Title:
POWDERY/GRANULAR MATERIAL FLUIDITY EVALUATING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2006/115145
Kind Code:
A1
Abstract:
A powdery/granular material fluidity evaluating device and method for evaluating the fluidity of a power in a dynamic powdery state. A powdery/granular material fluidity evaluating device (A) comprises hopper unit (111) for storing a powdery/granular material to be evaluated, a vertical pipe (11) the inlet (1121) of which is connected to the outlet (1112) of the hopper unit (111) from which the powdery/granular material is discharged, a vibrator (2) for vibrating the pipe (11), a laser vibrometer (3) for measuring the amplitude of the pipe (11), an electronic balance (4) for measuring the weight of the powdery/granular material having fallen from the hopper unit (111) through the pipe (11), and an evaluation value computing section (512) for computing the evaluation value for evaluating the fluidity of the powdery/granular material from the measured amplitude and weight.
