The difference between the ultra-fine powder dryer and the flash dryer 1 The difference in structure (1) The ultra-fine powder dryer stir-driving device has a speed of several thousand revolutions, while the flash machine has only a few hundred revolutions, so the ultra-fine powder dryer has Rotary flash dryers have unparalleled crushing capabilities.
(2) The direction of the air entering the flash dryer is tangential air inlet, and the rotating wind speed in the drying section is determined by the air inlet speed, which is always an undefined value, and the ultra-fine powder dryer rotating wind speed is a high-speed rotating grinding disc. The rotating wind speed of the power is not affected by the system, thus ensuring reliable production and stable product quality.
(3) The feeding device of the ultra-fine powder dryer is a unique double-helical structure with smooth feeding: the continuously variable transmission is new and ensures the reliability of working at very low speed. The feeding device on the flasher is different from this unit.
(4) The classification device of the ultrafine powder dryer is a rotating device with adjustable speed, and the classification device of the flashing machine is actually only a classification ring. Although the rotary flash dryer is also improved, the classification ability is not as good. Ultrafine powder dryer.
2The difference in performance (1) The ultrafine powder dryer controls the moisture content and fineness of the dry material better than the flash machine. The fineness of the materials of the flash dryer can only reach a certain extent and cannot be further controlled.
(2) Since the pulverizing function of the ultrafine powder dryer is much better than that of the flashing machine, the output is larger than that of the flashing machine, and the product granularity is finer.
(3) The thermal efficiency of the ultrafine powder dryer in drying is obviously higher than that of the flashing machine, so the energy saving is obvious.
3 The advantages of using ultra-fine powder dryer in comprehensive comparison of drying effect are:
(1) Small size and small footprint: small supporting equipment (such as fans, dust collectors, etc.).
(2) Power consumption is small, energy saving: 1000Kcal is required for every kilogram of water evaporated on the ultrafine powder dryer, and 1500Kcal is required for each kilogram of water evaporated on the flash dryer. .
(3) The output is large and the product is fine.
