[0026] Firstly, the metal powder needing to be ground is poured into body 1 through inlet 101, then grinding roller 103 is driven to rotate in the middle part of grinding table 2 by the rotation of rotating shaft 102, and the metal powder slides into the gap between grinding roller 103 and sliding inclined plane 204, and is ground by the pressure of grinding roller 103 in the gap, so that the size of the particles is reduced to meet the use requirements.

[0027] The metal powder is ground, and slides along sliding inclined plane 204, and the gap between sliding inclined plane 204 and grinding roller 103 gradually reduces, so that only the powder with reduced size can continue to slide down, without causing part of the powder to slide down without being ground to the appropriate size, resulting in multiple grinding, and also preventing the grinding gap from being too small, so that larger particles cannot effectively and smoothly enter the grinding gap.

[0028] Further, the grading rods 202 are arranged in a circular ring on the surface of the sliding slope 204, and the grading rods 202 on the surface of the sliding slope 204 are arranged in several circular rings on the surface, the several circularly arranged grading rods 202 gradually decrease in diameter from top to bottom, the transmission assembly comprises a transmission rod 201, a limiting ring 2021, a transmission ring 203 and a transmission ring groove 2031, the transmission rod 201 is connected in the interior of the grinding table 2, the limiting ring 2021 is arranged on the side wall of the grading rod 202, the transmission ring 203 is arranged in the interior of the grinding table 2, the transmission ring groove 2031 is arranged on the inner wall of the middle part of the transmission ring 203, the transmission rod 201 is a circular rod which is drivingly connected to the motor in the interior of the grinding table 2, and one side of the transmission rod 201 is engaged with the tooth trace of the transmission ring 203, the transmission ring groove 2031 is matched with one end of the grading rod 202, and one side of the middle part of the transmission ring groove 2031 is provided with a rack which is engaged with one end of the grading rod 202, the limiting ring 2021 is a circular ring protrusion which is arranged on the side wall of the grading rod 202 and matched with the connecting cavity, and the transmission ring 203 is further provided with ball bearings on the upper and lower sides of the protrusion part, and the ball bearings on the two sides of the transmission ring 203 are matched with the circular ring grooves on the upper and lower sides of the inner wall of the connecting cavity.

The metal powder is ground, and the suitable metal powder will slide along the sliding slope 204, and the distance between the sliding slope 204 and the grinding roller 103 is gradually reduced, so that only the powder whose size is reduced by grinding can continue to slide down, and part of the powder will not be ground to the appropriate size and slide down, resulting in the need for multiple grinding. At the same time, it also prevents the grinding gap from being too small, so that larger particles cannot effectively and smoothly enter the grinding gap. At the same time, the suitable metal powder sliding along the sliding slope 204 will be further layered and graded by the grading rod 202. The arrangement of the grading rod 202 ring makes the sliding metal powder continue to slide only through the gap of the grading rod 202. The smaller the diameter of the grading rod 202, the smaller the gap, so that only the suitable metal powder that is gradually ground smaller can continue to slide down, ensuring that the powder of different grinding degrees is graded and ground, and the grinding is more comprehensive and there is no size difference.
