The return trough 172 is connected to the interior of the first crushing cylinder 1. Through the arrangement of the rotating rod 144, the sleeve rod 145, the movable plate 146, the screen 147, the collecting box 41, the side trough 42, the valve B43, the motor B45, the top trough 46, the connecting short plate 16, the inclined top frame 17 and the return trough 172, after the crushing roller 13 performs preliminary crushing, the movable plate 146 cooperates with the screen 147 to screen the crushed raw materials, and the larger particles of raw materials are screened out and flow along the movable plate 146 rolls toward the discharge port, at which time valve B43 is opened, and the raw material particles enter the collecting box 41 from the side groove 42. After the collection is completed, valve B43 is closed and motor B45 is turned on. Motor B45 drives shaft B to rotate and then drives collecting box 41 to rotate, so that the collected raw material particles are poured out from the top groove 46 and poured from the return groove 172 into the first crushing cylinder 1 for re-crushing. The inclined setting of the inclined top frame 17 can facilitate the pouring of raw material particles from the return groove 172.
[0027] A motor A141 is fixedly connected to one side of the first crushing cylinder 1, and a rotating shaft A142 is fixedly connected to the output end of the motor A141. An eccentric roller 143 is fixedly connected to the outer side of the rotating shaft A142. The eccentric roller 143 is fitted with the bottom surface of the movable plate 146. Through the arrangement of the motor A141, the rotating shaft A142 and the eccentric roller 143, when the raw material particles are screened, the motor A141 is turned on, and the motor A141 drives the rotating shaft A142 to rotate, and then drives the eccentric roller 143 to rotate, thereby continuously striking the bottom surface of the movable plate 146, and the sleeve rod 145 rotates around the rotating rod 144, which prevents the screen 147 from being blocked while promoting larger particles to roll down along the movable plate 146.
[0028] An inclined plate 44 is fixedly connected to the inner wall of the collecting box 41. Through the arrangement of the inclined plate 44, the raw material particles are discharged along the inclined plate 44 for easy dumping.
[0029] A valve A15 is fixedly connected to the bottom surface of the inner wall of the first pulverizing cylinder 1. The fine pulverizing mechanism 5 includes a motor C51 fixedly connected to the inner wall of the base 3. The output end of the motor C51 is fixedly connected to a rotating shaft C52. The rotating shaft C52 penetrates the bottom surface of the second pulverizing cylinder 2 and is rotatably connected to the second pulverizing cylinder 2. A grinding roller 53 is fixedly connected to the outer side of the rotating shaft C52. A convex block 54 is fixedly connected to the outer side of the grinding roller 53. Through the arrangement of the valve A15, the motor C51, the rotating shaft C52, the grinding roller 53 and the convex block 54, after the pulverizing roller 13 finishes pulverizing, the valve A15 is opened to allow the raw material particles to fall into the second pulverizing cylinder 2. At the same time, the motor C51 is turned on. The motor C51 drives the rotating shaft C52 to rotate, and then drives the grinding roller 53 and the convex block 54 to rotate, so as to further pulverize the raw material particles. When the pulverizing speed inside the first pulverizing cylinder 1 is too fast, the valve A15 can be closed to slow down the feeding speed of the raw material particles, thereby ensuring the pulverizing effect of the fine pulverizing mechanism 5.
[0030] A protective ring 531 is fixedly connected to the bottom surface of the grinding roller 53, and an annular groove 22 is provided on the inner wall of the second crushing cylinder 2. The protective ring 531 is clamped in the annular groove 22. The setting of the protective ring 531 and the annular groove 22 can protect the rotating shaft C52, thereby ensuring that the crushed raw materials can be discharged smoothly.
[0031] The inner wall of the return chute 172 is slidably connected with a partition door 171. Through the arrangement of the partition door 171, the partition door 171 is closed when the crushing roller 13 is working to prevent the crushed materials from splashing and injuring people.
[0032] A feed pipe 11 is fixedly connected to one side of the first crushing cylinder 1, a dumping plate 12 is fixedly connected to the inner wall of the first crushing cylinder 1, the feed pipe 11 and the dumping plate 12 are arranged correspondingly, and a discharge pipe 21 is fixedly connected to the outer side of the second crushing cylinder 2. The setting of the feed pipe 11, the dumping plate 12 and the discharge pipe 21 facilitates the feeding and discharging of raw materials.
[0033] Specifically, after the initial crushing, the crushed raw materials are screened by using the movable plate 146 in conjunction with the screen 147, and the motor A141 is turned on at the same time. The motor A141 drives the rotating shaft A142 to rotate, and drives the eccentric roller 143 to rotate. The eccentric roller 143 continuously knocks on the bottom surface of the movable plate 146, and the sleeve rod 145 rotates around the rotating rod 144, thereby driving the movable plate 146 to vibrate continuously, preventing the screen 147 from being blocked while promoting larger particles to roll down along the movable plate 146. At this time, the valve B43 is opened, and the raw material particles enter the collection box 41 from the side groove 42. After the collection is completed, the valve B43 is closed and the motor B45 is turned on at the same time. The motor B45 drives the rotating shaft B to rotate and then drives the collection box 41 to rotate, and the collected raw material particles are poured out from the top groove 46 and poured from the return trough 172 into the first crushing tube 1 for re-crushing, thereby finally achieving the purpose of collecting and re-crushing larger particles of ore.
