SU923607A1 - Self-propelled sorting apparatus - Google Patents

Description

The invention relates to installations for grinding materials.

Closest to the proposed. is a self-propelled sorting installation, which includes a bunker, a rotary feeder — screen, GN conveyors.

The disadvantage of this solution is-. The low efficiency of the overburden grinding process of the enriched mineral component is low.

The purpose of the invention is to increase the efficiency of the process of extraction from overburden enriched useful component.

This goal is achieved by that in a self-propelled sorting plant, including a bunker, a rotary feeder - screen, conveyors, the bunker in its lower part is equipped with a gear element with an eccentric drive.

FIG. 1 shows a self-propelled sorting plant, general, type; in fig. 2 - gear element

The primary crushing processing unit includes a hopper 1, an inclined plane 2, a pit 3, a vibrating element Λ with teeth 5, driven into oscillatory motion by an eccentric drive 6 acting on the levers 7 mounted on an axis 8, and a damping device 9, a rotary feeder 10 screen , tray 11, vibratory jaw crusher 12, conveyor 13, tray 14, vibrating rotary screen 15, tray 16, conveyor 1? and aspiration shelter 18.

Primary processing unit. crushing works as follows.

The original mountain race is fed into the receiving bunker 1 and along an inclined plane 2 enters the first stage of processing into the loading pit 3 ·

As a result of rotation of the working screening, transporting over 923607 4

of the rotary feeder 10 and the oscillation of the vibrating nozzle 4 s with ^x teeth 5, the mountain mass comes into active movement, intensively mixed, loosened and suspended. Large pieces (oversize product) in size, for example; more, e 300 mm are forcibly lifted from the lower part of the loading sump 3 by the transporting screening surface of the rotary feeder - screen 10 to its upper point, passing its way through the oscillating mountain mass in suspension, it is additionally loosened and simultaneously cleaned - large pieces of rock rocks from particles of earth, sand and clay inclusions.

Upon further rotation of the rotor, large rock pieces arrive at the chute 11 and follow it to the vibratory jaw crusher 12 with a receiving window of 1200x1500 mm, after crushing they go to the conveyor 13 and follow to the secondary crushing workshop.

Undersized loosened rock, containing impurities of earth, sand, clay inclusions and rocks, syabye in strength from under the rotary feeder - screen -10 enters tray 14 and follows it to the second stage of processing, to the vibrating rotor screen 15, where the release takes place of the remaining even more loosened rock mass of small cleaned pieces of rock, which along tray 16 follow smoothly onto conveyor 13 and, on the way, serve as underlying protective layer of conveyor belt

conveyor belt 13 at. 'the fall of unbroken sharp pieces of rock from a vibratory slit draw. bills 12.

5 After the second stage of processing, the friable mountainous mass is produced from a vibratory rotary screen 15 containing inclusions of earth, sand, clay and small rocks, weak in strength and unsuitable for further use, is fed to the conveyor 17 and transported to the dump.

Thus, as a result of the application of the equipment described above and the corresponding technology of two-stage processing of the original rock mass, characterized by the presence of inclusions of clay impurities,

And the earth and rocks that are weak in strength, there is an opportunity to get the ob'-rubbed rubble.
