ICD Group provided complete design engineering services, fabrication, delivery to the site, and complete site supervision for four (4) replacement conveyors. These conveyors were truss type initial design, but allowed for a future gallery to enclose these dual conveyors. Two (2) dual conveyors from the cooler to a new surge bin and two (2) dual conveyors from the surge bin to the new storage/surge bin inside the processing building were delivered for installation during the same months outage. This involved some 1,400 ft. of 36 wide X 5 ft. deep truss sections; with support bents and gravity take-up sections. Working closely with the construction crew, ICDs site supervisors received the truck deliveries and staged these in an order that could be erected in the shortest time possible to meet the tight deadline. The system was brought on-line in early October with virtually no problems and is producing up to capacity with no ongoing maintenance issues. SOLUTIONSOLUTION

ICD Group designed a new conveying system, secondary screen tower, fines removal conveyor, and transfer conveyor system to tie into the existing circuit delivering iron ore to the DRI module. A 600 MTPH Kinergy screen was purchased to screen the product. ICD Group provided a tower enclosure for this screen and associated fines removal conveyor and chute work to the existing conveyor circuit to the DRI module. The system was installed during a five (5) week outage and then placed on-line. The system now removes up to 5% of additional fines and transfers better product to the DRI module. This helps to reduce the fines for the end DRI product made at this location and transcends into a better shippable product to the various Nucor mills in the States. A complete remote I/O control system was provided to tie into their central control system. SOLUTIONSOLUTION
