Abstract
Pressurized air is applied to dry granular materials as they enter the top of a vessel to mix the materials together and the mixed materials continuously flow out of the vessel through a bottom discharge opening.
Claims5
Apparatus for mixing together two or more granular materials, comprising:
- (a) a vertically elongated container having an open discharge outlet at the bottom and a vertical center line;
- (b) inlet means for simultaneously feeding two or more granular materials into the top of said container so they tend to fall toward the bottom of the container;
- (c) means for applying pressurized gas upward and inward toward the vertical center line of the container into the falling granular materials while the granular materials are being fed into the container to cause turbulence within the container to mix the materials together;
- and
- (d) means within the container located above the discharge outlet for deflecting the granular materials from flowing in a direct path from said inlet means to said discharge outlet.

A method for pneumatically mixing together two or more granular materials comprising the steps of:
- (a) feeding at the same time two or more granular materials into the top of a container having a vertical center line;
- (b) applying streams of pressurized gas upward and inward toward the vertical center line of the container into the materials while they are falling into the container to create turbulence to mix the materials together;
- (c) continuously discharging the mixed granular materials through an opening in the bottom of the container;
- and
- (d) deflecting the granular materials as they fall from the top of the container toward the container bottom discharge opening for preventing the granular materials from falling in a straight path from the entry at the top of the container to the discharge opening.
