THIS IS A SCHEMATIC PRESENTATION OF THE WHOLE MANUFACTURING PROCESS
- Raw materials such as limestone, shale and marl are collected at the quarry and transported to the crusher where they are crushed.
- From here it is conveyed to the mixing bed where it is mixed to a homogeneous material by means of stack and rake.
- Additives such as high grade limestone, sand and iron ore are added and then conveyed to the raw mill where it is dried and ground to a fine powder.
- The raw meal is transferred to the pre-heater were the material is pre-heated. RDF, coal and woodchips are used to heat the preheater after which it enters the rotary kiln where it is burned to produce clinker.
- The clinker is cooled down with air in a grate cooler and then stored in the clinker silo.
- Additives such as gypsum and limestone are added to the clinker before being milled in the cement mills to the final cement product.
- The cement powder is stored in the cement silos. From here the final stage is the bagging or bulk dispatch of the cement.
