At the bottom end inside the crushing plate 9, filtering holes 13 are evenly arranged. Above the crushing plate 9 and inside the processing box 1, a rotating roller 11 is rotatably connected. At the four ends on the outer side of the rotating roller 11, ring hammers 10 are rotatably connected. At the bottom end of the crushing plate 9, a funnel 14 is fixed. At the top end and the bottom end inside the funnel 14, a large roller 16 and a small roller 17 are rotatably connected respectively. At the bottom end of the crushing plate 9, a collecting hopper 7 is fixed;

[0031] When it is necessary to pour the spheroidizing agent into the crusher for processing, at this time, rotate the rotating roller 11 to drive the ring hammers 10 to rotate, so that the ring hammers 10 crush the spheroidizing agent. The spheroidizing agent hammered into small pieces falls into the inside of the funnel 14 along the filtering holes 13. Then, start the large roller 16 and the small roller 17 to rotate, so that the spheroidizing agent is gradually crushed step by step from top to bottom in the crusher;

[0032] By crushing with the ring hammers 10 and crushing with the large roller 16 and the small roller 17, the required particle size requirements can be achieved, greatly improving the crushing efficiency of the equipment. The overall structure of the crusher is simple, the degree of automation is high, the feeding and discharging are convenient and easy, and the workload of personnel is reduced;

[0033] Adopting the step-by-step crushing method, the spheroidizing agent is gradually crushed from large to small to a suitable particle size, effectively reducing the wear of the equipment and increasing the service life of the equipment;

[0034] Adopting a closed structure, with low noise, at the same time reducing dust pollution and the treatment cost of the enterprise. Thus, it can be seen that this kind of crusher has very wide practical value;

[0035] On one side of the processing box 1, a protective box 4 is fixed. Inside the protective box 4, a transmission mechanism is arranged. The transmission mechanism includes meshing gears 6. On one side of the large roller 16, it passes through the processing box 1 and is fixed with a meshing gear 6. Between the two meshing gears 6, they are meshed and connected. On the other side of the processing box 1, a servo motor 5 is fixed. The output end of the servo motor 5 is fixed to one of the large rollers 16;

[0036] Through the output end of the servo motor 5 driving one of the large rollers 16 to rotate, so that one of the large rollers 16 drives one of the screening holes 18 to rotate synchronously with the other large roller 16 and screening hole 18, facilitating the synchronous rotation of the two large rollers 16;

[0037] Between the meshing gears 6 at the same end and the small roller 17, they are rotationally connected through a transmission belt;

[0038] The screening hole 18 drives the small roller 17 to rotate synchronously through the transmission belt;

[0039] Inside the collecting hopper 7, a conveying slurry 15 is rotatably connected. At one end inside the collecting hopper 7, a driving motor 12 is fixed, and the output end of the driving motor 12 is fixed to the conveying slurry 15;

[0040] By starting the driving motor 12 to drive the conveying slurry 15 to rotate, it is convenient to orderly discharge the crushed spheroidizing agent;

[0041] On the other side of one of the large rollers 16, it is rotatably connected to the roller 11 through a transmission belt. When the large roller 16 rotates, the roller 11 and the ring hammers 10 are effectively driven to rotate through the transmission belt, which is convenient for initially crushing the spheroidizing agent and dropping the crushed spheroidizing agent between the large roller 16 and the small roller 17 for further crushing;

[0042] At one end inside the crushing plate 9, a screening hole 18 is opened. Inside the screening hole 18, a material guiding port 19 is fixed, and the outside of the material guiding port 19 is fixed to the processing box 1;

[0044] When encountering hard spheroidizing agents that are not easily crushed by the ring hammers 10, at this time, the hard spheroidizing agents can be driven by the rotation of the roller 11 to be transported into the screening hole 18 and the material guiding port 19 and fall into the collecting box 2, so they are crushed manually;

[0045] At the top of the processing box 1, a feeding port 8 is fixed, which is convenient for pouring the spheroidizing agent into the processing box 1.

[0046] The usage process of a kind of step-by-step crusher for spheroidizing agent provided by the present utility model is as follows: When it is necessary to pour the spheroidizing agent into the crusher for processing, at this time, start the servo motor 5 to drive the two large rollers 16 to rotate synchronously. The large roller 16 and the small roller 17 rotate synchronously through the transmission belt, and one of the large rollers 16 and the roller 11 rotate synchronously through the transmission belt. Then the roller 11 and the ring hammers 10 initially crush the spheroidizing agent, and the crushed spheroidizing agent falls from the inside of the filtering hole 13 between the large roller 16 and the small roller 17 for further crushing, so that the spheroidizing agent is gradually crushed step by step from top to bottom in the crusher, effectively crushing the spheroidizing agent from large to small to a suitable particle size;

[0047] Then the spheroidizing agent with a suitable particle size is orderly discharged through the conveying slurry 15. When the spheroidizing agent that is not easily crushed by the ring hammers 10, it will fall into the collecting box 2 along the screening hole 18 and the material guiding port 19 due to the rotation direction of the ring hammers 10, so it is crushed manually and then put into the crusher again.
