[0021] Working principle: In the process of grinding the raw materials of low-temperature co-fired ceramic dielectric materials, the existing powder-forming device cannot grade and grind the raw materials, resulting in a low powder-forming efficiency of the device. By pouring the raw materials from the second feed hopper 12 into the grinding box 11, the second motor 14 is operated to drive one of the grinding rollers 13 to rotate, and the grinding roller 13 drives the first gear 15 on it to rotate, the first gear 15 drives the second gear 16 to rotate, and the second gear 16 drives the other grinding roller 13 to rotate, that is, the two grinding rollers 13 move relatively synchronously, and the two grinding rollers 13 The raw materials are crushed, and then the crushed raw materials fall onto the screen plate 17.

When the raw materials are powdery, they will be discharged from the rotating plate 7. The sieve holes fall downward and are then discharged from the first discharge hopper 5, realizing rapid powder processing of the raw materials. This structure performs graded crushing and grinding on the raw materials. Small-particle raw materials are powdered faster during the grinding process, which is beneficial to improving the powdering efficiency. The existing powdering device cannot repeatedly crush large-particle raw materials during the grinding process of low-temperature co-fired ceramic dielectric materials. Large-particle raw materials are prone to cause blockage inside the device, resulting in poor production continuity of the device. The crushed raw materials fall onto the sieve plate 17, and the small-particle raw materials fall from the sieve holes of the sieve plate 17 to the guide plate 1 8, and then poured into the first feed hopper 4 from the third discharge hopper 20, and the large-particle raw material is poured into the feed pipe 22 from the second discharge hopper 19, and then enters the guide cylinder 21, and is operated by the third motor 25 to drive the rotating rod 26 to rotate, and the rotating rod 26 drives the spiral blade 27 to rotate, and the spiral blade 27 pushes the large-particle raw material to move upward, and then the large-particle raw material is poured into the grinding box 3 again from the discharge pipe 23, and is crushed again.
