Points to pay attention to when drying materials with sand dryer

  When using the sand dryer, the user must carefully read the operating regulations and understand the working principle of the sand dryer in detail, so that it can be handy during the actual operation, otherwise, the sand dryer may not meet the expected drying requirements when drying materials. The following are four considerations for the sand dryer when drying materials.

  1. The combined state of materials and moisture is a factor that determines the difficulty of drying, and also determines the length of time the materials stay in the sand dryer. These conditions are inseparable from the selection of drying equipment. For example, for some materials that are not easy to dry, a longer residence time should be given instead of strengthening the external drying conditions.

  2. The shape of the material. Materials can exist in many forms, such as large shaped wood, ceramic products, or other flake, fiber, granular or even liquid materials. These can be used as materials that need to be dried in industry. Therefore, the selection of sand dryer equipment should also be considered according to the form of the material.

  3. Look at some physical properties of the material itself. The physical properties of the material itself generally consist of density, bulk density, heat capacity, and material adhesion, etc. Especially the level of adhesion, it has a direct impact on the work of the drying equipment, when the adhesion is very serious, the drying process cannot be carried out.

  4. Some matters needing attention in the drying process of materials. These factors mainly include heat sensitivity when heated, and some materials will undergo some changes when heated, such as discoloration, decomposition and deterioration. In addition, due to the shrinkage of the material during the drying process, the material will deform or crack, which will result in the quality of the material being reduced or even scrapped.
