For various materials, rapid generation of results is always critical. Particle-size analysis of processing products using a laser-based particle-size analyzer is a valid alternative to the traditional sizing test. The article presents the results of studies conducted using Microsizer 201C equipment by the example of layered aluminosilicates and metal powders for additive manufacturing. The size analysis for these products is generally complicated by their ability to stick and agglomerate. Ultrasonic mixing does not harm the material analyzed and promotes uniform distribution of the sample during analysis. The results of granulometric analysis of kaolin ores obtained after different heat treatment are presented. The results of air-electric classification of metal powders obtained after vibration disintegration of metal chips are presented. The variety of raw materials shows a wide range of applications of this method in industry.

Flotation and foam separation processes are used in the beneficiation of ores containing layered silicates. The difficulties that arise with such beneficiation can complicate the overall concentration process. It is important that the process of flotation and foam separation occur under conditions of initiated or simultaneously imposed vibration. Such vibration can affect the behavior of the suspension (negatively or positively). Studying the vibration parameters applied to the suspension can help solve technological problems that arise during the concentration of ores containing layered silicates. In the present work, the behavior of a three-phase colloidal system under conditions of oscillation of a vessel with an external vibration exciter is studied.
