Application scope of dry mist dust suppression in coal preparation plant
Unloading machines, dump trucks, train unloading ports, truck unloading ports, car receiving troughs, vibrating feeders, impeller coal feeders, belt coal feeders, circular silos, strip silos, belt stackers, stackers, reclaimers, belt transfer towers, coal crusher rooms, fine crusher rooms, coal plow rooms, truck slag outlets, ash storage, belt head chutes, double-layer resonant screens, sieve outlet coal hoppers, impact crushers, crusher drop pipes, screen drop pipes, inclined drop pipes, etc. all generate a large amount of dust, seriously polluting the working environment on site and causing coal material loss. There is a large amount of coal dust covering the workshop floor, which requires a large amount of cleaning by staff every day.



Dust sources and reasons for dust generation
⑴Belt head chute, where materials leave the conveyor belt for transportation3m/s5m/sThe initial velocity of the material moves downwards, creating a negative pressure zone during the movement. Small particles of material are lifted up by the airflow, producing dust. When the material comes into contact with the feeding tube, it collides and overflows, producing dust. During the collision of the material with the feeding tube, a strong airflow is generated, and small particles of material are lifted up by the airflow, producing dust.
