Problems solved by technology
The fine powder produced continuously during the crushing process will continue to participate in the crushing process, causing regrinding and over-grinding of the fine powder, and the fine powder will seriously hinder the continued crushing of coarse materials, greatly reducing the grinding efficiency
In addition, due to the clumping among the particles of the powder to be classified, the adhesion is serious, especially the tiny particles are more serious, which seriously affects the classification operation.

Embodiment Construction
[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.
[0019] like figure 1 As shown, a micropowder classifier includes a mounting bracket 1, a primary separator 2 and a secondary separator 3 are mounted on the mounting bracket 1, and the primary separator 2 and the secondary separator 3 are connected by an elbow 4, One end of the elbow 4 is connected to the upper end of the primary separator 2, and the other end is connected to the feed port of the secondary separator 3. The design of the elbow 4 further improves the classification effect of the micropowder material, and the elbow 4 is also connected with a vibration excitation The design of the exciter 5 and the vibration exciter 5 can further classify the fi...

The invention relates to the field of micro powder equipment, in particular to a micro powder grading machine. The micro powder grading machine comprises a mounting support. A first-grade separator and a second-grade separator are mounted on the mounting support and connected through a bending pipe. One end of the bending pipe is connected with the upper end of the first-grade separator, and the other end of the bending pipe is connected with a feeding opening of the second-grade separator. A vibration exciter is further connected to the bending pipe. A first-grade feeding opening is formed in the top end of the first-grade separator, and a first-grade discharging opening is formed in the bottom of the first-grade separator. A second-grade discharging opening is formed in the bottom of the second-grade separator. The top end of the second-grade separator is further connected with a micro powder collector. The bottom of the first-grade separator and the bottom of the second-grade separator are each connected with an air blower. The air blowers are connected with air speed adjusting devices. The micro powder grading machine is simple in structure, reasonable in design and high in micro powder material grading precision, and the grading efficiency of micro powder materials is greatly improved by means of design of S-shaped annular protrusions.
Description
technical field [0001] The invention relates to the field of micropowder equipment, in particular to a micropowder classifier. Background technique [0002] At present, the use of ball mill to crush material micropowder and classification are two operation processes. Generally, the material to be crushed is filled into the ball mill and sealed, crushed to the required fineness and taken out together, and then the crushed material is placed in the classification machine for classification. In the process of pulverization, the continuously generated micropowder will continue to participate in the pulverization process, causing the regrinding and overgrinding of the micropowder, and the micropowder will seriously hinder the continued pulverization of the coarse material, greatly reducing the grinding efficiency. In addition, due to the agglomeration between the particles of the powder to be classified, the adhesion is serious, especially the tiny particles are more serious, wh...
