The PP series from Alexanderwerk Inc. is the perfect roller compactor designed to meet all requirements and standards of a compaction process. The machines come standard with the patented Combi-Vent-Feeder®. Through the improved vacuum de-aeration capability, more raw material can be processed in a given period, which leads to a more efficient and profitable operation.
Through the double sided bearing design of the rollers and robust frame construction, a high maximum press force can be achieved. Previously determined process parameters can easily be scaled up to larger production machines. In addition, great flexibility, as well as adaptability to various granule sizes is achievable with the PP series.
To ensure a compact design, all control systems (including hydraulics, vacuum pump, cooling water and air distribution system) are integrated into the control system of the machine.
