MX Mantle helps eliminate several change-outs per year
To further maximize the efficiency of the crushing process, Mr. Razo wanted to extend the maintenance intervals and increase the availability of the primary gyratory crushers. Previously, the mine used 5 to 6 mantles per concave set, with each mantle change-out taking approximately 60 hours during which the crusher is not in operation. Translated into crushed tons, 60 hours falls between 75,000 and 100,000 tons. By switching to Metso Outotec’s innovative hybrid composite MX Mantles with double longer wear life, the mine was able to cut the number of change-outs required, thus adding valuable production hours.
Mr. Razo is happy with the preliminary results.
“The test we ran with primary crusher #2 resulted in us using 2 sets of mantles. Using other suppliers, in the same 13-month period, we would need up to 5 sets of mantles. So, 2 vs. 5”, he recounts.
In addition to the improved mantle, Metso Outotec supplied concave segments in WX60 alloy steel, which provided a 30% wear life improvement compared to the previous solution, further adding to uptime and production benefits.
