What is the difference between Clinker and Cement? • Clinker is a substance produced in the middle stage of the cement manufacturing process. When clinker is ground with gypsum, cement is formed. • Clinker is a marble like nodules, whereas cement is a very fine powder. • Cement is used in building and is a good binder.

Another traditional test of the finished clinker was the "litre weight", in which the bulk density is measured on a carefully sieved size range of the clinker (usually 2.5-5 mm or 5-10 mm, whichever preponderates).

cement plants would increase to 115-130 kWh/t cement in 2030 and to 115-145 kWh/t cement in 2050. PROCESS OVERVIEW – Cement is a solid material made of clinker, gypsum and other additives.
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.

Portland cement clinker - overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties. This page gives a thumbnail …

Cement Manufacturing Process Phase 1: Raw Material Extraction Cement uses raw materials that cover calcium, silicon, iron and aluminum. Such raw materials are limestone, clay and sand.
In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter, produced by sintering (fused together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

The process of grinding cement which includes the step of adding a water dispersion of a lignin compound to the cement clinker in an amount insuflicient to cause the substantial hydration of the resulting cement and thereafter grinding the clinker.
By 1950, a typical large, wet process kiln, fitted with drying-zone heat exchangers, was 3.3 x 120 m in size, made 680 tonnes per day, and used about 0.25–0.30 tonnes of coal fuel for every tonne of clinker produced.
Cooled clinker and 3 to 5 percent of gypsum are ground in ball mill to required fineness and then taken it to storage silos from where the cement is bagged. The equipments used in the dry process kiln are comparatively smaller.

In the manufacture of Portland cement, clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter, produced by sintering (fused together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
A dry process kiln might be only 70m long and 6m wide but produce a similar quantity of clinker (usually measured in tonnes per day) as a wet process kiln of the same diameter but 200m in length. For the same output, a dry process kiln without a precalciner would be shorter than a wet process kiln but longer than a dry process kiln with a precalciner.

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
