Description

2. The Deulamatrp of claim 1, which is based on the fact that the pipes of the Ilama outlet are located at a distance of 5d

The invention relates to the enrichment of minerals by gravity methods and can be used for the classification and desliming of crushed materials.

The aim of the invention is to improve the quality of the concentrate and increase the extraction of iron in the concentrate.

FIG. 1 depicts a declarator; in fig. 2 shows section A-A in FIG. one.

The separator consists of a bath 1, a loading device 2, made in the form of horizontal pipes with slit-like holes 3 on the sides, a drain chute 4 that secures the upper open bath tap, sludge receiving pipes 5 with a valve 6 at the outlet to regulate the discharge of pulp from a slurry fraction, a siphon device 7 for unloading sands, a spray system 8 for creating an upward flow of water, a damper 9, inclined shelves 10 mounted on a damper and along the perimeter of the upper part of the bath walls with a gap 11 to the walls of the bath n sedative, and reflectors 12, located on the walls of the bath and the sedative under the shelves. Reflectors prevent the upward flow of water into the gap 11.

The immersion depth of the loading device is no more than 0.4-0.6 m. The distance between the pipes of the loading and sludge receiving device I (5-10) d, the receiving pipes are elevated above the loading device to a height h (1 - 2) do

Slot-like openings exist on those sections of the pipes of the loading and Chamopanus devices that are limited to the damper.

to I Od and height from Id to 2d from the pipes of the loading device, where d is the diameter of the pipes of the loading device.

Deschlamator works as follows.

The original pulp enters the loading device 2 and, passing through the slit-like openings of the 3 tubes, forms a thin stream over the entire cross section of the bath 1. The slurry part of the pulp is discharged through the slurry-receiving tubes 5. A uniform distribution of material well washed by the upward flow of water occurs which improves the quality of the separation products.

Heavy particles under the influence of gravity precipitate at the bottom of the bath and form a layer of sand, which is continuously washed by the upward flow of water created by the sprinkling system 8. The sand, as it accumulates, is discharged using siphon devices 7 operating in automatic mode. Fine particles and sludges that have not been removed from the bath by the pipes 5 are carried to the upper layers and move from the center to the overflow threshold. Due to the damper 9, the path of the particles increases and heavy particles during the advance to the overflow threshold have time to settle into the lower layers of the advertiser, thereby reducing the loss of metal with tails.

Inclined shelves 10 contribute to the formation of vortex flows, affecting the delamination of the material. The heavy particles, rolling down the shelves 10, fall into the gap 11 between the housing and the shelves (where there is no elevating flow) and are deposited. Light particles are also carried away with a drain. The degree of separation of the material into fractions is increasing.
