INSERT ARRANGEMENT FOR A ROLLER WEAR SURFACE

摘要

A roller for use in devices configured to comminute material has a wear surface. The wear surface comprises inserts that are spaced apart differently to provide a desired wear characteristic in the wear surface. In one embodiment, some inserts may also have diameters or widths that are smaller than other inserts. For example, columns of inserts adjacent an end of the roller may have diameters that are smaller or larger than inserts in columns located near the center of the roller or otherwise positioned between the two ends of the roller. As another example, a middle portion of the wear surface may have inserts that include inserts of a larger or smaller diameter than inserts adjacent the ends of the wear surface.

主权项

1. A roller for a crushing device, the roller having a first end, a second end opposite the first end, and a wear surface that has a width extending from adjacent to the first end of the roller to adjacent to the second end of the roller, the roller comprising:
a first column of first inserts positioned in the wear surface adjacent to the first end of the roller; a second column of second inserts positioned in the wear surface; a third column of third inserts position in the wear surface; the second column of second inserts being positioned between the first column of first inserts and the third column of third inserts; a first insert of the first column of first inserts, a second insert of the second column of second inserts and a third insert of the third column of third inserts being positioned within a first row of inserts extending across the width of the wear surface; the first insert of the first row being spaced apart from the second insert of the first row by a first distance; the second insert of the first row being spaced apart from the third insert of the first row by a second distance that is greater than or less than the first distance; the roller of further comprising a fourth column of fourth inserts positioned in the wear surface, a fourth insert of the fourth column of fourth inserts also being in the first row of inserts, the fourth insert of the first row being spaced apart from the third insert of the first row by a third distance that is greater than or less than the first distance.
