gypsum and anhydrite and have 3650±50 cm2/g fineness. During the grinding process, chemical grinding aid is used. Table 1.
The term grinding aid describes an increase in production at constant product surface area or an increase in surface area at a constant production rate during the grinding of the clinker and gypsum in the finish mill. The practice of this invention may clearly be seen in the following examples. EXAMPLE 1
White cement is a hydraulic binder produced for decorative purposes by grinding white clinker, which is obtained from a mixture of special-quality clay (pyrophyllite, kaolinite) and limestone, with gypsum. It is a type of cement used in binding of elements such as tiles, ceramics in luxurious architectural structures.
