Abstract

The invention is intended for the separation of materials depending on the physicomechanical properties of the particles. The purpose of the invention is to increase the separation efficiency and reduce energy consumption. The material from the loading device enters the upper part of the deck8 inclined in the longitudinal direction8 made with inclined dividing sides on its longitudinal sides Above the deck with a gap relative to it is vertically mounted in the plane of its longitudinal axis the fender plate with the attached vibrodrive. on a pedestal. The flap plate, having made oscillatory movements in a vertical plane perpendicular to the longitudinal axis of the deck, drives the separated material located on the deck. Strong elastic particles, overcoming the forces of friction, jump over the sides of the deck and fall into the receivers located under the sides.

Description

The invention relates to devices for the separation of non-metallic materials depending on the physicomechanical properties of the particles representing this material, and can be used in the enrichment of rocks in the mining, coal, chemical industries and agriculture.

The aim of the invention is to increase the separation efficiency and reduce energy consumption,

The vibratory separator consists of a loading device comprising a loading conveyor 1 and a chute 2, and a deck 3 inclined in the longitudinal direction with dividing boards 4 and 5 on its opposite longitudinal sides. Deca 3 is rigidly fixed to frame 6. Above deck 3, in the plane of its longitudinal axis, there is a vertical mounting plate 7 fixed to its upper part centered

The hinges 8 on the axis 9 mounted on the frame 6. Under the action of the vibration exciter 10, operating from the electric motor 11 and attached to the fender plate, the fender plate oscillates in bearings 8 in a vertical plane perpendicular to the longitudinal axis of the deck. Durable material is collected in a hopper 12 , weak rocks and contaminating impurities roll into a 13o hopper. Deca 3 is set at an angle to the horizon, and its sides 4 and 5 are inclined to the plane of the deck. | Tska in cross section has the shape of an arc of a circle with a radius equal to the height of the baffle plate plus a gap.

Vibrating separator works as follows.

Bulk material consisting of strong B and weak B rocks and contaminating impurities, via conveyor 1 through heat 2, enters the separator working element, i.e. the deck. The vibrating baffle plate 7 drives the separated material, which takes part in the movement not only along the deck, but also bounces from the baffle plate to the peripheral edges of the sides of the deck. Durable material. B, which has large elastic properties, develops great speed, and, having overcome the resistance of friction force, jumps over boards 4 and 5 of the deck and enters bunker 12. Various impurities and weak rocks C cannot develop sufficient speed to overcome friction forces and jump beyond deck limits. Rolling; force forces such material to return 4 s at the bottom of the deck, where this material continues its movement along the inclined deck made in the form of a gutter to the place of unloading into the bunker 13. "Strong rocks, which due to the imperfection of the grain shape cannot develop sufficient speed once to fly over the deck deck, continue to participate in the separation process as you move along the chute.

The technical parameters of the vibration separator depend on the composition
