Abstract
The article presents the results of the study and analysis of the main structures of depositors. Identified the strengths and weaknesses of individual models. Structurally, the jigs are divided into two groups: movable and immovable sieve. It is believed that jigging machines with movable sieve offer better performance, require less water, but outcomes for them are worse than the jigging machine with a fixed sieve. Given the technical characteristics of the diaphragm jigging machines. Illuminated the depositors technical characteristics with a conical pul-sators. Most designs have a limited height undersize (running) part, which ensures machines compactness and ease of use in various condi-tions. A positive feature of the machine is the consistency of the diaphragm stroke, providing a "hard" mode pulsation environment.
