Title: Pneumatic static mixer
Inventor: ELLAM DONOVAN GRAHAM
IPC: B01F33/40
Filed: 1990-03-30
Abstract: By using tangentially mounted, compressed air jets to create a spiral action on material falling down a pipe a thorough mixing effect can be obtained. The compressed air additionally will force the mixture down the pipe to a delivery site. The weight of the materials falling from the hopper funnel will prevent any compressed air rising out of the funnel. A static, solid, circular core prevents the formation of a non-mixing zone in the centre of the mixing site. This core need not extend much beyond the mixing jets. The mixer may be mounted on a trailer. <IMAGE>
