The main component of limestone is calcium carbonate, which is a common non-metallic mineral and widely used. The limestone that has just been extracted from the vegetable market needs to go through a series of technological processes before it can be used for production, among which drying is the most important process. Limestone drying requires the use of a limestone drum dryer. Next, I will introduce the necessity of limestone dryers in limestone processing based on different applications of limestone.

  1. Building materials industry

  After limestone is crushed to a certain fineness, it can be used as a soil amendment and calcium fertilizer to be spread into the soil, improving soil fertility. The moisture content has a great impact on the effectiveness of fertilization. If the moisture content is high, lime powder will clump and cannot be evenly scattered, and it is easy to agglomeration and deterioration. After drying, it can ensure good fluidity and stability.

  2. Fertilizer industry

  After limestone is crushed to a certain fineness, it can be used as a soil amendment and calcium fertilizer to be spread into the soil, improving soil fertility. The moisture content has a significant impact on the effectiveness of fertilization. If the moisture content is high, lime powder will clump and cannot be evenly scattered, and it is prone to agglomeration and deterioration. After drying, it can ensure good fluidity and stability.

  3. Chemical industry

  Limestone can also be used to produce high value-added chemical products such as soda ash and light calcium carbonate. For example, when generating light calcium carbonate, the first step is to calcine limestone. If limestone contains moisture, it will directly affect the quality of the final product. At the beginning, using a limestone dryer to remove the moisture is beneficial for obtaining a purer product. 

  The processing of limestone requires various stages such as crushing, grinding, calcination, and granulation. Using a limestone dryer to dry limestone is a key step in ensuring the quality of the finished product. It avoids the agglomeration of lime powder, improves calcination efficiency, reduces energy costs, and can produce higher quality products.
