Description
Limestone Transloading facility for Greenfield Limestone truck dump processing and Unit Train Loading of power plant scrubber limestone and sugar rock
Scope
- Turn-key through 3 stages
- Conceptual layout of innovative options, schedule, estimating, and permitting presentations
- Detailed engineering, permitting, purchase of materials & contracts for earthwork and rail
- Balance of engineering, procurement, construction, and commissioning
- Team Development with Customer
- Determination of lowest cost functional option (mass storage vs. just in time process)
- Rail movement conceptualization of spur operations with BNSF
- Design/construct of earthwork, rail bridge, 3 miles of rail siding, 3 miles of roads, culverts, foundations, electrical transmission, substations, MCC’s, and power/controls.
- System components included:
- Truck and stilling shed to accommodate over the road trucks
- Heavy service Stamler feeder with variable speed drive to control system resonance
- Hilfiger wall integral to truck dump (made from native rock for cost and appearance benefits)
- Totally enclosed vibrating screen to separate fines from Sugar Rock shipments
- Overland/over highway (closed tube) conveying system
- Overhead loading surge bins and weigh-feeders to accurately load and certify railcar
- Designed to manage fugitive dust and to be easily expandable
- Two SD-50 locomotives were purchased with the project for siding and loading movements
Results
- All objectives met
- All customer concerns and follow-up accomplished
- Operations and maintenance focused on a superb performance
- Design alternative was given thorough due diligence to verify accuracy
- Passive dust hood technology
- On-time and under budget
- Every step of this project was accomplished in harmony with owners, engineers, contractors, subcontractors, state agencies, BNSF, landowners, and neighbors.
