Gas atomization powder manufacturing equipment is characterized by small environmental pollution, high degree of ball-shape powder, low oxygen content and fast cooling rate and so on. Through many years’ constant innovation and improvement, our company has updated our gas atomization powder-manufacturing technique and technology several times in order to produce metal and alloy powders of high performance. Currently, the technology has become the leading factor to support and promote atomization powder-manufacturing equipment, new material research and new technology development.

2.Specifications
Radio-frequency plasma torch balling powder producing equipment is constructed with following seven components and peripheral components:
1.Radio-frequency plasma torch;
2.Radio-frequency plasma power supply;
3.Gas supplying and powder feeding system;
4.Reaction room and collection room, frame as well;
5.Vacuum pumping system;
6.Electric controlling and measuring system;
7.Cooling water machine unit.
Radio-frequency plasma torch:
It is the core key technology of the entire equipment, possessing proprietary intellectual property right. And it applies ceramic constraining pipe and divergent nozzles, allowing its performances under inert gas, reduction and oxidation environment.
High-frequency plasma power supply:
Power 100KW, frequency 3.0±0.5MHz.
Gas sending and powder feeding system:
Powder feeding device adopts an imported product made by ourselves, and it sends powder material into plasma torch. The diameters of sent powder particles are 10-200µm; on the other hand, gas supplying system applies precise float flowmeter (4 road), providing working gas (argon) for the torch. Reaction room, gathering room and frame: reaction room and gathering room utilize double-layer water cooling structure, and they are made of stainless steel, entirely adopting vacuum sealing pattern; the frame is spray-painted by carbon steel, partial materials are aluminum alloy which are strong, hard, steady and safe.
Air pumping system:
It is equipped with water-circulating vacuum pump + mechanical pump + lobe pump + regulating valve + pipes + corrugated bellows, and switched to maintain required loading voltage for booting the system its operation. Extreme vacuum is 8 x 10-2Pa.
Electric controlling and measuring system:
Temperature and pressure measurement, regulation on filter back flushing, powder sending control, and gas flow.
Industrial cooling water machine unit:
30P, adopting air cooling pattern and providing clean cooling water for power supply and plasma torch.
