MAINTENANCE WEAR PARTS Although ceramic/metal composites often sell at a premium to the unfortified high chrome iron, the composites typically wear considerably longer. In this case, on a relative cost per hour of operation basis, the operat��� ing cost of Si���Tec ceramic composites is 28 percent of that of the unfortified shoes. Fur��� ther, because the Gen III shoe of this test lasted more than three times as long as the unfortified, using it saves interruptions to production and downtime associated with the change out of two sets of impeller shoes. By reducing the frequency of lengthy shut��� Figure 3 downs for shoe replacement, the operator realizes increased production hours and thus incrementally greater production volumes. It is important to note, that the wear life for a given wear solution will vary in length with variances in feed (size and type), crusher (type, RPM and configuration) and moisture content. Thus, a trial of the same Gen III shoe may have different results with changes to any of the above parameters. For these reasons, Si���Tec ceramic compos��� ites are an ideal wear part solution for use in medium���impact, high���intensity sliding abrasion applications. Ceramic composite wear parts reduce the cost of operation thus supporting higher profits for each op��� erating hour. The savvy shopper will focus on cost of operations rather than simply lowest piece price when selecting wear parts. Information for this report courtesy of Spokane Industries. Bel-Ray Synthetic Gear Oils Win OEM Approval Bel���Ray Synthetic Gear Oil, in ISO Viscosity Grades 150 through 460, has been issued an Original Equipment Manufac��� turer (OEM) approval by Hansen Industrial Gearboxes of Antwerp, Belgium, for use in gearboxes produced and sup��� plied by the company. This high���performance, full���synthetic hydrocarbon and ester combination oil is designed for use in gearboxes on a wide range of equipment including grinding mills, kilns and driers, aerators, pumps, mixers, agitators and hoists. Critical performance capabilities for this OEM���approved Bel��� Ray lubricant have been proven during thousands of hours of use in the field and include the prevention of wear, arrest of existing wear trends, prevention of micropitting on new gears and extended service life. n n Low Temperature Fluidity. The unique synthetic hydrocarbon and select ester base fluids provide excellent low temperature fluidity as well as unsurpassed film formation at higher operating temperatures. Superior Wear Control. Proprietary additive system provides superior wear control and load carrying capabilities. Bel���Ray Synthetic Gear Oil also has OEM approval from Bosch Rexroth (L&S), Caterpillar Global Mining (Bucyrus Interna��� tional), General Electric (electric wheel motors), Siemens (Flender), Joy Global Mining (LeTourneau) and Liebherr. In addition, this premium lubricant exceeds performance re��� quirements of ANSI/AGMA 9005���E02 and DIN 51517 Part 3. Bel-Ray, Suitable for application in enclosed gearboxes, Bel���Ray Syn��� thetic Gear Oil offers machine operators these essential fea��� tures: n Reduced Micropitting. Special additives reduce and prevent micropitting, a form of gear tooth damage that occurs early in the life of gears and is often the root cause of premature gear failure. n Highly Filterable. Clean fluid promotes longer component life by lowering the cost of maintenance and ownership over the life of critical components. 62 ROCKproducts ��� MARCH 2013
