OEM Pneumatic Conveyor Silo Pump Dense Phase Pneumatic Conveying System For Mineral Powder

High Operating Rate Dense Phase Pneumatic Conveying Silo Pump For Mineral Powder
 
Description
 

Dense Phase Pneumatic Conveying Silo Pump is a relatively reliable dense phase dynamic pressure pneumatic conveying device for conveying powdery materials under high pressure in pneumatic conveying equipment. It belongs to the energy-saving and environment-friendly pneumatic conveying device.

【Application field】

PCD pneumatic conveying equipment and systems have been widely used in building materials, chemical industry, mining, electric power, metallurgy and other industries. The conveying materials are: cement, raw meal, fly ash, slaked lime, dry-discharge carbide slag, slag powder, steel slag powder, coal powder, alumina powder, vitriol powder, phosphorus powder, pyrophyllite powder and organic silicon powder, etc.

【Product advantages】

①High mixing ratio: >30kg/kg;

②Large conveying capacity: >300t/h;

③Low speed: initial speed 6～10m/s;

④Low power consumption: <3.8kWh/t·km;

⑤Long distance: >2000m;

⑥ Small wear: pipeline life > 10 years;

⑦ Flexible process layout, no dust, high operation rate, lower investment and less maintenance cost than mechanical conveying

【Work Process】

1. Feeding stage.

Open the feed valve and exhaust valve, the material starts to enter the silo pump under normal pressure, and stops feeding after the material level gauge sends out the silo full indication signal;

2. Pressurized fluidization stage.

Close the feed valve and exhaust valve, and open the intake air valve to increase the pressure in the tank;

3. Delivery stage.

When the specified pressure is reached, the conveying air valve and the discharge valve are opened again to start the conveying of the material; when the conveying in the silo pump is completed, the pipeline resistance decreases, the pressure of the silo pump drops, and when it drops to the lower limit pressure, the material conveying state ends .

4. Purge stage.

After the pressure switch, material level gauge or time relay indicates that the conveying is over, close the high-pressure air valve and the discharge valve, open the secondary purge valve, and use all the compressed air to clean the residual material in the pipe. At this time, there is no residual material in the silo pump. The residual material in the pipeline begins to gradually decrease until it is in a state of air flow. The intake valve, the discharge valve and the secondary gas valve are closed, and a cycle is completed.
