Minox Tumbler Screening Machines have three-dimensional gyratory motion and unique screen cleaning devices. The Five Deck Tumbling Machine screens six different separate fractions while achieving high yields. This unit machine is equipped with a pneumatic deck lifting option. The deck is readily mounted by welding or with bolts and nuts. It includes pneumatic control for lifting and lowering, and is operated by 6 bar compressed air. This simple control allows easy access to the top deck and ball tray. The lower screens, brushes and and/or air knives are simple to reach by removing the R Clips. Screen removal can be removed by one individual as well.
