Maintenance costs to keep the conveyor running were unacceptably high. Electric costs from running a dedicated 100 HP blower were also excessive.
The plant operates 24 hours per day, 7 days per week and has two 1-week scheduled plant shutdowns per year.
An Olds elevator was installed in January 2014. Due to the extreme temperature, the elevator is designed to accommodate thermal expansion of the lift tube and static screw of up to 4 inches without mechanical interference.
It has since operated for every minute of the plant’s production time requiring no maintenance or service in over 1 year. There have been no breakdowns or lost time due to the Olds elevator.
Annual maintenance costs have been reduced from $45,000 to $0.00. Electrical costs have been reduced by 83%.
