UNIVERSAL USE IN WET-MILLING TECHNOLOGY
THE DYNO®-MILL UBM MILLING PRINCIPLE
They feature unique bead channels combined with a closed outside contour. The bead channels ensure efficient acceleration of the grinding beads along a precisely defined path. During operation, each of the bead channels creates two efficient grinding circuits between the DYNO®-DISC BC agitator discs that work in opposite directions. Within the agitated bed of grinding beads, the outer contour of the new DYNO®-DISC BC is completely closed. The grinding beads therefore remain between the agitator discs and are distributed evenly throughout the active grinding chamber. This ensures the efficient utilisation of the bed of grinding beads in the DYNO®-MILL UBM. The DYNO®-DISC BC agitator discs are designed for excellent wear resistance and constantly guarantee high performance while reducing the maintenance costs of the DYNO®-MILL UBM series.
