- 2. THE CEMENT MANUFACTURING PROCESS quarry crushing conveyor 3. CRUSHING & TRANSPORTATION 1. BLASTING : The raw materials that are used to manufacture cement (mainly limestone and clay) are blasted from the quarry. Quarry face 1. BLASTING 2. TRANSPORT 2. TRANSPORT : The raw materials are loaded into a dumper. 3. CRUSHING AND TRANSPORTATION : The raw materials, after crushing, are transported to the plant by conveyor. The plant stores the materials before they are homogenized. Next dumper storage at the plant loader
- 3. THE CEMENT MANUFACTURING PROCESS Raw grinding and burning conveyor 1. RAW GRINDING 2. BURNING 1. RAW GRINDING : The raw materials are very finely ground in order to produce the raw mix. 2. BURNING : The raw mix is preheated before it goes into the kiln, which is heated by a flame that can be as hot as 2000 °C. The raw mix burns at 1500 °C producing clinker which, when it leaves the kiln, is rapidly cooled with air fans. So, the raw mix is burnt to produce clinker : the basic material needed to make cement. Next Raw mix kiln cooling Back preheating clinker storage at the plant Raw mill

STORAGE, PACKING, DISPATCH 1.GRINDING : The clinker and the gypsum are very finely ground giving a “pure cement”. Other secondary additives and cementitious materials can also be added to make a blended cement. 2. STORAGE, PACKING, DISPATCH :The cement is stored in silos before being dispatched either in bulk or in bags to its final destination. Back clinker storage Gypsum and the secondary additives are added to the clinker. silos Home page dispatch bags Finish grinding
