[0024] When the staff needs to use the powder selecting machine to select cement powder, the cement powder can be added in the shell 11 through the screening mechanism 2, and the cement powder will fall on the grinding sieve plate 17. Some powdered cement powder will seep through the pores of the grinding sieve plate 17 to the bottom of the shell 11, and some cement powder lumps will be retained on the grinding sieve plate 17. The staff can start the permanent magnet motor body 12 to drive the rotating rod 13 to rotate, so that the grinding paddle 15 will rotate in a circle to grind the cement powder lumps on the grinding sieve plate 17. At the same time, some cement powder may be blocked in the pores of the grinding sieve plate 17, and the impact part 16 of the grinding paddle 15 will collide with the protrusion 18 when rotating, thereby generating some vibration force to make the cement powder blocked in the pores of the grinding sieve plate 17 vibrate and fall off, ensuring the permeability of the grinding sieve plate 17 and the powder selecting efficiency of the cement grinding powder selecting machine. After some cement powder falls through the grinding sieve plate 17, it may adhere to the inner wall of the shell 11.
