1Nickel oxide high-speed centrifugal spray dryeroverview

Nickel oxide is an inorganic compound with the chemical formula NiO. It is an olive green crystalline powder that is insoluble in water. It is mainly used as a bonding agent and coloring agent for enamel, as well as a pigment for ceramics and glass. It can also be used in the production of magnetic materials such as nickel zinc ferrite. It can also be used as a raw material for the production of nickel salts, nickel catalysts, and applied in metallurgy and cathode ray tubes.

3、 Principle of high-speed centrifugal spray dryer for nickel oxide

After the air passes through the filter and heating device, it enters the air inlet distributor at the top of the drying chamber. The hot air passing through the air inlet distributor enters the tower in a spiral shape evenly. At the same time, the screw pump sends the feed liquid to the centrifugal spray head installed on the top of the tower body. The feed liquid is atomized into tiny atomized liquid droplets, which greatly increases the surface area of the feed liquid and the hot air. The small liquid droplets and the hot air flow and sink together. The water evaporates rapidly and is dried into powder products in a very short time. It is captured in the tower bottom and the cyclone separator, and the waste gas is discharged to the outside.
