Changzhou group similarities and differences between manufacturers supply: the copper powder flash dryer, carbonate drying equipment, polyvinyl dryer. Drying Equipment Co., Ltd. Changzhou group similarities and differences Quick flash drying, spin flash drying equipment plant in the introduction, absorption of foreign advanced technology on the basis of; own successful development of the new drying equipment; the aircraft advanced technology, reasonable design, structure compact, wide application, production capacity, product quality, high-efficiency, energy-saving, a device drying, crushing, screening once; eliminate environmental pollution; overall performance reached the international advanced level of technology. Principle: hot air pipe by the population suitable atomizing speed from the bottom of the dryer into stirring and crushing and drying chamber; material exerts strong shearing, blowing, floating and rotating effect; material by centrifugation, shear, collision, friction is fine particles; strengthen the heat and mass transfer. In a lower portion of the dryer; larger wet granules corporation under the action of stirrer mechanical crushing; low moisture content, the particle size of the smaller particles is rotationally entrained to rise, further dried during ascent. Gas-solid flow in rotating; inertia of solid phase is greater than the gas phase; solid and gas phases relative speed; strengthen the two phases of heat and mass transfer, so it strengthens. Features: multiple feeding device for choice; feeding continuous and stable; the process middle bridge phenomenon does not produce. The lower part of the dryer to set a special cooling device; avoid deterioration phenomenon of the material in the lower part of the high-temperature zone. Special pneumatic sealing device and bearing cooling device; effectively extend the transmission part of the service life. Special air distribution device; reduce the resistance of the device; effective processing dryer air flow. The drying chamber is equipped with a grading ring and swirl piece; Material fineness and final moisture adjustable. (Such as calcium carbonate final moisture adjustable to ≤ 0.1%) relative to other drying methods; materials can effectively increase the proportion. Inside the drying chamber to the gas velocity; material residence time is short; effective prevent material sticking Pik and heat sensitive materials deterioration phenomenon; achieve efficient, fast, small equipment, large-scale production.
