Abstract
A vibratory conveyor for forming flowable grain agglomerations from previously poorly flowable fine-grained powder and thereafter conveying said agglomerations to a metering chamber which comprises a mechanical vibration device to agglomerate the poorly flowable powder, transport means for conveying the agglomerated powder and metering means for collecting and measuring the conveyed powder; and a method directed thereto wherein the poorly flowable powder is subjected to a mechanical vibration step prior to transport and metering.
Claims6
A method for metering small quantities of a non-flowable or poorly flowable fine-grained powder which comprises the steps of (1) feeding said fine-grained powder to a mechanical vibration device, (2) mechanically vibrating said powder in said mechanical/vibration device to form flowable grain agglomerations, (3) transporting said agglomerations to a metering device, (4) metering the desired amounts of agglomerations and (5) collecting said metered amounts.
