The main function of the coal dryer is to dry the coal material with high moisture content. After drying, the calorific value of the material is further improved, which has higher economic benefits and reuse value. So what are the drying methods of coal dryers?
High-temperature hot air and low-temperature hot air are two common methods of coal drying at present. Both methods can quickly dry coal materials. The main difference between the two is the difference in heat source.
1. High-temperature hot air is a commonly used method of coal drying. It mainly adopts the direct-heat drying process. The high-humidity coal is fully contacted with high-temperature hot air or hot smoke under the evenly distributed copying plate in the cylinder, so as to achieve rapid coal evaporation. purpose of moisture. The heat source is generally coal-fired or gas-fired heating equipment.
2. Low-temperature drying, that is, low-temperature steam coal drying equipment, adopts a tubular tube bundle drying structure and an indirect drying process. The high-humidity coal is in full contact with the tubular heat exchanger under the evenly distributed copying plate in the cylinder body. To achieve the purpose of heat and mass transfer.
The above are two ways of drying coal. Zhengzhou Jiutian is a professional manufacturer of coal dryers, with many models of equipment, many choices of heat sources, and can be customized. If you are interested in our coal dryer machine, please feel free to contact us.
Recently, the equipment for the continuous carbonization machine project cooperated by Inner Mongolia customers and Zhengzhou Jiutian has been installed and is about to be put into production.
Wood shavings are the most common animal bedding material due to their use in absorbency and odor control. However, the production process of shavings produces dust and grease, which can cause problems for animals. Therefore, the shavings must be dry to e
Recently, the coal slime dryer equipment customized by Zhengzhou Jiutian for customers in Yangquan, Shanxi was hoisted in the Jiutian workshop and will be shipped soon.
The steam rotary dryer is also called a tube dryer. The heat source is waste heat steam from power plants and boiler plants. Through technological transformation, it is converted into the temperature and heat energy required by the material. It has the ad
