Ring-roller (micro powder) mills

Rollers run against multi-tier rings inside a rotating assembly. Small wear faces, high unit pressure — grade selection matters more here than anywhere else.

MATERIAL SELECTION

Which grade should you be running?

The right answer depends on what you grind, not on what we would rather cast.

High impact, coarser feed

High-manganese grades work-harden under impact and hold up where lumps are hard and the loading is uneven.

High abrasion, finer feed

High-chromium cast iron and Ni-Hard usually win on quartz, high-silica limestone, clinker and slag.

Severe abrasion with impact

A composite or hardfaced part, with the overlay planned into the maintenance cycle rather than treated as a repair.

We will recommend against our own margin when it is the right call. If a cheaper grade will last you as long, we will say so — a part that comes back too early costs us the account.
