Spray granulation dryer
Spray granulation dryer is widely used in monosodium glutamate tail liquid handling, alcohol tail liquid handling industry, waste re-use of better production equipment.
Spray granulation dryer is the key equipment of compound fertilizer production process, the device sets shotcrete, granulation, drying in one, within the classification adopted, returning materials, broken structure, advanced technology, low cost, large output, compact structure, the preferred equipment for fertilizer production. The device is also widely used in monosodium glutamate tail liquid handling, alcohol tail liquid processing industries, is also a waste re- use of better production equipment.
From the flue gas / hot air heat source (coal, fuel oil, gas, steam, electricity), the rotary cylinder drying host, solution / melt atomization system, separation device (cyclone wet scrubber, multi-stage cyclone),fans,screening,control systems and other components. Continuous operation. Spray granulation dryer liquid atomization system in the old-fashioned rotary cylinder dryer, conventional rotary cylinder shape of the product range.
Spray granulation dryer are widely used: compound fertilizer granulation, organic fertilizer granulation, sewage sludge granulation and drying. Working principle in the role of high- pressure pump, the molten liquid into the specially designed spray nozzle, atomized into small droplets and small particles within the nuclei in the rotating cylinder in contact, droplets adhere to the surface at high temperatures in the nuclei drying medium, the rapid completion of the heat and mass transfer process, the particles increases, particles are increased screening small particles back to as nucleation; some powdered materials, is returned as the nuclei. Advantage of the solution, dry granulation processing of high-temperature melt material at once.
Equipment operate stability, simple operation, long life. Low operating costs, high thermal efficiency. Products of good quality materials to make the trip rate. Single output. Typical materials of compound fertilizer, organic fertilizer, sewage treatment plant sludge.
