How to Control material moisture and temperature when Drying
- Nov 12, 2018 -

100% drying of materials with a dryer is the ultimate goal that users want to achieve when choosing a dryer. However, in actual production, some material with high viscosity, high humidity and unsatisfactory drying effect.

Zhongbo Heavy as a rotary dryer manufacturer think that the material moisture before drying is generally high. If drying immediately it will increase the drying costs of the enterprises, according to our experience we recommend using natural drying to reduce the moisture content by about 20% and then using rotary dryer for drying. When material turnover in drying drum, the moisture inside the body needs to be transferred to the surface of the bulk material before it can be evaporated. If the material block is too large, the surface hardness will be higher or dry will not be conducive to evaporation of water, so the smaller the material block is, the better, which can reduce the process of water transfer, and the surface of the material is not hard to harden or keep a certain humidity is the best. According to the working principle of the rotary dryer,the material can be dried by evaporation of moisture at high temperature.

When the dried material is a whole large piece and be fed into the drum dryer for drying, the material also evaporates moisture, but according to the properties of the material, when the temperature reaches a certain value, the material will become hard. As we all know from our daily life, if the soil is slabs, the soil absorbs water slowly, if the soil is loose or has a certain humidity. The water will soon be absorbed by the soil. In principle, the smaller the particle size of the material, the better, but the powdered material can be loaded inside the dryer drum because it is easy to agglomerate into a hard plate and is not easy to dry when drying. A device for clustering materials.
