Dry and wet process cement clinker grinding plant
1. Production process of cement
A cement clinker grinding plant consists of the following three processes.
(1). Raw material process
(2). Clinker burning process
(3). Finish grinding process
The raw material process and the clinker burning process are each classified into the wet process and the dry process.The raw material process and the clinker burning process are each classified into the wet process.In the dry process, crushed raw materials are dried in a cylindrical rotary drier having a diameter of 2 m and a length of about 20 m for example, mixed by an automatic weigher, ground and placedin storage tanks. The resultant mixture is further mixed to make the ingredients uniform, and sentto a rotary kiln for clinker burning.

2.Raw material process
Since raw materials can be homogenized and the mixing ratio can be corrected after grinding, this process is relatively simple.

PIC3 shows three processes a, b and c. Raw materials received by a plant contain a small amount of water. Limestone contains 2 to 5% of water and clay about 5 to 10%. The dry process needs to evaporate water when grinding. In PIC3, process a is provided with an independent dryer to evaporate water, and the dryer may be a rapid dryer or impact dryer with a disintegrating or crushing function instead of the rotary dryer as illustrated. - 4 - In PIC3, process b is a closed circuit grinding process combining an air separator and a ball mill or tube mill, which is provided with drying function. The above mill and separator are available in several types. In PIC3, process c is an example of vertical roller mill. For drying, exhaust gas from the kiln and preheater is used, but sometimes a hot gas generator is installed for a time of commissioning of the plant and for a time of year when water contained in raw materials increases.
