Mobile trommel, mobile trommel screen, soil trommel
Mobile trommel screens, also known as soil trommels, are heavy-duty machines used in mining and waste processing. They feature a cylindrical drum with holes that separate materials by size as it rotates. Smaller particles pass through while larger ones are retained, making them useful for categorizing waste in MSW plants and other industries.
