Thermal energy consumption and its conservation for a cement production ...

The consumption of the energy in the cement plant is mainly due to raw mill, cooler, preheater and rotary kiln . The total energy loss of the plant is generally accounted for about 3539% of the total energy input . This energy loss is due to the loss from the exhaust gas, cooler and the radiation heat transfer from the kiln cell.

Cement Manufacturing Process | Phases | Flow Chart | Cement

Raw materials are extracted from the quarry and by means of conveyor belt material is transported to the cement plant. There are also various other raw materials used for cement manufacturing. For example shale, fly ash, mill scale and bauxite. These raw materials are directly brought from other sources because of small requirements.

Cement manufacturing components of a cement plant Understanding Cement

Summary of production process. Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the 'raw feed' or 'kiln feed' and is heated in a rotary kiln where it reaches a temperature of ...
