The material smaller than the sieve hole can be directly fed into the reducing part without being crushed, while the material larger than the sieve hole is crushed by the crusher to the required particle size before entering the reducing part. The reducer selects the appropriate reducing ratio according to the needs of the user, reduces the material and enters the receiving part to complete a working cycle; When preparing samples of iron ore, it is necessary to first reduce the material and divide it into three parts, one for inspection, one for flushing and one for grinding. The inspection sample is a reserved sample, the flushing sample is used to remove the residue of the equipment, and the grinding sample is the raw material for formal sample preparation. In the process of processing the three samples, these samples need to be sent to the grinder, the reducer and the discharge port respectively.

The first mixer and reducer 201 is located inside the housing 100 and inside the feed port 107. The external material first enters the first mixer and reducer 201; The air compressor 202 is fixedly installed below the first mixer and reducer 201; The grinder 203 is located inside the housing 100. The grinder 203 is fixedly mounted on the bottom of the inner wall of the housing 100.

The second mixer and reducer 205 is connected to the undersize discharge port of the ultrasonic vibrating screen 204. The undersize refers to particles with a particle size smaller than the size of the screen hole, and the material that passes through the screen hole and falls below the screen surface during the screening process; The suction pump 206 is fixedly mounted on the bottom of the inner wall of the housing 100. The top of the suction pump 206 is connected to the screen oversize outlet of the ultrasonic vibrating screen 204 through a pipeline (not shown in the figure).

After receiving the signal, the motor starts to rotate and generate torque; Transmission mechanism: The rotational motion of the motor needs to be converted into linear motion through the transmission mechanism. In the three-axis module, common transmission mechanisms include lead screws and guide rails. The lead screw converts the rotational motion of the motor into linear motion, while the guide rail ensures the stability and accuracy of the module during the linear motion process.

The inspection sample is sent to the inspection sample taking port 104 for packaging through the three-axis module 209, and then the flushing sample is sent to the grinder 203, and after grinding, it is collected into the waste bucket 207 through the suction pump 206, and then formal grinding is carried out; During the formal grinding, the ground sample is sent to the grinder 203 through the three-axis module 209. After grinding, the material is sent to the ultrasonic vibrating screen 204 for screening through the three-axis module 209. The screened material is collected into the waste bucket 207 through the suction pump 206, and the screened material enters the second mixer and reducer 205. The material is evenly divided into three portions (each weighing about 66g), and sent to the ground sample feeding port 105 for packaging through the three-axis module 209, thereby completing the preparation of the sample.
