Sand dryer product description:
　Sand dryer is also used as a yellow sand dryer, it is a kind of processing a large number of material of dryer. Due to the reliable operation and large elasticity of operation, strong adaptability, large in capacity, widely used in building material, metallurgy, food, chemical, coal, medicine in the mining industry. Sand dryer, or yellow sand dryer of drum dryer. General adaptation in granular material, also can be used for part of the incorporation of the material to dry stick shaped paste material or water content higher material. Especially dry sand, sand dryer drying effect is excellent. Sand dryer or yellow sand dryer has the advantage of production capacity, wide range, flow resistance is small, operation allows larger fluctuation range, convenient operation, etc.
Sand drying machine working principle:
　Sand by belt conveyor or bucket elevator to the hopper, and then the hopper of feeding machine through the feed pipe into the feed end. Feed pipe slope than material of natural dip Angle, so that the material smoothly into the sand dryer (yellow sand dryer) inside. Dryer cylinder is a slightly into with the horizontal tilt of the rotating cylinder. Material from the higher end to join, heat carrier by low enter, and material into current contact, also have heating medium and material together and flow into the cylinder body. With the rotation of the cylinder material by the action of gravity operation to a bottom end. Wet material in the cylinder body move forward process, directly or indirectly got the heat carrier to, make the wet material have to dry, then in the discharge end by belt conveyor or screw conveyor send out. In the sand dryer (yellow sand dryer) on the cylinder body with copy board, its role is to copy material up and then, make the material and the airflow contact surface increases, in order to improve the drying rate and promote the material progress. Heat carrier generally divided into the hot air and flue gas, etc. Heat carrier the dryer later, general need cyclone in the gas with material capture down. If you need further reduce exhaust dust load, still should after bag-type collector or wet precipitator put again after discharge.
　The composition of the sand for silica is usually in the form of quartz, its chemical properties stability and quality of a material is solid enough to resistance to weathering.
By mineral sand and small rocks of debris. Rock fragments is rock after erosion and weathering and become. The sand composition varies from place to place.
Feldspar sandstone is a kind of feldspar (aluminum silicate) high content of sand or sandstone, usually nearby granite after weathering and erosion of the formation.
Sand is pure natural material or mechanism sand, contains a lot of moisture and magazines, sand the appearance of the dryer, it is to solve the problem of the sand dehumidification, for our tedious work to reduce the burden. Dryer adopts advanced technology, combined with the actual situation of domestic sandstone industry developed efficient drying equipment, it has reasonable structure, greatly reduce failure rate.
