It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker, grinding the clinker, and adding 2-3% percent of GYPSUM. Several types of Portland cement are available. The most common, called ordinary Portland cement (OPC), is grey, but white Portland cement is also available. The manufacturing process for Hoffmann Green cements is based on the systematic use of abundant co-products as a substitute for natural resources. This innovation makes it possible to produce a carbon-free cement 0% clinker while preserving natural resources, particularly without the use of quarries.

Process description Clinker manufacturing unit is located at Village-Risda, Suhela Road, Baloda Bazar, Chhattisgarh. It consists of preheater with cyclone, raw mill, crusher, calciner and kiln, cooler etc. Its capacity is 3200000 metric ton per year of clinker production. Raw material is Clinker is the intermediate product used in the manufacturing of cement. There are two primary processes used to manufacture clinker the dry process and the wet process. Our plants use the dry process, which is more energy efficient. In the wet process, the raw materials are mixed with water to form slurry, which is fed into a kiln.

The clinker manufacturing process The preheating of the material takes place in pre-heater cyclones fitted with a pre-calciner fired with petroleum, natural gas or coal. The calcinations of the material begin during this stage, changing its phase to the oxide phase for each component to Cement manufacturing has several opportunities for WHR, specifically in the process step where the clinker material is produced. For clinker production, a mixture of clay, limestone, and sand is heated to temperatures near 1500C. The kiln and clinker cooler have hot exhaust streams where waste heat could be recovered.

Under the process, the raw material can be fully mixed with the hot gas discharged from the kiln, increase the contact area of the gas material, fast heat transfer speed, and high heat exchange efficiency, thereby improving the production efficiency of the rotary kiln system and reducing the heat consumption of the clinker. Clinker is cooled and ground with approximately 5 percent gypsum and other minor additives to produce Portland cement. The heart of clinker production is the rotary kiln where the pyroprocessing stage occurs. The rotary kiln is approximately 20 to 25 feet (ft) in diameter and from 150 ft to well over 300 ft

Initially it moves the clinker to the entrances of the coolers, and then into the coolers themselves. The most common type of coolers are the satellite and grate collers. To speed up the process, cooling air is blown in against the clinker flow, and the resulting hot air is used for burning the fuel. The homogenization is very important to the white cement manufacturing process, its multi-component mixtures are generally more prone to segregation than raw materials used in the gray cement production lines.

Cement production also is a key source of CO2 emissions, due in part to the significant reliance on coal and petroleum coke to fuel the kilns for clinker production. Globally, CO2 emissions from cement production were estimated at 829 MMTCO2 in 2000 7, approximately 3.4% of global CO 2 emissions from fossil fuel combustion and cement production. Aug 20, 2015 In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. The result is called clinker, which are rounded nodules between 1mm and 25mm across. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement.
