Spare and wear parts for HIGMill

The drum segments and components have been designed to make maintenance simple and maintenance intervals long for more sustainable operation. The casing is flanged vertically, allowing it to be split down the center into two halves and moved apart on a railing system. After exposing the internals, changing discs and liner segments can be done individually. 

Disc wear is even around the circumference. Wear is faster in the bottom part and typically the lowest discs are replaced a few times before the total set is changed. For a total set change, a spare shaft, ready for installation, is an option. Components are lined with polyurethane or rubber depending on the application.
