Abstract

An three-separate selecting flour machine comprises the selecting powder room, vortex separator, upright transmission shaft, big fan, collection cone for meal, collection cone for fine flour, tray for strewing material, collection cone for middle meal, upright guiding fan, rotor. The collecting cone for middle meal is over the tray for strewing material, comprises the upper cone the lower cone. There has a path between the upper cone and the lower cone. The upright guiding fans are over the circumference of the lower cone. A rotor is over the two circumferences of the upper and the lower cones. A separating board is at the pole of the rotor. The rotor is installed below the upright transmission shaft and over the tray for straying material. The invention could screen fine flour, middle meal, meal from material unloaded from the grind.

Description

technical field [0001] The invention relates to a particle classification equipment in grinding operation, in particular to a three-separation powder separator used in cement production. Background technique [0002] At present, in the process of grinding, in order to reduce the phenomenon of over-grinding in the mill and improve the grinding efficiency, the materials in the mill must be unloaded in time, and the qualified products are selected by the classification equipment, and the unqualified coarse powder is returned to the mill for regrinding . In this process, the classification performance of the classifier will directly affect the output and power consumption of the mill. At present, the powder separators commonly used in the cement production process include cyclone powder separators and rotor powder separators. But there are only two kinds of materials selected by these two types of powder separators: one is qualified fine powder, and the other is unqualified co...
