Product Brief Introduction
The three cylinder dryer improves the internal structure on the basis of single drum dryer, the pre drying of wet material is added before getting into the dryer and prolong the drying time of wet material in the dryer. It is widely used in various industries’ slag, clay, coal, iron ore powder, ore powder, and dry mixed mortar, yellow sand and other mixed materials.
Product advantages
Working Principle
Materials get into the internal rotary drum from the feeding device, to realize the downstream drying, materials are lifted up and down constantly by the inner layer lifting plates and the heat exchange is realized under the form of spiral moving, materials move to the other side of the inner cylinder and then get into the middle cylinder, and materials are lifted up and moved forward in the middle cylinder, by the way of two steps forward and one step back, materials absorb the heat both coming from the inner cylinder and the middle cylinder, meanwhile, the drying time is prolonged, and materials reach optimum drying status at this stage. Material move the other end of the middle cylinder and then get into the outer cylinder, the dried materials are quickly discharged from the cylinder under the function of hot wind.
Product Parameter
Product Application
Sand dryer (river sand dryer) is mainly used to dry granular materials within a certain humidity range, such as yellow sand used in the dry powder mortar industry, and various specifications of molding sand in the foundry industry. Blast furnace slag used in building materials and cement industry. Small particle size clay, the chemical industry is used for small particle materials that can not bear chemical changes, are not afraid of high temperature and dust pollution. According to the final moisture requirements of materials after drying in different industries, the moisture content of materials after drying can reach below 10.5%.
It is advisable that the material entering the dryer should not stick to the cylinder wall and the lifting plate. The temperature of the gas entering the dryer for heat exchange should not be higher than 750 degrees Celsius. If there are special requirements for high-temperature drying, the inner cylinder and the lifting plate at the entrance of the dryer can be made of heat-resistant plates.
