In the embodiment, a negative pressure environment is formed through the induced air mechanism 6, and dust at the feed inlet 101 and the discharge outlet 102 of the aggregate bin 1 is sequentially introduced into the gravity dust removing mechanism 3, the cyclone dust removing mechanism 4 and the cloth bag dust removing mechanism 5. And the gravity dust removing mechanism 3, the cyclone dust removing mechanism 4 and the cloth bag dust removing mechanism 5 form a multistage dust removing system together for dust removing treatment.

The gravity dust removing mechanism 3 utilizes the density difference of dust and gas to enable the dust to naturally sink from the airflow by the gravity of the gravity dust removing mechanism, thereby achieving the purpose of separating or capturing particles in the dust-containing airflow and being suitable for large-particle dust treatment; the cyclone dust removing mechanism 4 is used for enabling dust-containing airflow to rotate, separating dust particles from the airflow by virtue of centrifugal force and collecting the dust particles on the wall of the airflow, and settling and collecting the dust particles by virtue of gravity, so that the cyclone dust removing mechanism is suitable for general dust treatment; the bag-type dust removing mechanism 5 is a dust removing device which uses a bag-type filter element made of fiber fabric to collect solid particles in dust-containing gas, and the action principle of the dust removing device is that dust particles are intercepted due to collision between inertial force and fibers when bypassing filter cloth fibers, so that the dust removing device is suitable for removing fine dust.

In summary, the multistage dust removal system formed by the gravity dust removal mechanism 3, the cyclone dust removal mechanism 4 and the cloth bag dust removal mechanism 5 can efficiently and thoroughly remove dust generated by ore aggregate.
