Producers also tend to ship their clinker to grinding plants in zones where cement-making raw materials are not available. Arij Global Trading LLC, one of the independent traders of different types of clinker, gray and white in the area, supplies tons and tons of clinker annually.
The grinding costs of clinker are smaller than this cost difference. Furthermore, if clinker is imported then several types of cement can be produced from that clinker, allowing greater flexibility to meet the specific and possibly changing local market demands.
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 sketch.
Jul 12, 2016· Effect of Grinding Aids on Wet Grinding. A variety of additives have been shown to have grinding aid characteristics for grinding cement clinker. Typical among these are amines, organosilicones, glycols, resins, cod oil, kojic acid, carbon blacks, wool grease, calcium sulfate, urea, asphaltenes, etc. Figure 4-26 shows a typical comparison ...

Feb 21, 2019· 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.
Nov 01, 1998· The rate of grinding of the harder component (clinker) is practically the same when ground alone or in mixture; that is, the breakage rate function values for clinker are mixture-composition independent, at least within the grinding time period examined, when clinker is …
• The surface energy of the clinker covered with grinding aid(E) is the algebraic summation of E1,E2 and E3. E= E3 + E2 + E3 11-05-2015 Indian Institute of Technology,Delhi 13 14. • If E = -ve that means the energy is released and the grinding aid spreads out on clinker's surface.
Clinker is moved along the beds via reciprocating motion of independent lanes within the bed actuated by hydraulic cylinders. As each lane moves forward 100 % of the clinker in it moves with it, on the back stroke however, only 25% of the clinker is moved.

Jan 10, 2021· Proper grinding is crucial to ensure a good behavior of blended cements. The different grindability of the SCMs and the clinker grains makes intergrinding challenging . In general, SCMs are softer than clinker and thus will tend to overgrind while the clinker grains remain coarse .
Clinker Grinding. Clinker and gypsum, being mixed together in predetermined proportions, are fed to the grinding mills. Chemical gypsum, if used instead of natural gypsum, needs to be dried either by natural sun drying or by mechanical drying, before it is used with cooled and dried clinker for inter - grinding in mills.
