[0030] Specifically, during the silicon powder mixing process, the motor 8 is first started. After the sliced ​​silicon mud as the raw material is put into the feed basket 1, the rotating rod 9 driven by the motor 8 will rotate. The rotating rotating rod 9 transmits the transmission to the bottom pulley 10 connected to the other end thereof. The bottom pulley 10 is driven by the belt drive and the top pulley 10 connected to one of the crushing rollers 2 is rotated, so that the crushing roller 2 rotates and drives the gear 3 connected thereto to rotate, and the gear 3 meshes with another gear 3 to transmit the two gears 3, so that the two gears 3 together with the crushing rollers 2 connected thereto rotate inwardly toward each other, so that the silicon mud in the feed basket 1 is sucked between the two crushing rollers 2 for crushing, and falls into the mixing drum 4 from the bottom side of the two crushing rollers 2. When the rotating rod 9 rotates, it also drives the bevel gear 7 fixed on the outer wall to rotate, and drives the bevel gear 7 connected to the stirring shaft 6 to rotate, so that the stirring shaft 6 drives the stirring roller on the outer wall to rotate inside the mixing drum 4 to stir the raw materials in the drum. By using the method of crushing first and then stirring, the efficiency of the stirring pre-processing before granulation is greatly improved, and the stirring accuracy is further improved, reducing the generation of large particles, so that the subsequent granulation process can proceed stably.

When passing through the material guide channel 11, the magnetic separator 15 will absorb the iron in the silicon mud, thereby improving the purity of silicon. Through the rotation of the motor 2 13, the auger 14 located in the feeding barrel 12 rotates, so that the raw materials entering the feeding barrel 12 are transmitted by the auger 14 and sent to a high place, and enter the granulator body 17 along the output end of the feeding barrel 12 to carry out the granulation process.

[0033] Reference Figure 1 A granulator body 17 is used for granulating silicon powder. The feed port of the granulator body 17 is located at the bottom side of the output end of the upper barrel 12.

[0034] Working principle: Before the silicon powder mixing process is carried out, firstly, the sliced ​​silicon mud as the raw material is put into the feed basket 1, and then the motor 8 is started. After the rotating rod 9 is driven by the motor 8, the rotating rotating rod 9 drives the pulley 10 at the bottom end connected to the other end thereof, and the pulley 10 at the bottom end is driven by the belt to rotate the pulley 10 at the top end connected to one of the crushing rollers 2, so that when the crushing roller 2 rotates, the gear 3 connected thereto is driven to rotate, and the gear 3 is meshed with another gear 3 to drive the two gears 3 together with the crushing roller 2 connected thereto to rotate inwardly in opposite directions, so that the silicon mud in the feed basket 1 is sucked between the two crushing rollers 2 for crushing, and falls into the mixing drum 4 from the bottom side of the two crushing rollers 2. When the rotating rod 9 rotates, it will also drive the bevel gear 7 fixed on the outer wall to rotate, and the bevel gear 7 connected to the stirring shaft 6 will be driven to rotate, so that the stirring shaft 6 drives the stirring roller on the outer wall to rotate inside the mixing drum 4, stirring the raw materials in the drum, and the raw materials that have been stirred will enter the upper barrel 12 along the material guide channel 11 through the discharge port on the bottom side of the mixing drum 4. When passing through the material guide channel 11, the magnetic separator 15 will absorb the iron in the silicon mud, and through the rotation of the motor 13, the auger 14 located in the upper barrel 12 will rotate, so that the raw materials entering the upper barrel 12 are transmitted by the auger 14, sent to a high place, and enter the granulator body 17 along the output end of the upper barrel 12 for granulation process.
