Cement production and cooling

 · Gypsum is then added to the composition and the cement clinker is ground down into cement powder, ready for storage, packaging and transport. HOW IS CEMENT COOLED? Cement cooling is an important step in the cement production process, as it reduces the chance of gypsum dehydration and the formation of lumps, reducing the overall quality of the final cement.Usually gypsum is used in low quantity (about 5%) in order to control the setting time of cement and control C3A. Adding more gypsum will affect the quality of cement and tits setting time. Get Price

Role of Gypsum in Cement and its Effects

 · Gypsum is a mineral and is hydrated calcium sulphate in chemical form. Gypsum plays a very important role in controlling the rate of hardening of the cement, so its is generally termed as retarding agent of cement. It is mainly used for regulating the setting time of cement and is an indispensable component.Gypsum plays a crucial role in cement. Though it is used in a small quantity, in the range of 2. 3.0 percent in terms of SO3, gypsum's role in cement is significant, more predominantly at early ages.

use of sodium sulphate in cement production

 · Re: use of sodium sulphate in cement production Sodium sulphate can be added in PPC cement production. The aim would be to increase the early hydraulic reactivity of the cement. In PPC cement that would act as a form of alkali activation of the pozzolanicmanufacturing cement uses 2 to 4 per cent gypsum per tonne of cement. Thus the country requires importing substantial gypsum to cater to the requirements of cement industry. This has made the cement industry to look at the usage of different varieties of
