1" Shot Quarry Rock
“Converting to Spokane’s open table design with Si-Tec® wear parts dramatically increased machine throughput while reducing wear parts cost.”
Baseline:
  • Anvil (ANV-80000) and 37", 5 Port Rotor configuration
  • Rotor needs rebuilt every two weeks, costing up to $9,000 each replacement
  • Rotor runs at 1,800 RPM, a very high amperage

Objective:
  • Install 36" table, four shoe configuration with 005-0111-FE Si-Tec® ceramic shoes  
  • Replace standard chrome anvils with 005-2630-FE Si-Tec® Ceramic Anvils
  • Decrease table RPM
  • Increase machine throughput
  • Reduce wear parts cost per ton
Results:
  • Wear parts costs reduced 50%with Si-Tec® Technology
  • 67% Increase (150 to 250 tons/hour) 
Value Delivered:
  • Maintenance time was reduced by 50% resulting in increased machine up-time and improved safety
  • 80% Savings in wear cost per ton
  • Significant energy cost savings with slower RPM

Washington, USA
Abrassive Silicon Sand
"Wear life of Si-Tec® Ceramic Technology increased nearly four times VS standard chrome"
Baseline:
  • Standard high chrome impeller shoes used in abrassive silicon sand crushing operation
  • Average wear life of impeller shoes is 4 hours
Objective:
  • Double the wear life of shoes through Si-Tec® Ceramic Technology
  • Reduce overall costs of wear parts, including maintenance and machine down time
Results:
  • Wear life of Si-Tec® improved usage to 15 hours, nearly four times more than standard high chrome
  • 28% Reduction in opering costs
Value Delivered:
  • Improved deflection pattern improved longevity of other parts within the crushing chamber

005-0111-FE Ceramic Shoe
005-0143-FE Ceramic Feed Disk
California, USA
"50% Less Change outs and 25% reduction in wear parts acquisition costs."
Baseline:
  • Standard chrome shoes last 2 X 10 hour shifts
  • Standard chrome feed disks last 6 X 10 hour shifts
Objective:
  • Increase wear life of shoes by using Si-Tec®
  • Increase wear life of feed disks by using Si-Tec®
Results:
  • Shoes ran for 4 X 10 hour shifts - 2X improvement
  • Feed disk ran for 15 X 10 hour shifts - 2.5X improvement
Value Delivered:
  • 50% Less change outs resulting in increased machine uptime and improved safety
  • 25% reduction in wear part acquisition cost

Baseline:
  • Standard high chrome anvil ring
  • 12 sets of anvils used annually
  • 35,000 tons produced per anvil set
  • 420,000 tons produced annually
Objective:
  • Increase production per set of anvils
  • Decrease production costs per ton
Results:
  • Production tonnage increased 85,000 tons per anvil ring set - 143% increase
  • Anvil ring change outs reduced from 12 to 5 per year
Value Delivered:
  • Anvil cost/ton reduced by 38%
  • Anvil ring change out reduction results in increased machine uptime and improved safety
