Rotary dryer was delivered to customer today.

The Rotary dryer customized by Chinese customers was delivered to the customer today after completion of production.This rotary dryer customized by the customer has a diameter of 1 meter and a length of 10 meters, with a drying capacity of 1-3.5 tons per hour.

The rotary dryer, also known as a rotary drum dryer. It is widely used in the building materials, metallurgy, chemical industry, and cement industry for drying limestone, coal powder, slag, clay, etc. The machine is mainly composed of components such as the rotating body, material lifting plate, transmission device, support device, and sealing ring. It has the advantages of a reasonable structure, high quality construction, high output, low energy consumption, and convenient operation.

Structure of rotary dryer:

In order to increase the material evenly distributed in the rotor parts of the cross section in good contact with the drying medium, in the cylinder body installation raise plates. There are several types of raise plate.
1). lifting type: For large or easy to bond the material in the tube wall.
2).Four formats type: Suitable for big density, not crisp or not easily scattered materials. The raise plate will be divided into four panes, and were mutually connected fan-shaped workout room, Materials and the contact surface of the hot gas than large of the lifting type, and also can increase of the filling material rate and reduce material landing height and reduce dust quantity loss and so on.
3).Cross-shaped or frame-shaped: applicable to brittle and easy dispersion small pieces of material, make the material can be evenly dispersed in cylinder whole section.
4).Sleeve type: For double entry Heat transfer for the double (or half the diameter heating) rotary drum dryer raise plate.
5).Separate format (fan): For very fine particles and the material prone to flying powder. materials accumulate on grid board when it into, then cylinder rotates, the material is turning and continue contacts with the hot gases, at the same time, the decrease of height landing, reducing the dry material being gas away possibility.

Working Principle:

1 Materials are sent to hopper of dryer by belt conveyor or bucket elevator  

2 Materials enter the barrel installed with slope to horizontal line from the higher side  

3 Hot air enters the barrel from the lower side, and then materials and hot air mix together  

4 Materials go to the lower side by gravity when the barrel is rotating  

5 Lifters on the inner side of barrel lift materials up and down in order to make materials and hot air mix completely, which is designed to improve the producing efficiency of dryer drying machine.
