Plasma manufacturing spheroidizing powder (system) equipment and technology
Description
Contact Supplier
Function : Plasma as heat source, refractory metal, spheroidizing and densification of ceramic powder and plasma arc temperature above 15000 degrees, The raw powder particle surface melting quickly, in under the action of surface tension, powder rapid quenching cold, The spherical powder particles shrink spheroidizing, forming dense.
The production process:
1. Inside the plasma reactor, inert gas, atmosphere is pure, clean, prevent oxidation,
2, powder collecting tank wall have a cooling jacket, to avoid the heat of powder adhesive on the inner wall of the tank,
3, plasma arc temperature of 15000 degrees, powder rapid cooling under inert atmosphere, synthesis of powder particle size small, good dispersibility,
4, simple plasma process equipment and gas controlled, can prevent the powder pollution, is suitable for the preparation of high purity powder.
Configuration of equipment
1. Plasma balling milling equipment include: powder collecting cans, gas filters, plasma power supply, control cabinet, delivering powder implement, transfer boxes, cold water machine, power of 80 kw
Standard index
2. The powder by plasma arc processing 2.8-10 kg/h, conveying feed powder
powder range 5-200 um.
