Cost Efficiency

Longer service life, lower running costs

Uninterrupted availability is of paramount importance to HPGR users. They expect a technically reliable and cost-effective wear protection solution that maintains proper operation even under severe service conditions. The HEXADUR® wear protection solution ensures a substantially extended, uninterrupted service life compared to hardfacing or wear-resistant castings.

Thus HEXADUR
® rollers generate considerable cost savings due to their very low wear rate. Their even usage pattern also provides consistent operational conditions in terms of throughput and grinding efficiency over their entire service life.

As a result, the higher entry costs (CAPEX) of the HEXADUR® system are more than compensated for by cost savings over time (OPEX) resulting from energy-efficient, maintenance-free and trouble-free operation.

At Norcem AS for example, maintenance-free operation of HEXADUR® rollers in cement grinding has provided convincing proof of concept for this wear protection system. It has been shown that costs can be reduced by up to 75% over time through full operational availability over a prolonged period.
