In this process will need some cement crusher machines, such as jaw crusher, impact crusher,VSI crusher and so mixture is then heated and burnt in a preheater and kiln to be cooled in an aircooling system to form clinker, which is the semifinished form. This clinker is cooled by air and subsequently ground with gypsum to form cement.
On average – tonnes of coal are consumed in the kiln per kilogram of clinker cement production. As such coal storage during cement manufacturing is an important component to consider in hazard analysis. Among the various causes of coal fires, spontaneous combustion during storage results in a large number of losses.
Apr 13, 2020 · The manufacture of Portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, these materials partially fuse to form nodular shaped clinker by broking of chemical .
