The roller wheel tower features a cam drive mechanism fixed to the input shaft, incorporating two flat cams designed with parallel conjugate cams. This separator achieves the function of dividing the output shaft by rotating the roller wheel tower through the engagement of the two flat cams on the input shaft. It is suitable for conveying belts with larger pitches and for intermittent divisions with longer dwell times. Additionally, the three-piece heavy-duty design is more appropriate for fast and long-pitch conveyances, and also has a longer dwell time compared to the two-piece version.
