Electrostatic powder mixing

Abstract

A device has been developed which uses electrostatic forces to mix powders. This mixer has no moving parts, and the mixture it produces approaches a perfect mixture whereas mechanical devices can at best produce a random mixture. The device is described, as are experiments which exhibit its operation. Also included are a mathematical model describing the behavior of the device, suggestions for scale‐up procedures, and h discussion of some closely related concepts of mixing.
