Centrifugal Atomization Powder Manufacturing Equipment with Small Gas Consumption

Centrifugal Atomization Equipment

1.Overview

The principle of rotating-disk centrifuge atomization technology refers to that metal liquid flows from melting furnace toward the center of high-speed rotating disk along through current-limiting guiding device, and then distributes radially, forming a molten metal thin membrane over rotating disk and this membrane reaching the edge of rotating disk under the effects of inertia and centrifugal force, and consequently the thin membrane is atomized into droplets and furthermore they are solidified into powder. With controlling the parameters of atomizing temperature and rotating speed of rotating disk, atomization can produce high-qualified non-hollow-bore powdered material with even particle size, good flow-ability and good arrangement.

Rotating-disk centrifugal atomization equipment is suitable for the production of metal and alloy powders with various melting points, such as solder, aluminum powder, magnesium powder, Sn-Pb powder, Sn-Zn powder, copper powder, stainless-steel powder and other spherical powdered materials.

2.Core Module Structure Technology

Rotating-disk centrifugal atomization equipment is consisted of melting furnace, high rotating-speed centrifugal atomizer, and atomized powder collecting barrel, etc.. Each module is precisely controlled by intelligent controlling system.
