Continuous screen changer / hydraulic / double-piston - 1 300 - 10 700 kg/h | CSC-PE
Maag's continuous screen changers are based on a proven double-piston design that operates without any additional seals. This sturdy construction delivers a reliable and leak-free filtration of polymer melts for many years, no matter what the size or configuration of the system. On the inlet side, rheologically optimised flow channels distribute the melt flow in even quantities into the screen cavities. The breaker plates are fitted with screen mesh material to match the filtration grade required. After the screens, the two cleaned partial melt flows are brought together and exit the filter housing simultaneously. To change the screen, the pistons are ejected from the housing one after the other using hydraulic cylinders. Once replaced, they are returned to their production position in the same way. During the brief screen change process, the melt flows continuously through the other piston, thereby ensuring the system's constant operation.
