METHOD AND DEVICE FOR CLASSIFICATION OF MATERIAL PARTICLES IN FLOW OF HYDRAULIC FLUID Russian patent published in 1999 - IPC

FIELD: separation of solid material in liquid medium, applicable for concentration of mineral resources in mining and chemical industries, as well as in production of building materials. SUBSTANCE: flow of hydraulic fluid in pipeline is influenced by magnetic and electric fields with a strength equal to the breakdown strength with a boundary size. Flow of hydraulic fluid is separated by longitudinal parallel jets with simultaneous superposition of vibration field by means of a self-contained stack of parallel plates in the form of opposite electrodes attached by means of studs to the plate bearing against the pipeline and furnished with a vibration exciter. The upper section of the pipeline has longitudinal parallel slots receiving the plates of the self-contained stack of plates for extraction. The lower section of the pipeline has a tapered bottom and is furnished with a discharge valve. EFFECT: enhanced efficiency of material separation into magnetic and non-magnetic particles with any stoppage of flow of hydraulic fluid. 2 cl, 8 dwg
