【Sand dryer 】
Sand dryer is called rotary drum dryer which is used for drying a wide variety of materials. It enjoys features of reliable operation, high operation flexibility, good adaptability, large capacity and widely used in the industries of metallurgy, building material, foodstuff, light industries, coal and chemical, etc. rotary drum dryer has good effect in drying granularity materials and some high water content, especially for sand. Rotating sand dryer has advantages of large productive capacity, wide application, small flow resistance, high operation flexibility, and easy operation,

Besides, according to user needs to design coal gasifier, combustion chamber or supporting elevator, belt conveyor, quantitative feeder, dust collector and draught fan etc.
【Working principle】
Sand was transported to the hopper by the belt conveyor or bucket elevator, and then enter into the feed end through the feeding tube by the hopper feeder. Slope of the feeding pipe must be greater than the natural angle of material so that the materials can flow into the sand dryer. Dryer cylinder forms a slightly tilted with the horizontal. Material was added from the higher to form reflux with the heat carrier entered from low-end. Sometimes, heat carrier flows into the cylinder together with the material. With the rotating of drum, material run to the lower end by gravity. In the moving process, wet materials obtain the heat input of heat carrier directly and indirectly to be dried, then, the finished materials are sent out by belt conveyor or screw conveyor.
The wall plate of cylinder body can lifting the materials up and down, increasing the contact area of material and air flow to improve the drying rate and promote the progression of materials, the heat carrier is generally classified into the hot air flue, gas flue, etc. dust cyclone need to capture down the materials carried by gas, if the dust content of off gas needs to be reduced in further, bag filter or wet dust also should be used.
