Beach pump station sunk basin overflow pocket is additionally communicated by gravity feed hydraulic transport with two or three points of open-pit working board to return excess pulp into lane and to accelerate tailing thaw and wash-off.

Concrete recycling plant

Concrete recycling plant comprises a screen, an electromagnet and a system of water treatment, and also three technological chains. The first chain is a preparatory one and comprises hoppers for storage of mixtures, concrete, bricks, asphalt delivered by motor transport. The second chain is technological and comprises a plant for screening of heavy metal, the electromagnet for its trapping, a plant for sifting of sand and its storage into a hopper as a filler and a crusher for separation of concrete pieces from reinforcement joined with the second electromagnet. The third chain is a finishing one and comprises a reserve hopper connected with an impact-reflecting mill connected with the third electromagnet, and also comprises two screens connected with a system of water treatment comprising a mixer with a unit of wood chips and organic components supply, then a unit of fractionating, from where the treated items are sent to a warehouse of secondary fillers. To separate concrete pieces from reinforcement, a jaw breaker is used, comprising an electric motor with a pulley, an eccentric, movable and fixed jaws and a discharge window.

Device, flotation machine equipped therewith and method of its operation

Invention relates to dispersion of suspensions. Device for dispersion of suspension (2) by at least one gas (7, 7a, 7b), particularly for flotation machine (100) comprises dispersing nozzle (10, 10'). The latter comprises the following components arranged one after another along suspension flow: suspension nozzle (3', 3", 3'") converging along the flow, mixing chamber (4) including said nozzle (3', 3", 3'"), mixing tube (5, 5') adjoining said mixing chamber (4) and converging along the flow, and at least one gas feed line (6, 6a, 6b) to feed at least one gas (7, 7a, 7b) into mixing chamber (4). Suspension nozzle (3", 3"') has at least N gas channels (31), larger than 3, connected with said gas feed line (6, 6a, 6b) to terminate at end side(3a", 3a'") of suspension nozzle (3", 3"') facing said mixing chamber (4). Device comprises A gas valves (V). Note here that N=A and everyone of N gas channels incorporates one gas control valve (V) to metre out gas (7a) fed to suspension (2) via appropriate gas channel (31).

Gas flow cleaning filter

Invention relates to gas cleaning and can be used to separate aerosol particles and condensate from gas flow, particularly, in cooling tower for reduction of water losses in recycling water supply systems. Filter comprises electrically isolated ioniser wires arranged around gas flow along its axis at pipe outlet. Precipitation lattice-structure electrode is arranged with clearance relative to ioniser wires composed of separate electrically isolated sectors located around ioniser wire structure. Every sector of precipitation electrode is equipped with earthing device connected with wind direction pickup. External wind inflow to gas flow and its cooling are performed by continuous control over wind direction and that over precipitation electrode sectors earthing.

Vertical circular magnetic separator to remove iron from coal ash and method of its application

Invention relates to magnetic separation, particularly to vertical circular magnetic separator for removal of iron from coal ash. Proposed separator consists of rotary ring 101, inductor 102, top magnet frame 103, bottom magnet frame 104, magnetic excitation coil 105, feed opening 106, tank for tails 107 and flushing device 109. Opening 106 feed coal ash for removal of iron therefrom while tank 107 serves for removal nonmagnetic particles left after removal of iron. Said top iron magnet frame 103 and bottom magnet frame 104 are arranged at inner and outer sides of lower part of rotary ring 101. Flushing device 109 is arranged above said rotary ring 101. Inductor 102 is arranged inside rotary ring 101. Magnetic excitation coil 105 is located at outer edges of said top iron magnet frame 103 and bottom magnet frame 104 to make a pair of magnetic poles to induce magnetic field in vertical direction where inductor 102 is composed by layers of steel plate cells. Every said cell is braided by wire with sharp prismatic angles. Proposed separator produces magnetic field intensity of at least 15.000 Gs.
