[0002] In the mineral processing operation, whether in scientific research or production experiment, the original sample needs to be crushed and divided into single samples before the research. The preparation of these samples not only meets the requirements of test work on test granularity and weight, but also represents the whole original sample in terms of material composition and physical and chemical properties. The conventional sample separation method for mineral processing test is generally using the heap cone ring cutting method for large amount of ore, and using the halving method or point taking method for small amount of ore.

[0003] The previous sample separation method is manual operation, which has complex sample separation procedure, and the crushed minerals are scattered in different places, causing pollution of the working space. In addition, the irregular flying of the minerals during the crushing process can cause harm to the operator. Moreover, the content and uniformity of the mineral material are not easy to control, which brings many inconveniences to the actual experimental requirements and actual operation, and affects the experimental effect and efficiency.

[0004] Therefore, the patent CN 219121829 U discloses a mineral sample automatic crushing, mixing and sample separation device, which comprises a crushing device, a mixing device and a sample separation device. The crushing device comprises a crushing bin A and a crushing bin B, and the bottom of each crushing bin is fixedly connected with a support. A crushing motor A and a crushing motor B are installed on the side of the bottom of each crushing bin, respectively. An A sample outlet and a B sample outlet are formed on the side close to each crushing motor, and a transmission wheel A and a transmission wheel B are arranged at the bottom center of each outlet. An A transmission belt and a B transmission belt are connected with the outside of each transmission wheel. The mixing device comprises a mixing motor, and the output end of the mixing motor is connected with a mixing stirrer. The mineral sample automatic crushing, mixing and sample separation device can easily control the uniformity of the mineral sample, which brings many conveniences to the actual experimental requirements and actual operation, and greatly improves the experimental effect and efficiency.

[0005] Although the above structure can solve the drawbacks of manual operation, it occupies a large space, and the crushing bin adopts a simple structure. The crushing head at the output end of the motor crushes the ore, which has low crushing efficiency, resulting in long crushing time and affecting the sample separation efficiency. It cannot meet the requirements of high precision and high efficiency sampling. UTILITY MODEL CONTENTS
