Annotation:

The paper analyses research on dehydration of mountain mass at vibrating screens. The design of experimental model of screen and technique of realization of experiments is described. Dependence of process of passage of liquid through cells of a sieve from frequency and amplitude on shock influence on various sifting surfaces is investigated. Comparison of various sifting surfaces by difference of water residue is executed. Connection between the water residue and scope of fluctuation of the hammer is established.
