SIZING SCREEN-CONCENTRATOR

摘要

FIELD: mining industry; equipment for minerals enrichment. ^ SUBSTANCE: the invention is pertaining to the field of mining industry, in particular, to the minerals enrichment with the help of the sizing screen-concentrator used for the minerals gravity enrichment and may be used for extraction of the useful components from the various grainy materials. The sizing screen-concentrator consists of: the duct with the sowing surface; the vibration exciter; the concentration component made in the form of the ribbed wear-proof coating with the transversal ribs and the longitudinal groove with the variable depth conjugated at the lower layer with the inter-rib cavities by means of the side holes. The transversal ribs have inclination in the direction of the longitudinal groove and the tilt in the direction of the sizing screen-concentrator loading. At that it is possible to change their quantity, height and the tilt angle. At the outlet end of the longitudinal groove there is the fixed concentrate collector. The duct and the sowing surface with the concentration component have the possibility to change the frequency and the amplitude of vibrations. The concentration component is made in the form of the thin-layer non-perforated plate, the transversal ribs on which made together with the plate. At that At that the plate is simultaneously used as the bottom of the longitudinal groove. The longitudinal groove has the side walls. The side holes are made in these walls. The thin-layer plate has the longitudinal walls vertically arranged and densely connected with the outer butts surfaces of the transversal ribs. The technical result of the invention is the increased efficiency of grading and the gravity concentration of minerals. ^ EFFECT: the invention ensures the increased efficiency of grading and the gravity concentration of minerals. ^ 2 dwg
