Description

Technical Field

[0001] The utility model relates to the technical field of magnetite powder classifiers, in particular to a high-efficiency magnetite powder classifier. Background Art

[0002] As we all know, magnetite is a high-quality raw material for iron-making. Steel mills have strict technical requirements on the grade, particle size distribution, and impurity content such as silicon dioxide, phosphorus and sulfur of iron concentrate during sintering, pelletizing and iron-making.

[0003] A Chinese patent document discloses (authorization announcement number CN218360649U), a high-efficiency magnetite powder classifier. The device cooperates with the first sieve plate, the second sieve plate and the third sieve plate. The operator can start the motor, and the motor drives the belts on the left and right wheels to rotate. The right wheel drives the rotating rod to rotate, and the rotating rod drives the cam to rotate. The cam rotates, so that the cam drives the first sieve plate to move up and down, and when the cam moves up and down, the bottom of the cam will contact the second sieve plate. The first sieve plate and the second sieve plate continue to screen the magnetite powder. After the screening is completed, the smaller magnetite powder falls from the second sieve plate to the top of the third sieve plate. Since the sieve hole of the third sieve plate is small, the impurities in the magnetite powder can be separated, and the remaining magnetite powder falls to the bottom of the shell, so that the magnetite powder can be screened in multiple stages.

[0004] A feeding hopper is fixed on the top of the shell in the device. The feeding hopper is funnel-shaped. Magnetite powder enters the feeding hopper and accumulates in the middle of the first sieve plate. Both the first sieve plate and the second sieve plate are driven up and down by cams. The magnetite separation time is relatively long. Therefore, we have designed a high-efficiency magnetite powder classifier to further optimize the above device. Utility Model Content

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides a high-efficiency magnetite powder classifier, which has the following beneficial effects:

[0016] The high-efficiency magnetite powder classifier drives the rotating rod to rotate through a motor, and the sliding rod is Z-shaped, which can make the first screen plate and the second screen plate swing back and forth. The mesh number of the first screen plate is smaller than that of the second screen plate, which is convenient for distinguishing the magnetite powder.
