Centrifugal Atomizer Rotary Spray Dryer Granulator
Principles:
High Speed Rotary Spray Dryer Series of GPL is gas-liquid cocurrent flow drying equipment, using high-speed centrifugal atomizer, the liquid will be atomized into fine droplets, then mix with the hot air from the distributor in the dryer, heat and mass transfer exchanges rapidly during the mixing process. In a very short period of time the liquid become dry powdered products. Production control and product quality control is convenient and reliable. It is widely used in the drying production of different types of liquids materials.
Product Characteristics:
Different types of solution, suspension, emulsion and cream paste material can be dry for a one-time production.
The fog moment and fog droplet of spray-drying can be slightly adjusted.
The hot air has been reasonable allocation, and the ceiling and walls sticky situation has been eliminated.
It is suitable for the drying of thermosensitive and nonthermosensitive material at the same time. The product particles are smaller than pressure spray dryer.
Simplify the production process, easy to use, good liquidity and instant of the product.
Application Examples:
Inorganic: aluminum nitride, zirconia, potassium fluoride, bentonite, kaolin, barium sulfate, lead sulfate, sodium aluminum, chromium oxide, titanium dioxide.
Macromolecule polymers: urea-formaldehyde resin, PVC.
Dyes: dispersol red FB, reactive dyes, etc.
Chemical Agents: silica dioxide, diatomite, sodium silicate, wood calcium, sodium ligninsulfonate, naphthalene series water reducer.
