Lehigh Southwest Cement Co is to upgrade its cement mill in California with a hydraulic roller press pre-grinder with FL Smidth’s Tribomax wear surface protection.
The upgrade is expected to increase the current cement grinding capacity at the Tehachapi plant by 23% by installing and using the hydraulic roller press for pre-grinding.
The Tribomax wear protection will decrease operational cost, says the Danish equipment supplier.
“Tribomax wear solution is the latest wear part innovation from FL Smidth. The product excels by combining a unique material and an innovative use of a welding technology [Plasma Transfer ARC],” FL Smidth says.
“By applying the patented materials together with this special welding technology, the rollers of the hydraulic roller press obtain a built-in surface roughness instead of merely a smooth coating. The result is a surface that is up to 15 times more wear-resistant than an unprotected steel construction and several times stronger than an alternative wear coating. Tribomax wear solution thereby offers a unique resistance against tramp metal and oversize feed, extending wear life and reliability,” it adds.
The contract includes engineering, a new clinker bin, Heavy-Duty Roller Press HRP-C 1.25 with its auxiliaries, weigh feeder, set of belt conveyors, nuisance filters, bucket elevators and new electrical room for this circuit. ??Lehigh Southwest Cement Company is a wholly-owned subsidiary of Lehigh Hanson and part of HeidelbergCement.
