40 mm TiC Hammers Last 2.5 Times Longer Than Hammers Without TiC Inserts

BACKGROUND

In one clinker cooler campaign at Lehigh Inland Cement’s production plant in Edmonton, AB, Unicast U2183 hammers in manganese (M2) with hard surfacing delivered a wear life of 11.5 months.

CHALLENGES

In order to avoid a costly and impromptu shutdown of the kiln during high season, Lehigh Inland Cement wanted hammers with a wear life of two campaigns instead of one.

SOLUTION

Unicast promised double the wear life with 40mm Titanium Carbide (TiC) M2 hammers after testing a partial set in a prior campaign.

TiC inserts, like those in the hammers, increase a wear part’s structural strength and abrasion resistance, resulting in reduced breakage and a significantly longer wear life.

PERFORMANCE & RESULTS

The new hammers were removed after two and a half campaigns, exceeding expectations by six months. M2 hammers with 40mm TiC inserts therefore outperformed the previous parts by more than 2.5 times.

Hammers needed to be replaced less frequently on the Lehigh Inland Cement plant, boosting the operation’s overall productivity.

SUMMARY

Unicast 40 mm TiC hammers have more than 2.5 times the wear life of M2 hammers with applied manual hard surfacing.
