More Information
Summary:The invention relates to an apparatus for measuring the static charge developed by a flowable solid as it passes through a conduit. The apparatus comprises a receptacle for receiving a sample of a flowable solid, a conduit for conveying the flowable solid and a device for measuring the static charge of the flowable solid as it exits the conduit. A method for measuring the static charge of a flowable solid is also provided. An apparatus for measuring and a method for controlling the static charge developed by a flowable solid as it passes through a conduit. The flowable solid is conveyed through the conduit in such a manner that the powder develops a static charge due to the triboelectric effect as it moves against the conduit walls. The static charge on the solid is then measured using a static charge measuring device such as a Faraday drum or cage.
