The flow control mechanism includes a rotary discharger 7, a motor assembly 8, a first inclined pipe 9, a first fixing plate 10, a flap valve 11, two second fixing plates 12, a control switch 13, and a second inclined pipe 15.

[0032] Furthermore, the rotary discharger 7 is fixedly connected to the lower side of the first discharge pipe 4, the motor assembly 8 is fixedly connected to the left side of the rotary discharger 7, and the motor assembly 8 can control the rotary discharger 7 to work.

Then, the coarse material will enter the interior of the first blanking pipe 4. The presence of the triangular body 6 can prevent the coarse material from remaining in the material box 1. The coarse material entering the interior of the first blanking pipe 4 will fall into the interior of the rotary discharger 7. Then, start the motor assembly 8. The motor assembly 8 drives the rotary discharger 7 to work. Then, the rotary discharger 7 will control the discharged material quantity through the rotation speed. Then, the coarse material will fall into the interior of the first inclined pipe 9 and finally enter the interior of the mill through the first inclined pipe 9.

[0036] Further, the coarse material that does not enter the first blanking pipe 4 will fall into the interior of the second blanking pipe 5.
