Trommel screens, including compost trommels and mobile trommel screens, are cylindrical drums with perforated holes used in mining and waste processing. They mechanically sort materials based on size, separating smaller particles that fall through the holes from larger ones. Widely used in MSW plants and waste processing facilities, mobile trommel screens offer versatility and efficiency in material sorting and recycling.
