Changzhou group similarities and differences between manufacturers supply: fast drying, flash drying equipment, hot air dryer. Drying Equipment Co., Ltd. Changzhou group similarities and differences between fast flash drying equipment, spin flash drying equipment plant in the introduction, absorption of foreign advanced technology on the basis of the new drying equipment; develop their own successful; aircraft of advanced technology, reasonable design, structure compact, a wide range of applications, production capacity, product quality, high efficiency, energy saving, a device drying, crushing, screening once; elimination of environmental pollution; overall performance reached the international advanced level of technology. Principle: hot air pipe by the population enters into stirring and crushing and drying chamber from the bottom of drier with suitable atomizing speed; material exerts strong shearing, blowing, floating and rotating effect; material by centrifugation, cut, collision, friction and particles; strengthen the heat and mass transfer. In the the dryer lower part; larger damp granule action of stirrer was crushed; lower moisture content, particle size smaller particles are rotated entrained rise, further drying during ascent. Gas-solid flow in rotating; inertia of the solid phase is greater than the gas phase; solid-gas relative velocity of the two phases; strengthen the two phases of heat and mass transfer, so it strengthens. Features: feeding device for selection; continuous and stable feeding; the middle of the process does not produce bridge phenomenon. The lower part of the dryer set special cooling device; avoid the material in the high temperature zone of the lower part of the deterioration phenomenon. Special pneumatic sealing device and bearing cooling device; effectively extend the transmission part of the service life. Special sub-air devices; reduces the resistance of the device; effective dryer air volume. The drying chamber is equipped with a grading ring and swirl sheet; adjustable the materials fineness and final moisture. (Such as calcium carbonate final moisture adjustable to ≤ 0.1%) relative to other drying methods; can effectively increase the proportion of materials. Inside the drying chamber to the gas velocity; material residence time is short; effectively prevent the material viscosity and bi raw material deterioration phenomenon; achieve efficient, fast, small equipment, large-scale production.
