Abstract

This invention relates to the beneficiation of minerals. The goal is to increase the efficiency of material detailing and extract a valuable component. For this, in the upper part of the cylindrical body (CC) 1, a feed funnel 2 and a drain threshold 3 are installed, along the axis of the CC 1 - drive shaft 4 with tine bars 5. In the lower part of the CC 1, a device for unloading sands 6 is installed, in the upper part of CC1 - fender ring (OK) 7, as well as four nozzles (P) 8, mated to the feed funnel 2. Last mounted on the drive shaft 4. The length of П8 is equal to 0.8 thicker radius, OK 7 is set at a distance of 0.85 to 0 , 9 of the thickener radius, and the bottom edge of OK7 is located 0.5 m below the level of the drain threshold. The ore enters the funnel 2 and is distributed into four P8s rotating with the drive shaft 4. The pulp is divided into sand and sludge fractions. The sludge fraction is carried upwardly into the discharge and is discharged through the drain threshold 3. The sands shielded from the drain threshold 3 OK 7 are deposited on the bottom of CC1 and the tines 5 are fed to the device 6 for unloading the sands. 2 Il.

The invention relates to devices for the removal of thin sludges, clays, waste rock with a thickener discharge during mineral processing.

The purpose of the invention is to increase the efficiency of material removal and the extraction of a valuable component.

FIG. 1 shows a thickener-delamator, general view; in fig. 2 - the same, top view.

The thickener-declarant contains a cylindrical body 1 and a feed hopper 2 installed in the upper part of the cylindrical body 1 and a drain threshold 3. Along the axis of the cylindrical body 1 a drive shaft 4 is installed with tine arms 5. A fixture b is installed in the lower part of the cylindrical body 1 unloading sands. In the upper part of the cylindrical body 1, there is a burglar ring 7 and four nozzles 8 are installed, mated with a feed funnel 2. The latter is fixed to the drive shaft 4. The length of the nozzles 8 is equal to 0.8 of the thickener radius. The fender ring 7 is set at a distance of 0.85-0.9 of the thickener radius, and the lower edge of the fender ring 7 is located 0.5 m below the level of the drain threshold.

The thickener-declamator works as follows.

The ore enters the feed hopper 2 and is distributed to four nozzles 8, rotating together with the drive shaft 4 at a speed of one revolution in 6.3 minutes.

The pulp is divided into sand and slurry fractions. The sludge fraction is carried upward into the discharge and discharged through the drain threshold 3. The sands, shielded from the drain threshold 3 by the fender ring 7, are deposited on the bottom of the cylindrical body 1 and are fed to the sanding tool 6 by the rakes 5.
