The improved device of this embodiment is that a plurality of partition plates 2 are fixedly connected to the inner wall of the coarse powder hopper 1, and the plurality of partition plates 2 divide the coarse powder hopper 1 into a plurality of compartments 3, and a compartment 3 is provided between two adjacent partition plates 2.
[0019] The partition plate 2 is made of steel plate, and the partition plate 2 is intermittently welded and fixed to the inner wall of the coarse powder funnel 1. There are 8 compartments 3.

[0020] The grinding body of the vertical mill is located below the lower shell 9 of the powder classifier. The material is fed into the grinding disc in the grinding body, and a material layer of a certain thickness is formed on the grinding disc. The grinding roller is pressurized to generate pressure, and the material is ground into a certain fineness. The grinding disc is rotating, and the material is scattered. There is a certain negative pressure wind inside the grinding body, and the material is sucked away by the wind and taken away from the grinding disc. The sucked away material passes through the powder classifier above the vertical mill. The fine particle material that meets the production requirements is taken out of the fine powder outlet of the upper shell 6 of the powder classifier by the negative pressure wind of a certain pressure to form a finished product; the coarse particle material that cannot be taken away by the negative pressure wind of a certain pressure falls into the coarse powder funnel 1 (see Figure 1 The flow direction of the coarse particle material in the coarse powder hopper is the downward arrow), and the coarse particle material is discharged through the discharge port 5 at the bottom of the coarse powder hopper 1.

The partition plate 2 is a steel plate of a certain height and length. The coarse powder funnel 1 is divided into 8 compartments with a steel plate. The production cost is not high, and it is fixed by intermittent welding and easy to replace. Intermittent plates 4 are staggered and fixed on the inner wall of each compartment 3. The length of the intermittent plates 4 extends from top to bottom. The intermittent plates 4 also have a certain breaking up effect on the small material agglomerates located in the compartment 3, further reducing the probability of clogging the discharge port 5 at the bottom of the coarse powder funnel 1.
