The spray dryeris a kind of continuous and ordinary pressure dryers. It nebulizes theliquid with special equipment to make it contact with the hot air to bedried. It is commonly used to dry some heat-sensitive liquid,suspension and viscous liquids, such as milk Ball Mill For Gold, eggs, tannin and drugs. Inaddition, it is also used for the drying of fuel, intermediates, soappowder, and inorganic salts, etc.Features:1. The speed of drying is fast; after the nebulization, the surface areaof the liquid will be greatly increased and in the hot air flow, 95%-98% of the moisture can be evaporated. The drying time only requiresten seconds it is especially suitable for the drying of heat sensitivematerials.2. It has a wide application range, according to the characteristics ofthe material Cement Clinker Grinding Process, it can be dried with hot air or the cold granulation; theadaptability to the materials is strong;3. The operation is simple and stable, it is easy to control and to realize the automatic operation. The product dried by the spray dryer has good uniformity, mobility andsolubility and the products have high purity and good quality. Theproduction process is simplified to make it convenient to control theequipment. As for the liquid whose moisture content is 40-60% (themoisture content of some special materials can be up to 90%), it can bedried into the powdery or granular products. Moreover, after the drying,there is no need to conduct the crushing and screening, reducing theproduction processes, which is helpful to improve the product purity.The product particle size, bulk density, moisture can be adjusted withina certain range by changing the operating conditions.
