Three Cylinder Dryer
Outer tube diameter （m) : 2.1-3.5
Slag initial water（％） : 15-18
Introduction
Three-cylinder dryer equipment can dry dry mortar, yellow sand, cement slag, clay, coal gangue, mixed materials, fly ash, gypsum, iron powder and other raw materials, widely used in building materials, chemicals, castings, etc. industry.
working principle
The material is fed into the inner layer of the rotary drum of the three-cylinder dryer by the feeding device to achieve the downstream drying. The material is continuously picked up and scattered under the copying board in the inner layer and spirally conveyed to achieve heat exchange. The material is moved to the inner layer. The other end enters the middle layer and is counter currently dried. The materials are continuously raised in the middle layer, and it is a two-step step backwards. The material in the middle layer not only fully absorbs the heat dissipated by the inner drum, but also absorbs the heat from the middle drum. At the same time, the drying time is prolonged and the material reaches the optimum dry state here.

Advantage
three cylinder dryer equipment investment is 1/6 of imported products, using alloy steel plate, wear 3-4 times than ordinary steel plate.
The initial moisture content of the material is 15%, and the final moisture content is ensured to be 0.5-1% or less. It is the first choice for cement plants, slag powder and dry mix mortar production lines.
Three-cylinder dryer thermal efficiency up to 80%, increase thermal efficiency 48%.
Fuel can be adapted to white coal, bituminous coal, coal gangue, oil, steam, can bake 20-40mm below the block, pellets, powdered materials.
The three-cylinder dryer reduces the floor area by about 50% compared to the single-cylinder dryer, and reduces the civil engineering investment by about 50%.
according to user requirements can easily regulate the desired final moisture index.
The cylinder temperature of the three-cylinder dryer is only 60 degrees, the exhaust gas temperature is less than 100 degrees, and the time for the baghouse of the dust-removal equipment is more than 2 times longer. It is all water vapour.
The three-barrel dryer coal consumption is 1/3 of the single-tube dryer, saving 40%. Small-sized dryers have annual coal consumption of 500,000 to 100 million yuan, and large model dryers have annual coal savings of 100 to 2 million yuan.
