Description

Technical Field

[0001] The utility model relates to the field of tube mills, in particular to an anti-blocking grate plate for a tube mill. Background Art

[0002] The original anti-blocking grate plate was a screen that was tightened with bolts when installed against the casting at the bolt hole. However, during use, the screen was continuously impacted by the steel balls in the mill, causing the screen to stretch. The steel balls farther away from the bolts would run out along the gap between the casting and the screen, causing ball leakage, which seriously affected the normal production and operation of the mill. Utility Model Content

[0003] An object of the present utility model is to provide a tube mill anti-blocking grate plate that can solve at least any aspect of the above-mentioned technical problems.

[0004] A further purpose of the present invention is to avoid the situation that serious ball leakage is caused by long-term use, which seriously affects the normal operation of the mill.

[0005] Another further object of the present invention is to improve operating efficiency.

[0006] In particular, the utility model provides a tube mill anti-blocking grate plate, comprising a plate body, grate holes are opened on the plate body, the grate holes are arranged symmetrically, and bolt holes for fixing the plate body are arranged near the grate holes;

[0007] The grate plate is arranged on the back of the plate body, the grate plate is provided with grate holes, and a plurality of auxiliary welding holes surrounding the grate holes are arranged near the edge of the grate plate.

[0008] Furthermore, the shape of the grate holes is a straight slot hole.

[0009] Furthermore, the diameter of the auxiliary welding hole is 10-20 mm.

[0010] Furthermore, the number of the auxiliary welding holes is 20-30, and the intervals between the auxiliary welding holes are 80-120 mm.

[0011] The technical effects and advantages of this utility model are:

[0012] The utility model provides auxiliary welding holes on the grate plate, which are arranged around the grate holes through the auxiliary welding holes, and welded to the plate casting through the grate holes, thereby increasing the welding density, thereby preventing the grinding balls from running out of the gap between the plate casting and the grate plate during use, thereby avoiding ball leakage and improving the overall service life.
