JDSH new three-cylinder dryer

JDSH new three-cylinder dryer_Yancheng jishengda Environmental Protection Engineering Co., Ltd.

The sleeve type three-cylinder dryer is mainly used for drying granular materials in a certain humidity and particle size range, such as yellow sand used in the dry-mix mortar industry, various molding sands used in the foundry industry, blast furnace slag used in the building materials cement industry, and small-sized clay. The chemical industry can not afford chemical changes, and is not afraid of high-temperature and dusty small particles. According to the requirements of different industries for the final moisture content of the dried materials, the moisture content of the dried materials can reach 1-0.5% or less. The material entering the dryer is preferably a non-stick wall and a lifting plate. The temperature of the gas entering the heat exchange in the dryer should not be higher than 750 °C. If there is special high temperature drying requirements, the inner cylinder and the lifting plate at the entrance of the dryer can be made of heat-resistant steel.


The telescopic three-cylinder dryer has a compact structure and a small footprint. It is one-half of the area of ​​the same-volume single-cylinder dryer, with reliable operation, low energy consumption and high thermal effect. Material drying effect is good, easy to achieve automatic control, less operators, etc.

Auxiliary equipment for telescopic three-cylinder dryer: Electromagnetic vibrating feeder or disc feeder, bucket elevator, hot blast stove, transmission system, vibrating screen, conveying equipment, etc. The burners of the co-heating furnaces have various forms such as fuel, combustion gas, coke burning, and coal burning. Among them, coal burning is the most common, and users must indicate when ordering.
