Drying material characteristics of three drum sludge drying equipment selection

When selecting three drum sludge drying equipment, users need to pay attention to a lot of matters. For example, the characteristics of materials are different, so the drying methods used are also very different, so the type of equipment selected is also very different.

1、 The combination of material and moisture has a great influence on the drying difficulty, and can also determine the energy consumption of equipment and the residence time of materials in the cylinder, which has a great relationship with the selection of three drum sludge drying equipment. For some materials that are not easy to dry, it is necessary to extend the residence time in the cylinder rather than strengthen the external conditions.

2、 The form of the material. Due to the various forms of materials, such as granular, block, fiber, sheet, etc., these shapes will also affect the selection of equipment. The drying internal structure of different material forms also has great changes. General manufacturers are based on the user's material form to determine the internal drying structure.

3、 Physical properties of materials, such as density, adhesiveness, bulk density, etc. In particular, the adhesion of materials has an impact on the drying efficiency of three drum sludge drying equipment. Due to the high adhesion of materials, it is easy to agglomerate and stick to the cylinder wall during the drying process. If it is light, it will affect the drying efficiency of the equipment, and seriously block the equipment, resulting in the equipment unable to operate normally.

4、 In addition, some materials are easy to be affected by high temperature in the drying process, but some thermal reactions are produced by the materials, which makes the materials undergo some chemical reactions, such as discoloration, decomposition and deterioration, and even deformation or cracking due to material shrinkage during drying, which leads to the decrease of material quality after drying, and affects the value of material recycling.
