The Dynamic Measurement of the Physical Properties of Powders Using Vibration – the Mixing Effect of a Small Amount of Fine Powder [Translated]†

概要

論文の詳細を見る
A vibrational tester for measuring the dynamic physical properties of powders has been developed. The tester system consists of an electromagnetic vibrator with a controller for frequency and acceleration, a solid sphere sensor attached to a load transducer, and a microcomputer. It has been shown that the characteristic curves, when measured as the relationship between the frequency and the vertically transmitted force through the powder bed, are sensitive to changes in the physical properties of the powders. The mixing effect of a small amount of fine powder on the change in the peaks of the characteristic frequency has been measured using two different mixers.† This report was originally printed in J.
