Cogmatic fabricates rolled drum segments from ¼” to 1″ thick steel plate or bar stock. These drums can be up to 8′ (eight feet) in diameter and 40″ (forty inches) wide.

Commonly used in standard or custom heavy-duty construction equipment, drum segments are machined in several pieces for easy assembly. The assembled rolled drum segments are used with trommel screens. Typically, trommel screens are revolving cylinders that are used to sort materials or remove debris.
