Kaibang charcoal machine manufacturer summarizes the precautions when drying raw materials

Charcoal machine is a professional equipment for producing machine-made charcoal. The production process must go through the steps of crushing-drying-rod making-carbonization, among which the drying of raw materials is a very important step. Kaibang charcoal machine manufacturer summarizes the precautions when drying raw materials.

1. The form of the material is as large as formed wood, ceramic products, and flake, fiber, granular, fine powder, paste and liquid materials, all of which need to be dried in industry. Therefore, the selection of dryers should first be based on the form of the material;

2. The state of the combination of the material and water determines the difficulty of drying, the energy consumption level and the length of the required residence time in the dryer, which has a lot to do with the selection. For difficult-to-dry materials, it is mainly to give a longer residence time, rather than to strengthen the external conditions of drying;

3. Various physical properties of the material; including density, bulk density, particle size distribution, heat capacity and adhesion properties of the material. The level of adhesion has a great influence on the feeding and discharging of materials and the work of certain forms of dryers. When the adhesion is serious, the drying process cannot be carried out.

4. The characteristics of the material during the drying process. Including heat sensitivity, some materials will change color and decompose and deteriorate after being heated. The shrinkage of the material during the drying process will cause the molded product to crack or deform, thus reducing the quality of the product or even making it scrapped.
