Particle measuring instrument, in particular for the analysis of grain sizes of fine and very fine bulk materials

摘要

Particle measuring instrument and method for the analysis of particles comprising a dosing device which dosing device can be set into vibrations by means of a vibration generator for conveying, while segregating, particles present in the dosing chute to at least one outlet of the dosing device. Other than a first vibration generator a second, different vibration generator is provided for segregating the particles present in the dosing device. The second vibration generator generates vibrations of a higher frequency compared to the first vibration generator.

1. A particle measuring instrument for the analysis of particles comprising at least one substantially horizontally aligned dosing device which dosing device is set into vibrations at least in part by means of a first vibration generator for conveying while segregating the particles present in the dosing device substantially horizontally to at least one outlet of the dosing device, characterized in that other than a first vibration generator a second, different vibration generator is provided for further segregating the particles present in the dosing device wherein the second vibration generator is configured as an ultrasonic generator which is periodically adjustable within specified frequencies and is provided to generate vibrations of a higher frequency compared to the first vibration generator, whereby the entire dosing device is set to high-frequency vibration causing any particle agglomerates and persistently sticking baking at the dosing device to dissolve.
