How To Apply Cement Vibrating Screen In Cement Production?

It is made of limestone and clay as the main raw materials, crushed, batched and ground into raw materials, then fed into the cement kiln to calcine the mature materials, and then finely ground the clinker with appropriate gypsum (sometimes mixed with mixed materials or additives).

The method of drying and grinding raw materials at the same time, or first drying and grinding raw meal powder, and then feeding into the dry kiln to calcine into clinker. However, there are also ways to add some water into the raw meal powder to make raw meal balls, which are sent into the Labor kiln to be calcined into clinker, which is called the semi dry process. It is still one of the dry production methods. 1.2 Wet production; The method of feeding raw materials into wet kiln to calcine mature materials after grinding them into raw slurry with water powder.

The main advantage of dry process production is low heat consumption (for example, the heat consumption of clinker of dry process kiln with preheat is only 3140~3768 J/kg), while the disadvantage is that the composition of raw meal is not easy to be uniform, the workshop is dusty, and the power consumption is high.

Wet vibrating screen kiln can be divided into wet long kiln and wet short kiln with slurry evaporator. Long kiln is widely used, but short kiln is rarely used at present. In order to reduce the heat consumption of wet long kiln, various types of heat ex changers are installed in the kiln, such as chain, slurry filter preheat , metal or ceramic heat ex changer.

The fine grinding of cement clinker usually adopts circular flow grinding process (i.e. closed circuit operating system). Electric dust collectors, bag type dust collectors and cyclone dust collectors are commonly used in cement plants.

In recent years, due to the adoption of new technologies and equipment in raw material pre homogenization, homogenization transportation of raw meal powder and dust collection, especially the appearance of decomposition technology outside the kiln, a new dry production process has emerged. With this new process, the clinker quality produced by dry process is no less than that produced by wet process, and the power consumption is also reduced, which has become the trend of cement industry development in various countries.

Cement vibrating screen: as the front supporting equipment of various cement packaging machines, cement shale shaker is also an indispensable equipment in the cement production process. As the cement industry has high requirements on the particle size of finished products, the final inspection process must be carried out before product packaging. The cement vibrating screen is used to screen out lumps and foreign matters in cement and other powdery materials to ensure the quality of products.
