Control cabinet is mounted on main machine (e.g. Fitz Mill) or separately (e.g. lifting device).
For gravity loading, operator simply pushes buttons on HMI to lift up drum from the floor, rotate it 1800, then connect with milling device and lower drum for discharge. Revolution speed of milling device can be adjusted to suit with different kinds of materials. A compact machine with same function is available to handle smaller batch size.
For vacuum loading, operator connects vacuum hose to milling chamber and press button on HMI.
Weight of material is controlled by a scale and viewed through a display.
