Abstract
Disclosed herein are powder mixing apparatuses and methods that utilize the deagglomerizing and mixing effects of an air flow that impacts a flowing powder. The resulting powder can have smaller particle sizes and/or exhibit a more homogenous mixture than the premixed powder.
Claims19
A method of mixing a powder, the method comprising:
- providing a first premixed powder to a first powder input portion, the first powder input portion comprising a first dispensing device;
- mixing the first premixed powder in a first mixing portion, the first mixing portion comprising a first powder inlet, a first gas inlet, and a first mixing cavity;
- wherein the first dispensing device comprises a venturi tube configured to dispense the first premixed powder into the first mixing portion;
- wherein the first gas inlet is configured to provide a first flow of gas into the first mixing cavity, and the first powder inlet is configured to dispense the first premixed powder into the first mixing cavity;
- and wherein the first flow of gas and the first premixed powder interact in the first mixing cavity to form a first post-mixed powder, and further comprising providing the first post-mixed powder to a second powder input portion, the second powder input portion comprising a second dispensing device;
- mixing the first post-mixed powder in a second mixing portion, the second mixing portion comprising a second powder inlet, a second gas inlet, and a second mixing cavity;
- wherein the second dispensing device comprises a second opening configured to dispense the first post-mixed powder into the second mixing portion;
- wherein the second pas inlet is configured to provide a second flow of gas into the second mixing cavity, and the second powder inlet is configured to dispense the first post-mixed powder into the second mixing cavity;
- and wherein the second flow of gas and the first post-mixed powder interact in the second mixing cavity to form a second post-mixed powder.

A method of mixing a powder, the method comprising:
- providing a first premixed powder to a first powder input portion, the first powder input portion comprising a first dispensing device;
- mixing the first premixed powder in a first mixing portion, the first mixing portion comprising a first powder inlet, a first gas inlet, and a first mixing cavity;
- wherein the first dispensing device comprises a first opening configured to dispense the first premixed powder into the first mixing portion;
- wherein the first gas inlet is configured to provide a first flow of pressurized gas into the first mixing cavity, and the first powder inlet is configured to dispense the first premixed powder into the first mixing cavity;
- and wherein the first flow of pressurized gas and the first premixed powder interact in the first mixing cavity to form a first post-mixed powder, and further comprising providing the first post-mixed powder to a second powder input portion, the second powder input portion comprising a second dispensing device;
- mixing the first post-mixed powder in a second mixing portion, the second mixing portion comprising a second powder inlet, a second gas inlet, and a second mixing cavity;
- wherein the second dispensing device comprises a second opening configured to dispense the first post-mixed powder into the second mixing portion;
- wherein the second gas inlet is configured to provide a second flow of gas into the second mixing cavity, and the second powder inlet is configured to dispense the first post-mixed powder into the second mixing cavity;
- and wherein the second flow of gas and the first post-mixed powder interact in the second mixing cavity to form a second post-mixed powder.

A method of mixing a powder, the method comprising:
- dispensing a powder from a powder input portion through a venturi tube into a mixing portion;
- mixing the powder in the mixing portion, the mixing portion comprising a powder inlet, a gas inlet, and a mixing cavity;
- wherein the gas inlet is configured to provide a flow of compressed gas into the mixing cavity;
- and wherein the flow of compressed gas and the powder interact in the mixing cavity to form a mixed powder, and further comprising providing the mixed powder to a second powder input portion, the second powder input portion comprising a second dispensing device;
- mixing the mixed powder in a second mixing portion, the second mixing portion comprising a second powder inlet, a second gas inlet, and a second mixing cavity;
- wherein the second dispensing device comprises a second opening configured to dispense the first mixed powder into the second mixing portion;
- wherein the second gas inlet is configured to provide a second flow of gas into the second mixing cavity, and the second powder inlet is configured to dispense the first mixed powder into the second mixing cavity;
- and wherein the second flow of gas and the first mixed powder interact in the second mixing cavity to form a second mixed powder.
