Mill barrel structure

The invention discloses a mill barrel structure. The mill barrel structure comprises a feeding end cap, a barrel, a grate, a partition and a discharging end cap, wherein the feeding end cap and the discharging end cap are separately arranged at two ends of the barrel; the partition is welded to the inside of the barrel so that the inside of the barrel is divided into a grinding bin and a finishedproduct bin; a feeding end lining plate is mounted on the inner side of the feed end cap; a discharging end lining plate is mounted on the inner side of the discharging end cap; the grate is mounted on the partition; a barrel lining plate is arranged on the inner wall of the barrel; a grinding medium is added in a grinding bin of the barrel. The partition is welded to the inside of the barrel, materials are forced to be discharged by a mode of mounting the discharging grate, material grinding time is shortened, the material does not need to be taken out from the barrel by wind, thus, the windquantity does not need to
