Select options Rotary Trommel Screen Tuffman® Rotary Trommel Screens provide proper and consistent size separation and classification. Trommel screens work through a process using the rotary trommel to separate and size material, providing high output screening of fines and other minus material. As the material passes through the trommel, the smaller debris falls through the screen openings, passing the larger material on for further processing, making trommel screens the best choice for pre-screening before a sorting station or other processes. Tuffman® Rotary Trommel screens are excellent for excavation sifting and separating of materials and are used across multiple applications.
