The emphasis on liner design to ensure efficient mill operation
has grown, particularly as mills have increased in size. The
extent to which a liner effectively protects the mill, imparts
energy and controls the mill charge, impacts on the total
ownership costs for plant owners and operators. In general, the
harder the material fed to a grinding mill, the greater economy
achieved using rubber liners.
- Versatile, economical, and efficient –
Vulco® wear resistant rubber and metal cap mill
liners provide.
- Lower installed cost – Since rubber and metal
cap mill liners weigh up to 80% less than steel alone, they are
faster, easier and safer to install
- Operating efficiency – Vulco rubber compounds,
specially formulated for maximum tear resistance and resilience,
increase wear life and reduce downtime. Liner profiles are custom
engineered to fit specific geometry and operating conditions.
Reducing the mass of lining systems commits greater charge weight
to be utilized, increasing throughput
- Reduced maintenance – The low profile T-track
system eliminates the need for frequent inspections, repair, and
bolt tightening. Rubber conforms to the mill’s internal surface
creating a seal that prevents leakage and slurry erosion of the
mill shell. Faster change outs and longer wear life with fewer
maintenance interruptions mean greater mill availability and
performance
- Health and safety – Rubber liners
significantly reduce the generated and transmitted sound level
associated with grinding. The risk of strain injuries during
installation is reduced because of the lighter weight of the
liners. Converting to rubber linings from metal can reduce the
number of components to be handled
- Lower operating cost – Next to the ongoing
cost of electrical power and grinding media, mill liners are the
highest recurring expense for a mineral grinding operation.
Compared to traditional metal liners, the benefits of rubber liners
effectively reduce this expense
