13 years is a very long time for a lining. Our PUCEST material is extremely low-wear and keeps its promises. The old lining was removed, new segments were cut from PUCEST sheets in 12 mm with aluminum perforated bleaching insert and screwed into the hopper. When dismantling the hopper, the customer cut away the permanently attached belt seal and our fitters quickly produced a new removable construction on site. This means that all components can be replaced quickly and easily.
