[0030] Example 1, see Figure 1-3 :

[0031] A device for conveying a mineral processing agent medium comprises a bag separator 1, an elevator 2, a cross-platform conveyor 3, a screw conveyor 4 and a plurality of mixing barrels 5. The bag separator 1 is used for cutting the bag of the mineral processing agent medium. The mineral processing agent medium is conveyed to the screw conveyor 4 after passing through the elevator 2 and the cross-platform conveyor 3. The screw conveyor 4 conveys the mineral processing agent medium to the corresponding mixing barrels 5.

[0032] The bag separator 1 and the elevator 2 are arranged in the reagent plant area, the mixing barrel 5 is arranged in the flotation plant area, and the bag separator 1 is arranged in the reagent plant area where the reagent is stored, which is conducive to ensuring the storage and bag breaking safety of the mineral processing reagent medium. The cross-platform conveyor 3 is set up between the reagent plant area and the flotation plant area to avoid affecting the normal passage of people and vehicles between the reagent plant area and the flotation plant area. Specifically, the cross-platform is installed on the platform connecting frame.

[0033] The top opening 11 of the bag separator 1 is provided with a bag cutting blade for cutting the mineral processing agent medium bag, and a material bin 12 is provided in the top opening 11, and the bottom of the material bin 12 is connected to the bag material outlet.
