Instruction:
In Salt Refineries, drying is one of the high energy consuming step. For drying of salt, hot air generated by coal or fossil fuel fired boiler with a heat exchanger is used. The air is heated from ambient to the temperature of around 160 Deg C. This hot air is forced in to a fluidized bed dryer where salt around 4 – 5% moisture is dried to a moisture of 0.2%
The residual moisture of the crystal sea-salt after its separation from the solution is usually from2.5-4.5%.At this moisture the product is unsuitable for grinding and therefore they should be dried up to a final moisture of 0.2-0.25%
ZLG series dryier is the best choice for drying .
Feature:
1. Height of fluidizing room and method of dust collection is by requirement.
2. The vibration is created by motor. It is stable in operation and convenient in maintenance, low noise and long life.
3. High efficiency, raw material is heated evenly and heat exchange is fully used and dry capacity is high. Compared with ordinary drier, the energy can be saved about 30%.
4. It is good in regulation and wide in suitability. The thickness of raw material layer and movable speed inside the machine and the amplitude can be adjusted.
5. It makes minimum damage to the surface of raw material. The equipment can be used for drying raw materials that are easy broken. The drying effect can not be affected even if raw materials have irregular shape.
6. Being adapted closed construction, protect raw material from cross-contamination effectively, it could continuous work.
7. When the raw material has high water content and large capacity, we could design the connection drying processing line.
Principle:
Raw material is fed into the machine from the inlet and moves forward continuously along with the level of fluid bed under the action of vibration. The hot air passes through fluid bed and carries out heat exchange with damp raw material. Then the damp air is exhausted out through cyclone separator and dry raw material is discharged through discharge outlet..
