When the slag powder entering the grinding barrel 2 contains too much moisture, the temperature inside the grinding barrel 2 is raised by the hot air furnace 161, and the entry of cold air from the refrigerator is reduced.

[0025] A motor 24 is fixedly mounted on the barrel cover 21, and a rotating shaft 25 is fixedly mounted on the output end of the motor 24. A grinding roller 251, a grinding roller 252, and a grinding roller 3 253 are fixedly mounted on the rotating shaft 25 in sequence. The diameters of the grinding roller 251, the grinding roller 252, and the grinding roller 3 253 increase in sequence.

The output end of the hot air furnace 161 is fixedly connected to one end of the electric regulating valve 162, and the other end of the electric regulating valve 162 is fixedly connected to the air duct 163.
