Dust Catcher

Features

Dust catcher also can be called dust collector,is a new type of the dust screening equipment, and its working principle is:

1. The powder gas is introduced from the mill gas outlet to the bottom of the classifier, the gas along the wind pipe rises to the upper exit, it is collected by the semolina on the collection cone (within the cone), diverging along the four directions to enter by the cone and shell body cavity and continuing to rise. When gas rose to the top, through the dust collector upper into it, and then materials meet the scattering material of trays, material is dispersed by the air flow, and first sorted (primary powder).

2. After the rougher powder, most of the particles with the gas is guided blade import vortex stars constituency, the rest of the coarse particles is decreased due to the effect of gravity to the spout. particles into the eddy current separation is driven by the whirling airflow generated by the high speed rotation of the turbine blades, is further dispersed and obtained a certain degree of centrifugal force, while the particles may also be the role of the gas drag force, the centrifugal force is less than the gas drag force, the particles within the eddy zone of the turbine blade, then into the cyclone, finished products fell into the set of dust-collecting box.

3. If the centrifugal force of the particles is greater than the gas drag force, the particles are re-taken to the dispersing zone, the collection cone, and due to the action of gravity down landing to coarse particles and the particles fall into the cone bottom, and it is scoured by the bottom air, making the fine powder separate from the surface of the particles with the air into the eddy zone, and into the cyclone collection. Coarse particles divide three columns from the inner cone, inflowing the lower discharge port of the selected powder machine, and again into the mill.
