China best-selling Slag rotary dryer with favourable price
What is slag dryer?
Slag dryer is mainly made up by the rotating cylinder, the wind equipment, high-speed broken up equipment, lifting plate, self cleaning device, transmission, transportation equipment, air equipment, reduction gear, support equipment and sealing devices and other parts. It has features of reasonable design, perfectly produced, stable performance, advanced technology, high output, low energy consumption, small floor area, and higher degree of mechanization.
How does the slag dryer work ?
1. The slag was sent to hopper by belt conveyor or bucket elevator and then by the feeding machine of hopper through charging pipe into the feeding side.
2. The slope of feeding pipeline should bigger than the materials' natural dip angle, in order to materials smoothly flow into the mining dryer machine.
3. The drum of dryer is a rotary drum which is slightly obliquely with the horizontal line. Add the materials from the higher side, heating body goes into the lower end, form countercurrent contact with materials, also exists the heat body and materials together concurrent flow into the barrel.
4. Along with the cylinder rotating, the materials move to the lower end by gravity. During the moving process, wet materials in the cylinder directly or indirectly got heat from the heating body, make wet materials to dry, then in the discharging end the materials were sent out by belt conveyor or screw conveyor.
5. In the cylinder's inside wall of slag dryer was equipped with shoveling plate, its function is that copied up the material and then scatter down, make the contact surface of materials and airflow more wider, in order to improve drying speed and promote materials move ahead.
6. Heat body are generally classified into the hot air and flue gas etc. After the heat body through dryer, generally need the cyclone dust collector to trap materials in the gas. If you want to reduce tail gas dust load any further, also should pass bag filters or dust washer, then let out.
What the difference between different type of slag dryers?
Specification (m) | Capacity (t/h) | Moisture of feeding materials (%) | Moisture of discharging materials (%) | Power (KW) |
Φ1.5x14 | 10-12 | 20±3 | ≤10 | 15 |
Φ1.8x14 | 15-18 | 20±3 | ≤10 | 18.5 |
Φ2.0x16 | 20-25 | 20±3 | ≤10 | 18.5 |
Φ2.2x18 | 25-30 | 20±3 | ≤10 | 22 |
