Сoal enrichment

They are available in various sizes with a diameter of up to 5 m and a height of up to 16 m.

In addition to individual columns, it is possible to supply a complete flotation unit, including the flotation columns themselves, a reagent dosing unit and an automatic remote monitoring and control system for the operation of the flotation unit.

For the enrichment of coal with a grain size from 0.5 to 75 mm in a magnetite suspension.

Innovative design and high-quality construction materials, high performance, long service life and minimal operating costs. At the same time, highly efficient enrichment of coals of difficult and very difficult degree of enrichment is ensured.

They are supplied in various sizes of different modifications with a nominal capacity from 50 to 400 t/h for the initial coal and from 160 to 1320 m3/h for the initial pulp.

For enriching coals with a size from 1 to 150 mm.

The control of bed thickness, air pulsations and a number of other important parameters is fully automated, which ensures ease of control of the enrichment process and its high efficiency. At the same time, air pulsations are of a complex nonlinear nature, which makes it possible to expand the range of fineness of the enriched coal and significantly increase the efficiency of separation of small fractions.

The ability to optimize controlled parameters depending on fluctuations in the characteristics of the feedstock directly during operation, low energy consumption and operating costs, high productivity, reliability and durability.

They are supplied in various sizes with a nominal capacity from 5 to 700 t/h.

For dry enrichment of coal (mineral raw materials) with a grain size of up to 50 mm.

Low capital costs and the cost of the process; low energy intensity; no need for water and its purification; obtaining dry enrichment products; reducing the volume of transportation of high-ash rock mass.

Machines of two standard sizes:

- single-chamber, with a capacity of 50 t/h for coal enrichment of 6-50 mm (40 t/h when working on a class of -6 mm);

- double-deck, with a capacity of 100 t/h for coal enrichment of 6-50 mm (80 t/h when working on a class of -6 mm).

For enrichment of fine grades of coal with a grain size from 40 microns to 3 mm.

Due to their simplicity, efficiency, reliability and high productivity, they are widely used and used in hundreds of processing plants around the world.

They are supplied in various designs and block versions: four- and seven-turn; with one-, two-, three-way spirals; up to 10 units. in a unit with a common power distributor and a food removal system. It is used mainly for the enrichment of granular (0.15-3.0 mm) and fine sludge (0.04-0.15 mm). They provide separation of sludge at densities of 1.55-2.0 t/m3. The productivity of one spiral is from 0.5 to 9.0 t/h, depending on the size of the sludge.
