The dust removal efficiency of the dust collector at Shengjing Sandstone Factory can reach 99.9%. The dust emissions filtered by our dust collector can achieve long-term stable operation at an emission concentration of ≤ 30 ㎎/Nm3, and can adapt to the requirements for PM2.5 emissions. Its main performance parameters include processing air volume, dust removal efficiency, emission concentration, pressure loss, air leakage rate, and steel consumption rate. Our company selects and designs dust removal equipment for users based on the actual situation of the manufacturer.

Precautions for purchasing bag filter from Shengjing Sand and Stone Factory:

1. It is difficult to collect fine dust, so a bag filter should be used, and polyester needle punched felt filter cloth with good filtering effect should be used; The compressed air pulse cleaning method is adopted, and the cleaning effect is good.

2. Each dust point is equipped with a dust hood, with the hood facing downwards towards the direction of dust diffusion, which is beneficial for dust collection. The gaps around the dust point should be sealed as much as possible to minimize the amount of air used for dust collection, thereby reducing equipment investment and energy consumption.

3. A spiral conveyor and a star shaped unloader with air locking function are installed at the bottom of the dust collector to collect the dust collected in the dust collector for easy recycling.

4. The dust hood should be as close as possible to the dust source and as airtight as possible without affecting production and maintenance.

Technical characteristics of dust collector for Shengjing stone crusher:

1. Dust removal can reach 99.9%

2. A reasonable cleaning procedure and cleaning cycle have improved the cleaning effect of the dust collector and the lifespan of the dust bag

3. The diversification of dust cleaning control methods can be determined according to different working conditions, with different dust cleaning methods; It can achieve composite offline pulse dust cleaning.

4. Bag filter, with the correct selection of filter materials and operating conditions, can capture gases with high dust concentration without the need for secondary dust removal. The emission concentration is less than 50mg/m3, meeting the allowable emission standards

5. When the bag filter is used for coal powder dust removal, it is also equipped with explosion-proof devices and operates. When used for dust removal on the top of the warehouse, it can be used without brackets, ash hoppers, and ash discharge devices

6. Different filter bag materials can be selected based on various properties of the material, such as acidity, alkalinity, high temperature, particle size, and electrical load tolerance, with a wide range of applications

Principle of dust collector in stone factory:

The dust containing gas enters the upper space of the filter chamber in a tangential direction. Large particles and condensed dust particles spin down the ash hopper along the cylinder wall under the action of centrifugal force. Small particle dust disperses in the gaps between the filter bags in the filter chamber and is blocked by the filter bag. Purified air passes through the filter wall and is collected in the clean room through the filter bag inlet on the flower plate, and is sucked in by the ventilation fan and discharged into the atmosphere.
