Trommel screens The aim is to create order Reliable break-up of material compounds. Even distribution of the materials being sorted. Optimum sizing of materials into different particle sizes. This is what our trommel screens do. BASE FRAME · Robust design for smooth operation and long last of crucial and important rotating parts BEARINGS · Plastic-covered (Vulkollan) drive, support and guide wheels ensure lowvibration and quiet operation even at high speeds SIZING · Different screen plates are available with perforations in various shapes and sizes – including winding protection EASY MAINTENANCE · STADLER trommel screens feature large access walkways, multiple maintenance openings, generously sized and monitored safety doors and interior lighting TRANSPORT · STADLER trommel screens are also available in a bolted version – making extra-large designs easier to transport and assemble. Material is graded into different particle sizes with simultaneous material homogenisation and break-up of material compounds. STADLER trommel screens are built in a modular way. More than 40 different basic configurations are possible. The screening length can be extended to up to 25 meters, by directly combining two units. This table shows an overview of some of the most common screen lengths and diameters.
