Background
The powder concentrator is widely applied to grinding and pulverizing production lines of mineral materials such as metallurgy, building materials, chemical industry, mines and the like, and is matched with a Raymond mill, a vertical roller mill and other mills to obtain powder with particles with required fineness after the powder is ground by the mill and the powder is separated by the powder concentrator. The structure that currently generally adopts is fixed powder concentrator impeller on the center pin, and current structure air current only needs to be through the route of buckling after the powder concentrator impeller can flow out the powder concentrator, and the powder concentrator that has center pin drive that current adopted has two kinds of common structures: one is a flat disc impeller rotor, the center is given off air, and the structural air flow can flow out after passing through the rotor and being bent for two times by approximately 90 degrees; the other is that the bypass of the cage-shaped rotor is discharged, and the airflow with the structure is concentrated to one side of the air outlet hole after passing through the rotor and then flows out of the powder concentrator after passing through a bending route with a certain angle. The current structure causes the airflow path to be bent much, the kinetic energy loss is large, and the energy consumption is increased. In addition, the central shaft is usually driven to rotate by an external motor, so that the powder selecting machine can be suitable for selecting powder with different fineness particles, and a speed reducer is required to be arranged, so that the transmission stage number is increased, the energy utilization rate is reduced, and meanwhile, the powder selecting machine is complex in structure and high in cost.
