Abstract:

: Effectiveness of the vibratory and technologic processes of the sticky friable materials depends on degree of penetration of vibrations in them and characteristics of the working member bottom.A mathematical model of the friable material vibro-separation process on the vibro-feeder bottom with a net, considering elastic characteristics of the net, is presented in the work. Mathematical modeling of the process is carried out and the results of solution are shown, when the vibrations transmitted from the vibro-feeder and elastic deformations of the net are acting on the material simultaneously. Penetration of vibrations in friable materials is studied on the vibratory test bench and vibratory machine and some results are given.
