Hello everyone, the editor will introduce the bag filter of the sand and gravel factory to you; Dust collector for gravel factory
Feixiang Company has adopted pulse bag dust removal technology in several major stages of the crushing, conveying, and screening processes that mainly generate dust in the sand and gravel factory. Our sand and gravel factory bag dust collector has a relatively complete and mature structure principle and dust cleaning technology.
The dust collector in the gravel factory has been applied in crushing and screening projects in various mines. It has the characteristics of tangential air intake, high-pressure air dust cleaning, external filter dust removal, good dust cleaning effect, fully enclosed filtration area, external maintenance and repair of the machine, and easy operation.

The first screening workshop, intermediate crushing workshop, second screening workshop, and fine crushing workshop are all equipped with a set of dust collectors for the stone mill. The dust collector in the stone factory adopts online pulse dust cleaning, which is a unit combination dust collector with large processing air volume, good dust cleaning effect, convenient dust removal, operation and maintenance, and small footprint.
Structure principle of bag filter in sand and gravel factory
The dust collector in the sand and gravel factory is a dust removal equipment composed of an upper box, a lower box, a middle box, and an ash hopper. When the pulse bag filter equipment is working normally, the dust containing gas enters the ash hopper through the air inlet. Due to the expansion of gas volume, some coarse dust particles fall into the ash hopper due to inertia or natural settling, while the rest of the dust particles rise into the bag chamber with the airflow. After being filtered by the filter bag, the dust particles are trapped on the outside of the filter bag. The purified gas enters the upper box through the inside of the filter bag and is then discharged into the atmosphere through the valve plate hole and exhaust outlet, thus achieving the purpose of dust removal.
Structure composition of stone crusher dust collector
1. Upper box: including dust collector cover, family transfer cover removal device, cleaning room, bag changing hole, observation hole, and purified air outlet.
2. Medium box body: including flower board, filter bag, filter bag frame, filter bag mouth, filter chamber cylinder, and dust containing gas inlet hole door.
3. The upper cover of this device is divided into multiple pieces, which can be opened freely, making bag replacement and maintenance very convenient
4. Lower box: including positioning support frame, ash hopper, star shaped ash discharge valve, and support.
5. Anti blowing dust cleaning mechanism: including a rotary arm nozzle anti blowing machine rotation reduction mechanism.
6. The bag dust collector in the gravel field adopts a high-pressure fan equipped with equipment to blow back and clean the dust, which is not limited by the gas source conditions of the application site, has fewer vulnerable parts, is easy to maintain and operate.
matters needing attention:
During the installation of the dust collector, pay attention to collisions and handle with care.
During the installation of the dust collector, asbestos rope is used in the middle between the box and the ash hopper flange, as well as the inlet and outlet flanges, and bolted tightly to prevent air leakage and affect the dust removal effect.
After being put into normal operation, it is necessary to discharge the ash on time, generally not exceeding 4 hours per time, to prevent excessive dust collection in the ash hopper. How to clean the dust collector of the crusher? 1. Metal shavings, broken cloth, crushed stones, and other foreign objects will be removed from the equipment.
Feixiang Company carries out environmental protection treatment from the source of pollution, adapting pollution control technologies for various complex working conditions to meet the different needs of the market.
