Three cylinder rotary dryer

Product Details

The three cylinder drum dryer (three-pass) adopts a embedded structure, which is formed by embedding three concentric cylinders (inner cylinder, middle cylinder, and outer cylinder) of different diameters to form a circular cylinder with circular heat preservation, which improves the drying efficiency. Reduced gas (fuel) consumption. The cylinder is equipped with lifting plates and guide plates of different angles and spacings. These lifting plates and guide plates can ensure that the material to be dried moves in the direction of the cylinder's movement under the action of gravity, and keep the material in the cylinder with a sufficient residence time and adequate clearance. The length of the cylinder is only one third of the single cylinder dryer, thereby greatly reducing the floor space and the building construction area.

The three cylinder drum dryer is mainly used for drying yellow sand, molding sand, slag, small-grained clay, and other small particles that are not afraid of high temperature and dust pollution. The moisture content of the dried material can reach 1-0.5% or less, and it is widely used in the drying of various loose materials in metallurgy, chemical and other departments. The machine has the characteristics of compact structure, high thermal efficiency, low energy consumption and reliable operation.

Working principle:

The material to be dried enters the dryer through the belt conveyor, and the riding wheel & the roller drive the cylinder to rotate. Under the action of the lifting plate and the guide plate on the inner wall of the cylinder, the material is continuously picked up and scattered to spiral. The heat exchange is realized. The material enters the middle cylinder with the direction of the guide plate for countercurrent drying. After fully absorbing the heat emitted from the inner cylinder and the middle cylinder, the material enters the outer cylinder. The material enters the discharge bin and is sent to the designated position by the belt conveyor.

Main features:

1. The final moisture content of the material is guaranteed to be less than 0.5%, and it is the first choice for dry-mixed mortar and slag powder production lines.

2. The thermal efficiency of the cylinder self-insulation is as high as 70% or more (the thermal efficiency of the traditional single-cylinder dryer is only 35%), which improves the thermal efficiency by 35%.

3. The fuel could be coal, oil and gas. It could be used to dry bake blocks, granules and powdery materials below 20mm.

4. Compared with the single cylinder dryer, it occupies about 50% less land, reduces civil investment by about 50%, and reduces power consumption by 60%.

5. The final moisture can be easily adjusted according to user requirements.

6. The outlet air temperature is low, and the dust removal equipment has a long service time.

Note:

1. These parameters are calculated based on the initial sand moisture content: 10-15%, and the humidity after drying is less than 1%. .

2. The temperature at the inlet of the dryer is 650-750 degrees.

3. The length and diameter of the dryer can be changed according to customer requirements.
