Description

Grading device with angle for vertical grading wheel blade
Technical Field
The invention relates to a grading device for grading powder materials, in particular to a grading device with an angle on a vertical grading wheel blade.
Background
For materials which are crushed, especially for materials which are subjected to superfine crushing, powder with the size of less than several microns required in the mixed materials is separated, and the common screening method is difficult. Therefore, a classification technique is required to separate the desired materials, and thus a classification apparatus is required.
The grading method of the superfine powder is very goodThere are two types of classification, wet classification and dry classification. For dry separation, the coarser particles are usually separated by cyclone separation. The method is characterized in that powder moves under the action of induced air force, when the powder enters a cyclone separator, thicker powder falls into a collecting barrel below the cyclone separator along with downward rotary force due to the gravity of the powder, and thinner materials are discharged from an air outlet above the cyclone separator along with air flow and enter a dust remover to realize gas-solid separation. However, the method is used for mixing the air flow (50-600 g/m) of the fine powder and the powder with high concentration3) The method is not suitable because a part of the fine powder runs away along with the airflow without being captured, and meanwhile, the influence factors of cyclone separation are too many, and the classification precision is not high, so that how to effectively and accurately separate the required material particles becomes the key for solving the problem.
