Research of the Dehydration Process of Amber- Containing Mining Mass

Abstract

The article highlights the results of research into the process of dehydration of amber-containing mining mass using a vibroclassifier. Features of the technological scheme of amber extraction are described, as it relates to water supply points. The state of equilibrium of the liquid in the cell of the vibroclassifier under different conditions of sieve wettability was studied: a liquid that does not wet the sieve fibers; liquid that wets the fibers of the sieve; a thin film of liquid that wets the sieve fibers. As a result of the research, it was established that in the case when the liquid does not wet the fibers of the sieve, the height of the layer of liquid that is maximally retained in the cell is at least 3 times greater than in the case of the liquid that wets the fibers of the sieve. The reliability of the obtained results is confirmed by the use of proven research methods and a relative error between calculated and experimental values at the level of 20%.
