Sand dryer product description:
Sand dryer is also used as sand drying machine, dryer is a kind of processing of large amounts of material. Due to the reliable operation, large elasticity of operation, strong adaptability, large capacity, widely used in building material, metallurgy, food, chemical, coal, medicine in the mining industry. Sand dryer, or sand dryer drum dryer. Generally suitable for granular materials, can also be used for some methods to mixed materials dry glue paste materials or materials moisture content is higher. Especially dry sand, sand dryer drying excellent results. Sand dryer or sand dryer has the advantage of high production capacity, wide applicable range, small flow resistance, operating on the allowed range is bigger, easy to operate, etc.
Sand dryer works:
Sand by belt conveyor or bucket elevator to the hopper, and then through the hopper feeder through the feeding tube into the feed end. The feed pipe slope should be greater than the natural inclination of materials, so that the material flows into the sand dryer smoothly (sand dryer). The dryer cylinder is a horizontal tilt slightly into the rotary cylinder. Material from high end to join, heating medium from low-end to enter, and material into a counter-current contact, there is also a heating medium with materials and flow into the cylinder. With the rotation of the cylinder material by gravity to run to the bottom on the lower side. Wet materials in the process of cylinder body move forward, directly or indirectly, to get the heating medium, make the wet material to dry, then by belt conveyor or screw conveyor at the discharge end. (sand dryer) in sand dryer cylinder wall with copy board, its role is to put the material copy up and again, the contact surface is increased and the air flow of material, in order to improve the drying rate and promote the material progress. Heating medium is generally divided into the hot air and flue gas, etc. After heating medium by the dryer, generally need to cyclone with materials in the gas trap. For further reducing exhaust dust content, but also put again after a bag filter or wet precipitator emissions.
Composition is sio2 is usually in the form of quartz sand, its stable chemical properties and quality of a material is solid, enough resistance to weathering.
Sand is composed of minerals and small rock fragments. Rock fragments is through erosion and weathering. The sand composition varies from place to place.
Feldspar sandstone is a kind of feldspar (aluminum silicate) high content of sand or sandstone, usually near the granite formed by weathering and erosion.
Sand is pure natural substances or mechanism sand, contains a lot of water and magazine, sand dryer, is undoubtedly have solved the problem of sand dehumidification, tedious work to reduce the burden for us. Dryer adopts the advanced technology, in combination with the practical situation of domestic sand industry developed efficient drying equipment, it has reasonable structure, greatly reduce the failure rate.
