The Working Principle of Sand Dryer

Jul 16 2014

Sand dryer is also known as river sand dryer, yellow sand dryer, and quartz sand dryer. It is generally used for drying granular materials, especially, sand, river sand, yellow sand, quartz sand, and etc. Its drying effect is very good. Next I will introduce you the working principle of sand dryer:

1. Sand firstly be sent to the hopper by a belt conveyor or a bucket elevator, and then enter into the feeding mouth though feeding pipe. The slope angle of the feeding pipe must be greater than materials’ so that materials can flow into the sand dryer smoothly.

2. Sand dryer’s drum is a rotating cylinder who has a slightly inclined an angle with the horizontal. Materials are fed from the higher end of the cylinder, and the heating medium enters in from the lower end so that they can contact with each other countercurrent. However, materials and heat medium can also enter into the cylinder from the same side.

3. There are lifting plates on the cylinder wall. They are used to throw the materials up and make them form material curtain so that materials can contact heat carrying medium completely and drying effect is improved.

4. During materials move to the lower end by their own weight, wet materials directly or indirectly exchange heat with the heating medium so than the wet materials are dried. The dried materials go out from the discharging end, and then be sent by the belt or screw conveyor.

5. After the hot gas and the wet materials finish heat exchanging, they generally need be captured down by cyclone ash collector. Further reduce the dust in the exhaust gas, you should use the bag-type dust collector. After that, the exhausted gas can be sent outside.
