Three-cylinder dryer equipment can be used for dry processing of mortar, yellow sand, mixed materials, fly ash, gypsum, iron powder, cement slag, clay, coal gangue, and other raw materials, which is widely used in building materials, chemicals, castings industry, etc.
Working Principle
The mineral material is fed into the inner layer of the rotary drum of the three-cylinder dryer by the feeding device to achieve downstream drying and 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 while the other end enters the middle layer and is counter currently dried. Then the materials are continuously raised in the middle layer and 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.
Advantages
1. The equipment investment of about three-cylinder dryer is 1/6 of imported products.
2. It adopts an alloy steel plate, which makes the wear 3-4 times that of an ordinary steel plate.
3. The final moisture content is ensured to be 0.5-1% or less, so the three-cylinder dryer equipment is the first choice for cement plants, slag powder, and dry mix mortar production lines.
4. It can easily regulate the desired final moisture index according to user requirements.
5. The thermal efficiency of a three-cylinder dryer up to 80%, which increases thermal efficiency by 48%.
