Rotary Dryer for SAND
Application of sand dryer
The sand dryer is designed for the production of dry sand of a drum dryer, through a variety of properties of sand, the sand dryer to optimize the design for a wide range of low moisture content available.Sand finished and drying with excellent results. sand dryer is widely used in sand and building sand drying, successfully applied to the dry mortar, construction, new materials and other industries.

Working principle of sand dryer
Sand sent to the hopper by the belt conveyer and bucket elevator, and then through the hopper feeder into the feeding pipe, thereby entering the feeding end. The sand dryer feeding pipe inclination is greater than the natural angle of materials, so that material flows into the sand dryer.Dryer cylinder is a rotating cylinder that have a certain inclination with horizontal line. Material from the high-end to join, heat carrier from the low-end entry, countercurrent contact with material, also have heat carrier and material flow into the cylinder together. With the rotating cylinder materials by gravity run to the lower end. Wet material in the cylinder body to move forward, heat by heat carrier directly or indirectly, so that the wet material to be dried, then at the discharge end through a belt or a screw conveyor send out. In sand dryer inner wall of the cylinder is provided with a copy board. Its role is to bring up material then down, increasing the contract surface of material and gas flow, in order to improve the drying rate and promote material progress. Heat carrier are generally divided into hot air, flue gas. Heat carrier through the dryer, then the material in the gas was collected by cyclone dust collector. If need to further reduce the exhaust gas dust content,also should dust by the bag dust collector.
