Aluminum Hydroxide Can be Dried by OSC-AST Air Swept Tublar Dryer?

Preface
  In industrial product market, Supplier’s Aluminum Hydroxide is micro dry powder and require 0.5% moisture or less. In order to dry Aluminum Hydroxide, our OSC-AST air swept tubular dryer will be your best choice. Why we say so? Let’s start from production process of aluminum hydroxide. Micro aluminum hydroxide powder is produced from common industrial aluminum hydroxide after crushing and grinding. Then, dewatered filter cakes are formed after washing and purifying impurities. Some new production lines adopt direct decomposition method to produce micro sediment aluminum hydroxide powder. No matter which type production process, intermediate products are aluminum hydroxide filter cake with 20% to 30% moisture content.
  Aluminum hydroxide filter cake holds large viscosity and high attached water. Although outer appearance presents hard filter cake, it will form paste slurry state after continuous clapping.
  If you ask is there any dryer most suitable for drying aluminum hydroxide filter cake, it is OSC-AST air swept tubular dryer.
Advantages of OSC-AST Air Swept Tubular dryer for drying aluminum hydroxide filter cake
There are five major advantages for OSC dryer in drying Aluminum hydroxide filter cake:
1.     Environment friendly and efficient: Final products after drying are uniform powder and collected by material collector specially designed for exhaust gas purification and fine powder collection.
2.     Energy saving:　aluminum hydroxide exchange heat with air, blade and dryer wall during drying process. Exhaust heat and almost fully dried products will pass through pulse drying unit together. Materials will be dried by exhaust heat again, which guarantees drying efficiency and makes use of exhaust heat.
3.     Drying and crushing are finished in one machine. The reason why drying effect of traditional dryer is poor is because aluminum hydroxide always stick to wall and form lump. High-speed rotary wing shaft set inside OSC dryer can avoid wall sticking and crush materials at same time. Drying work can be done quickly.
4.     Save occupation area: Aluminum hydroxide filter cake is always dried in old workshops whose space is very limit. One of OSC-AST air swept tubular dryer’s major advantage is tiny body, short length and width.
5.     High automation level: control system of OSC-AST air swept tubular dryer can directly connect with DCS and PLC. We can provide HIM to realize continuous feeding, discharging and automatic running.
Real working case of OSC dryer in drying similar materials.
  You may ask, OSC is suitable to dry other similar raw materials? Answer is yes. Other typical raw materials include zirconium with 2000-mesh size. Intermediate product is also filter cake similar to Aluminum hydroxide. In Zhengzhou, there is one zirconium drying site.
 Besides, there is another one typical raw material that is gypsum. If you are interested, please refer to following explanation: Desulfurized Gypsum New Drying and Calcining Technology-OSC-AST Air Swept Tubular Dryer.
