摘要： A method and apparatus for mixing fine powdered materials without creating an objectionable dusty environment, which consists in placing an open-topped container on a scale, placing a hood over the open-topped container, and with the hood interior connected to a source of suction, successively pouring the materials to be mixed into the container through a hole in the top of the hood and proportioning the materials by means of the scale. With the container thus filled, its open-topped upper portion is inserted into the downwardly facing mouth of a tiltable mixing drum and secured thereto in such a manner that the container tightly closes the mouth of the mixing drum so that admixture of the drum contents during rotation of the drum can take place without dispersing dust or fine powder into the atmosphere.

摘要： A funnel securable to the uncovered top of a receptacle containing dry pulverized material is provided with an encircling skirt which coacts with the funnel to define a relatively closed zone encompassing the discharge mouth of the funnel. A hole in the skirt near its junction with the funnel enables that zone to be connected with a source of suction, so that upon inversion of the receptacle to which the funnel is secured, an open-topped container placed in said zone beneath the discharge mouth of the funnel can be filled with dry pulverized material from the receptacle without creating an objectionably dusty environment.
