Abstract: 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.

Abstract: In a method of drying particles of bulk material for subsequent transfer to an analyzer for determining a grain size of the particles, a free-flowing particle stream of particles to be dried is formed to move in a transport direction through a drying zone. As it moves through the drying zone, the particle stream is exposed to an air flow which is generated by a fan and heated by an air heater.
