Abstract

This invention relates to methods for the enrichment of fine minerals, in particular, to gravity enrichment methods. The goal is to increase the efficiency of the device by increasing the time directly enrichment by combining basic and preparatory operations. On the disk support 3 there is a conic bowl (RC) 4 with flanges and with removable grooves (P) 5. In the upper part of RC 4 there is a circular tray 6 for dumping the tails. A sieve (C) 8 is fixed inside QC 4 with a gap, fixed rigidly on QC 4 flanges with fasteners 9 and repeating its dimensions. The gap H between the inner wall of CN 4 and C 8 is associated with the height P 5 H by the ratio H≥2H. The power supply C 8 is supplied via a funnel supply funnel 7 coaxially located above QC 4. By means of drive 1 with gearbox 2 rotation is applied through drive shaft QF 4. The coarse fraction with C 8 and the light fraction after enrichment at cn 4 come to circular tray 6. The concentrate is collected in P 5, from which it is periodically discharged. 2 Il.

Description

The decree refers to the use of the enrichment of finely divided minerals, in particular gravity enrichment methods, and can be used to refine more bulk samples, in particular geological ones.

The purpose of the invention is to increase the efficiency of the device by increasing the time directly due to the combination of basic and preparatory operations.

FIG. 1 shows a centrifugal separator for the enrichment of fine-dispersed minerals, a general view; in fig. 2 — node I in FIG. one.

The separator includes a drive 1 with a gearbox 2 mounted on a drive shaft on a disk support 3 a conical bowl 4 with flanges and removable grooves 5, In the upper part of the conical bowl 4 there is a circular lotto 6 for dumping tails. A funnel-shaped feeding nozzle 7 is mounted coaxially with a conical bowl 4. A sieve 8 is fixed inside the conical bowl 4 with a gap. The sieve 8 repeats the dimensions of the conical bowl 4 and is rigidly connected with it on the flanges. The gap And between the screen 8 and the inner wall of the conical bowl 4 is associated with the height of the rifle h by the ratio H 2h. The sieve 8 is connected to a conical bowl with 4 fasteners 9.

The separator is located on frame 10.

The separator works as follows.

The actuator 1 rotates the gearbox and transmits the rotation to the shaft of the actuator on which the disk support 3 is fixed. On the disk support 3 a conic bowl 4 is fixed. The pulp is fed through a crow K (H 6pa: iiibi) i itH r.iioiunii pipe: / m mm- idaado i 8, where the iisho / guitreleiis to (lrlkg; i - iz i p oiiii) beforera rting. coarse fraction (n – yr n blah shtre: s circle 6), 6,, podsr pus product enters the environment to the enrichment of conical chmma 4,

there is a separation of the useful component. The xsncentrate is collected on flute x 3, from where it is washed off with water into the receiver after completion of work,

5 and the light fraction (tails) is carried to the dump through the circular tray 6.
