Rotary dryer is widely used in building materials, metallurgy, chemical industry and cement industry, which is widely used to dry the stuff such as limestone, coal powder, slag and clay.Drum drier is a drying device, widely used in mining equipment. It can be divided into two categories, direct and indirect heat transfer drum dryers.
1 Efficient drying ability
2 Adopt new YIGONG drying technelogy
3 Long service life, stable operation
The introduction of rotary drier:
The main internal structure of rotary drier:
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 pane, 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.
Above all forms of plate can be distributed throughout the cylinder body. In order to make the material quickly and evenly to the lift board, can also install spiral guide stripper plate 1~5 metres at feed-throat, To avoid the wet bonding material accumulation in the tube wall. At the same time due to drying of material can easily be raised and taken away by waste gas, while in discharging end 1 ~ 2m place not install any Yang board. Raise plate
Rotary dryer's operating principle:
Dry and wet material from the belt conveyor or bucket elevator to the hopper,
Then by feeding machine of hopper through charging pipe into the feed side. Feeding pipeline's slope than the natural material, in order to materials smoothly into dry containers. Drier with the horizontal cylinder is a slightly into tilted rotating cylinder. Material from high end to join, heat body by low-end enter, with material into counter-current contact, also have heat body and materials together and flow into the barrel. With the cylinder rotate by gravity materials to a run on the bottom of the end. Wet materials in the cylinder body forward movement process, directly or indirectly got heat body heat, make wet materials to dry, then the discharge end by the belt conveyor or screw conveyor sent. In the cylinder body wall with copy plate, It is the function of the material copied up and planted, make the material and the airflow contact surface increases to improve the drying rate and to promote material progress. Heat-carrier is generally divided into hot air and flue gas. After the heat-carrier by the dryer, generally need the cyclone to trap the material of the gas down. Through the bag filter or wet dust collector and then put emissions, if you want to reduce dust content of exhaust gas.
