 water atomization powder production equipment

1. Introduciton
The method of powder atomization machine is a kind of new technology in the powder metallurgy industry which was developed in recent years. It is with the characteristics of simple craft, easy to master technology, not easy oxidizing material, and high degree of automation.

powder atomization machine can be used to manufacture most of metal powder and its alloy powder with low production cost
powder atomization machine can be used to manufacture spherical or irregular powder
Because of rapid solidification without segregation phenomenon, many special alloy powder can be produced
powder atomization machine using right craft can make the powder particle size to achieve a required range

3. Structure
High pressure water atomization powder manufactuing equipment is consisted of the following parts:
Melting and tundish system, atomizing system, inert gas protection system, ultra-high pressure water system, powder collect dewatering and drying system, screening system, cooling water system, PLC control system, platform system, and so on.
1. Melting and tundish system
2. Atomizing system
3. Inert gas protection system
4. Ultra-high pressure water system
5. Cooling system
6. Control system
(1) Melting and tundish system
Actually it is a medium frequency induction melting furnace, which consists of shell, induction coil, temperature measuring equipment, tilting furnace device, etc. The shell is a frame structure, which is made of carbon steel and stainless steel. Induction loop is installed in the middle, and the crucible is placed in the induction coil and could do the melting and pouring. The tundish is installed in nozzle system for storing molten liquid metal and thermal insulation.
It is smaller than the melting crucible volume. The tundish holding furnace has its own heating system and temperature measuring system. The heating system of holding furnace has two ways of electric resistance heating and induction heating, and generally resistance heating temperature can reach 1000 °C and induction heating temperature can reach 1200 °C or higher, but be reasonable choice of crucible materials.
(2) Atomizing system
The atomization system is made up of nozzle, high pressure water pipe, valve, etc.
(3) Inert gas protection system
During the process of making powder, to reduce the oxidation of metals and alloys and to reduce the oxygen content of powder, we commonly spray a quantitative inert gas into the tower for atmosphere protection.
(4) Ultra-high pressure water system
The system is to provide high-pressure water for atomizing nozzle, and it is consisted of high pressure water pumps, water tanks, valves, high pressure hoses, busbar, etc.
(5) Cooling system
The complete device is equipped with water cooling system, which is essential. Cooling water temperature will be reflected on a second instrument in order to guarantee the security of device running.
(6) Control system
Control system is the operation control center of the equipment. All the operations and related data are transmitted to PLC of the system, and the results are displayed through the processing and preservation.
