HPGR Stu Rollers / Tyres

HPGR stu rollers provide advanced wear protection and durability for a variety of grinding applications.

While customizing the stud grade and design to meet the specific needs of the application, it is possible to ensure that the studs are used effectively and not wasted within a predefined maintenance schedule. By applying different stud hardnesses across the width of the tire, uneven wear is mitigated, ensuring effective size reduction over the life of the roller.

Features and Benefits:

Long Tyre Life

Our stud installation process guarantees repeatable quality and grinding roll performance. High pressure grinding rolls guarantee long wear life with edge blocks that are built to last and remain in place at all times. The tyres can be removed from the shafts and replaced at the end of their service lifetime.

Superior Wear Resistance

HPGR Stu Rollers tyre design combines years of materials development and stud design optimisation to deliver best in class performance. The studded tyre profile enables the formation of a strong protective mineral layer, improving grinding performance and wear life.

High Product Quality at Lower Operational Costs

The unique length-diameter ratio of grinding rolls delivers high product quality, minimises recirculation and reduces operational costs. Our smaller roll diameter optimises the operating gap, fully penetrating pressure through it to exceed the ore’s compressive strength.

Additionally, the spring-loaded lateral wall system provides optimal sealing capabilities which reduce wear associated with varying feed conditions.
