The Results

Pitt River Quarries has been extremely happy with the consulting expertise and proven results from Epic Polymer’s Shock and Vibration System. What started as an everyday pain for Pitt River has now turned into a long-term solution, with immediate short and long term wins: return on investment and reduced costs for the customer.

Predictable Maintenance

– Due to Epic’s assessment and design of the Shock & Vibration System, the jaw crusher’s maintenance can now be regularly factored at a reduction of 15 hours a week on the affected area
– The solution also eliminates system shut down every six months due to shearing bolts or the repair of structural welds

Extended Machine Life

– The crusher isolation system has been in use for 16 months, with many years of performance left

Overall Total Maintenance Savings on Time and Materials

– Weekly maintenance for replacing nuts, bolts, and washers = $1800
– Weekly welding and fabrication for repairing sub-structure = $900
