PROBLEM TO BE SOLVED: To provide a device and method for measuring an ultrasonic disaggregation speed of filler in a form of particle aggregate. SOLUTION: The device includes a cyclic path 1 in which a flow 2 of particles suspended in a liquid 3 circulates. The cyclic path 1 includes a sample preparation device 10 for sending a sample to the cyclic path 1 in a form of the flow 2, a laser granulometer for measuring a size of the aggregate when the flow passes, and a continuous processing cell 30 having a destroying means 35 for destroying the aggregate when the flow 2 from the laser granulometer 20 passes. The cyclic path includes the processing cell 30 arranged between an outlet port 22 of the granulometer 20 and an inlet port 11 of the preparation device 10, and at least one valve 13, 33 formed to an open space for eliminating bubbles formed by destroying operation so that the flow 2 of the particles from the preparation device 10 passes through the laser granulometer 20 before entering the processing cell 30.
