Sand Dryer(Sand Drying Machine) Application:
and drying machine called rotary drum dryer for short which can handle a large number of materials.As the operation reliability, operating flexibility, adaptability, handling large, widely used in building materials, metallurgy, food, chemical, coal, medicine and mining industries.Rotary dryer generally adapted to granular materials, but also can dry sticky paste-like material by the method of partly mixing materials or a high moisture content materials.

Sand Dryer(Sand Drying Machine) Features:
In particular the sand dryer , rotary drum dryer hold an impressive effect.The advantage of Rotary drum dryer is large capacity,suitable for a wide range, low flow resistance, allowance of large range fluctuation in operation , easy to operate and so on.Commonly used in drying sand, slag, cinder and so on.
Sand Dryer(Sand Drying Machine) Sturcture:
and drying machine mainly by: 1, cylinder; 2, pre-roll ring; three post-roll ring; 4, gear; 5, block roller; 6, drag roll; 7, the small gear; 8,a material part; 9; Yang board; 10, speed reducer; 11, motor; 12, sirocco Road, 13, feed chute; 14, furnace body and other components.In addition,gas producer, the combustion chamber, or auxiliary hoisting machine, belt conveyor, quantitative feeder, cyclone dust collector, induced draft fan and so on also can be designed according to user needs
Sand Dryer(Sand Drying Machine) Working Principle:
Sand is sent to the hopper by the belt conveyor or bucket hoisting machine , and then it is delivering to the feed side through the feed pipeline by the action of hopper's feed machine.The slope of the feed pipeline should be greater than the natural angle of the material in order to make the material inflow to the dryer smoothly.Dryer cylinder is a rotating cylinder which is has a slight angle to the horizon.Material is fed from the higher end and the heat carrier is fed from the lower end.Thus contact with the material in the counter-current way.Material is run to the other lower bottom by gravity when the cylinder is rotating .Wet material gain heat from the heat carrier directly or indirectly when it move forward.Then the wet material become dry material and sent our at the discharged end by belt or screw conveyor.There is a shovelling plate in the inwall of the cylinder.It is used to raise up and down in order to enlarge the connect surface between the material and airflow , improve the rate of the drying and push the material forward. .Heat-carrying agent is generally divided into hot air, flue gas and so on.After

going through the dryer, the heat carrier normally need the cyclone dust separator to catch the material which is in the gas.For further reduction the dust content in the offgas,it also should go through the bag-patten dust catcher or hydrofilter before release.
