Abstract
A method for producing material powder, comprising providing material and an atomization gas charged with an atomization gas pressure by means of an atomization gas compressor to an atomization device, melting the material and pulverizing the molten material into material powder by means of charging the molten material with the atomization gas using the atomization introducing the material powder from the atomization device into a pressurized container and providing a conveyor gas charged with a conveyer gas pressure by means of a conveyer gas compressor to the pressurized container, wherein the conveyor gas pressure is higher than the atmospheric pressure and lower than the atomization gas pressure, as well as a device for carrying out the method.
Claims14
A method for producing material powder, comprising the steps of:
- providing material and an atomization gas charged with an atomization pressure by means of an atomization gas compressor to an atomization device,
- melting the material pulverizing the molten material (5) into material powder by means of charging the molten material with the atomization gas using the atomization device;
- introducing the material powder from the atomization device into a pressurized container;
- characterized by
- providing a conveyor gas charged with a conveyor gas pressure by means of a conveyer gas compressor to the pressurized container, wherein the conveyor gas pressure is higher than the atmospheric pressure and lower than the atomization gas pressure.
A device for producing material powder having a conveyor gas compressor, an atomization gas compressor, an atomization device and a pressurized container, wherein the atomization gas compressor is configured to provide an atomization gas charged with an atomization gas pressure to the atomization device, wherein the atomization device is configured to melt a material and to charge the material powder with the atomization gas to atomize into material powder and to introduce the material powder into the pressurized container, characterized in that the device is configured to provide a conveyor gas charged with a conveyor gas pressure that is higher than the atmospheric pressure and lower than the atomization gas pressure by means of the conveyor gas compressor to the pressurized container.
