In the cement industry, when dry production is used, various water-containing substances such as raw materials, coal, and mixed materials need to be dried. When wet-processed, coal and mixed materials also need to be dried to ensure powder. The grinding operation is carried out normally. These all require a dryer to complete.
The moisture of the milled material has a great influence on the mill's output, the quality of the milled material and the operation of the mill. The material to be milled has a lot of water, and the moisture content in the mill is high. The fine particles will adhere to the grinding body, the lining plate and the partition plate, so that the grinding efficiency is lowered. Moreover, the excessive moisture of the material to be milled will inevitably cause the mill to be grinded. Deteriorating operating conditions make operation and quality control difficult. In addition, the mixing ratio of the material fed into the mill will be affected by the fluctuation of the moisture in the material, so that the quality of the milled product is also affected. Therefore, the drying process using a dryer to remove excess moisture from the material is an indispensable part of cement production.
