IASTER INSTAIIATION, MO]The overall cost of a mill lining is largely determined bycosts arising from installation and maintenance. Some οfthese costs are directly associated with the time-consum-ing, labour-intensive tasks required by installation orreplacement. Ιndirect costs arise from prοduction shοrt-falls caused by excessive downtime, scheduled as well asunscheduled.

Light-weight Trellex rubber is the key to faster installa-tion and more rational maintenance. This resilient, highlywear-resistant material is ideal for modular elements thatcan be handled by one οr twο men. A typicalTrellexelement weighs 80Ψo less than a corresponding steelsection!

Every element is designed to be positioned and fixed inplace as fast as pοssible. Rubber can be trimmed with aknife or a saw, vrhich makes it easy to adjust the geometry.

DRA|nAτκ sAvl]|Gs l]| τ|lhEFor each ξpe of lining, Trellex has develοped mountingsystems and working methods that generate substantialsavings. For example, a Trellex steel-cap lining can beinstalled in about half the time required for an all-steellining, using a simple, pneumatically operated systembased on a boom and a lifter block.

Αnd a TrellexTW-L welded rubberlining canbeinstalled in a batch millin 2 days - while a stone liningtakes 2 weeks.!
