Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

China Small Cement Clinker Grinding Mill Complete Plant, Find details about China Cement Clinker Grinding Plant, Cement Clinker Grinding Mill from Small Cement Clinker Grinding Mill Complete Plant - Xinxiang Great Wall Steel Casting Co., Ltd.
Scope Description. The products covered by this order are gray Portland cement and clinker from Japan. Gray Portland cement is a hydraulic cement and the preliminary component of concrete. Clinker, an intermediate material produced when manufacturing cement, has no use other than grinding into finished cement.
Portland cement clinker is a hydraulic material which shall consist of at least two-thirds by mass of calcium silicates (3CaO.SiO 2 and 2CaO.SiO 2), the remainder consisting of aluminium and iron containing clinker phases and other compounds.The ratio of CaO to SiO 2 shall not be less than 2.0. The magnesium oxide content (MgO) shall not exceed 5.0% by mass.
EP 2336100 A1 describes additives for mineral binders with reduced browning potential, comprising a grinding aid selected from glycols, monocarboxylic acids having 1 to 4 C atoms and polycarboxylate ether comb polymers, as well as a retarder, which can be used in the cement clinker grinding process. DESCRIPTION OF THE INVENTION
Clinker Grinding is the final step in cement production. The cooled clinker is a kind of granular material with different particle size. They will be ground in the grinding mill to reach the qualified fineness of cement product. During the grinding, 2-3% gypsum powder is added as retarder so that when cement contacts with water, its ...
brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
A cement clinker grinding aid which comprises a styrene-maleic anhydride copolymer (SMA) superplasticiser. The SMA is preferably a type with polyoxyalkylene-based side chains. Use of the grinding aid renders the grinding process more efficient and improves the performance of cementitous compositions in which the cement thus ground is used.
Phase V: Clinker Cooling & Final Grinding. The hot clinker discharged from the rotary kiln is cooled in the grate cooler by forced air, which is extracted from the outer atmosphere by grate cooling fans. The temperature of the clinker after being cooled drops from 1350 – 1450⁰C to around 120⁰C.
Clinker grindability is determined by quantity of electricity consumed for grinding (kW / ton) under other equal conditions. In cement production entire crushing and grinding process consumes about 85% of the electricity. At the same time 75% of electricity consumed for milling and only 2-20% of them consumed for grinding.
