This is 1 of 2 180 degree sprocket segments for a trommel that is currently in the field. The existing sprocket has worn out and needs to be replaced in order to continue the task at hand. These sprockets are made in 180-degree segments to make it easier for mounting on the cylinder of the trommel as well as shipping them to the location. Once mounted, the ends are welded together to make a continuous sprocket. Cogmatic can produce these sprockets in diameters up to 18’-0”.
