[0027] like Figure 1 and Figure 3 As shown, it also includes a water tank 14, a water pipe 15 and a nozzle 16. The water tank 14 is connected to the middle of the bottom of the grinding box 1 by bolts. The bottom of the grinding box 1 and the top of the water tank 14 are both provided with collecting ports. The rear side of the top of the water tank 14 is connected with a water pipe 15. The water pipe 15 runs through the rear side of the grinding box 1. A water pump is connected to the water tank 14. The lower end of the water pipe 15 is connected to the water outlet end of the water pump. Two nozzles 16 are connected to the upper front side of the water pipe 15.

[0030] like Figure 1 As shown, a collecting box 19 is also included. The collecting box 19 is used to collect the cylindrical magnetic materials that have been ground. The collecting box 19 is located below the conveying wheel 7.

[0031] like Figure 1 As shown, it also includes a fixing block 20 and a clamping screw 21.

The water in the water tank 14 is sprayed out from the nozzle 16 through the water pipe 15 and sprayed onto the cylindrical magnetic material to cool the cylindrical magnetic material to prevent the cylindrical magnetic material from being worn due to excessive temperature. The dirty water falls into the water tank 14 through the collection port, and the ground cylindrical magnetic material will fall into the collection box 19 to facilitate subsequent collection. The clamping screw 21 clamps the collection box 19 to prevent the collection box 19 from shifting. Loosening the clamping screw 21 can loosen the collection box 19.
