Performance and durability

IHC Robbins’ tyre and trunnion assemblies are machined to ensure excellent concentricity and subsequent longevity of the running gear. An automated grease supply helps to extend the bearing life, reduces maintenance and operator servicing of the unit.

The helical flighting is crafted from bisalloy, which is a tempered, quenched, and abrasion-resistant steel that offers an optimum combination of hardness and durability in operation. Furthermore, bisalloy’s higher level of wear-resistance equates to longer product life and lower operating costs for our clients. This equates to lower operating costs for our clients.

Safety and costs effectiveness

IHC Robbins’ trommel design allows all screen and flight replacements to be fitted from the outside of the barrel. This removes the requirement for personnel to climb inside the barrel or down chutes to correct or replace screens.


The risk of working in confined spaces is avoided, improving the level of safety in trommel maintenance. Ease of access and quicker turnaround for maintenance provide valuable operational and productivity improvements.
