[0035] Grinding stage: The operator turns on the switch knob 16 of the belt grinder 1, the belt grinder 1 starts, the belt 15 or the sanding disc 14 rotates at high speed. Then, the operator holds the rod-shaped sample 24 and flexibly selects the belt 15 or the sanding disc 14 for grinding according to the oxide scale condition of the sample surface. During the grinding process, the rod-shaped sample 24 is moved at a uniform speed to ensure that the oxide scale is completely removed. After the grinding is completed, the belt grinder 1 is turned off.

[0036] Front-end shearing stage: The polished rod-shaped sample 24 is placed on the left shearing position 17 of the dedicated shearing device 2; the left shearing position 17 is set on the fixed die holder 11 and is designed specifically for shearing the front end of the rod-shaped sample 24; then, the operator presses the start button 6 on the workbench, and after receiving the instruction, the electrical control box 9 immediately controls the hydraulic workstation 8 to start; the hydraulic workstation 8 drives the hydraulic cylinder 7 to push the cylinder base 26 downward, and the cylinder base 26 drives the connecting rod 25 to pull the movable die holder 12 downward synchronously, cooperating with the fixed die holder 11 to cut off the front end of the rod-shaped sample 24; after the front end of the sample is cut off, the electrical control box 9 controls the hydraulic system to switch the hydraulic control valve, and the hydraulic cylinder 7 drives the movable die holder 12 to move upward from the lower position and return to the initial position;

[0037] Particle shearing and collection stage: Move the rod-shaped sample 24 to the right shearing position 18. According to the testing requirements, rotate the limiting screw 20 to adjust its position and limit the extension length of the rod-shaped sample 24, taking a sample particle with a length of 3mm as an example; press the start button 6 again to repeat the above shearing action and cut off the sample particle that meets the length requirement; when the movable die holder 12 shears downward, the inclined guide block 21 pushes out the limiting screw fixing seat 19, causing the sheared sample particle to lose support and fall off by itself; the sample particle slides down along the sample guide groove 22 and falls into the corresponding sample collection box 23 on the base 10; the operator takes out the sample collection box 23 to collect the sheared sample particle for subsequent component analysis and testing.
