Lehigh Southwest Cement Company has ordered an upgrade of the cement mill with a hydraulic press pre-grinder with FLSmidth’s latest innovation, the TRIBOMAX wear surface protection, for their Tehachapi plant in California USA.
The upgrade is expected to increase the current cement grinding capacity at the plant by 23% through the installation and use of the hydraulic roller press for pre-grinding. The TRIBOMAX wear solution will also decrease operational cost.
TRIBOMAX wear solution combines a unique material and an innovative use of welding technology. By applying patented materials together with this special welding technology, FLSmidth enabled the rollers of the hydraulic roller press to obtain a vuilt-in surface roughness instead of merely a smooth coating. The resultant surface is up to 15 times more wear-resistant than an unprotected steel construction and several times stronger than an alrernative wear coating, thereby offering unique resistance against tramp metal and oversized feed, and extending wear-life and reliability.
Our customers focus on productivity; they want high utilisation rates and minimum downtime. Wear parts are one of the key components when it comes to reducing overall maintenance cost, and wear solutions like TRIBOMAX reduce the total cost of ownership of the equipment considerably," says Executive Vice President for the Cement Division, Per Mejnert Kristensen.
The contract is an 'Engineering-Procurement-Construction' (EPC) project including 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, Inc. and part of HeidelbergCement, the second largest cement producer in the world.
