How to Make Cement Clinker

Cement clinkers are formed by the heat processing of cement elements in a kiln. Limestone, clay, bauxite, and iron ore sand in specific proportions are heated in a rotating kiln at 2,770 Fahrenheit (1,400 Celsius) until they begin to form cinder lumps, which are also known as cement clinkers. Cement clinkers are usually ground with gypsum to produce the fine powder later mixed with liquid to produce cement, although some manufacturers ship cement clinkers in their lump form to cut down on dust.

Cement Clinker Application

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates. Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually define the capacity of the cement plant. As the main energy-consuming and greenhouse-gas-emitting stage of cement manufacture, improvement of kiln efficiency has been the central concern of cement manufacturing technology.

How to Make Cement Clinker

Cement clinker is widely used, how to make cement clinker which is very concerned about the problem. Manufacture of cement clinkers has environmental ramifications, beginning with the dust, noise, and vibration caused by mining for natural raw materials.

Cement kilns also eat through a substantial amount of fuel, and polluting equipment is used at most stages of cement manufacture. However, some of these effects are offset by the reuse of slag, fly ash, and silicate byproducts. Furthermore, many cement manufacturers use other agricultural and industrial byproducts to fuel the kilns, helping to dispose of these materials.

Cement, when mixed with water, forms a very strong alkaline solution. Gloves and eye protection should be worn at all times when working with cement, and cement should be washed from the skin immediately to prevent skin injury. Once cement hardens, it can be handled without precautions.
