In extrusion processes, it is important to create consistent product flows, but often bulk goods being fed build up in the extruder inlet area or adhere to the walls of the hopper. The ROWEFLEX® pre-hopper offers the customer the flexible solution for merging several bulk goods. Thanks to its individual design, it can be flexibly adapted to your system and, as opposed to conventional metal hoppers, ensures continuous product entry. All discharge aids are located outside the product space and do not impair the free product flow, meaning that the product is not contaminated in any way. ROWEFLEX® pre-hoppers are available in several standard designs and can be customized to the customer’s system. We match your needs flexibly in planning and development.
