56 E&MJ • MARCH 2019 SUPPLIERS REPORT Ionic Engineering designed a material handling system capable of packaging up to 32 metric tons per hour (mt/h) of cop - per concentrate in bulk bags by integrat- ing a Flexicon automated bulk bag filling system into the existing processes at Vale Canada Ltd.'s Sudbury mining complex, Flexicon Corp. reported. The system is comprised of dual-bulk bag fillers, roller conveyors and a central pallet dispenser. Ionic also designed the electrical and control systems, sourced la- beling machines and other equipment, de- signed safety systems, and performed the systems integration including program- ming, electrical and safety. The Ionic En- gineering team also performed additional mechanical design and safety engineering. The system is initiated when a forklift loads 10 to 14 pallets at a time on to the pallet dispenser. When one of the bulk bag fillers calls for a pallet, the dispenser lifts all except the bottom pallet, which is sent to the filler by the powered roller conveyor. A turntable then rotates the pal- let 90° to align it with the filler. Once a pallet is in place, the filler's swing-down fill head lowers and pivots from horizontal orientation to vertical, po- sitioning the discharge chute and bag strap hooks within reach of an operator standing on the plant floor. Once the operator places the bulk-bag loops over automated latches, fits the bag spout over an inflatable spout seal, and pushes the inflator button, the filling cycle is fully automatic. The filled bag is rolled onto a gravi- ty-feed roller conveyor toward a ramp that stops it in position for unloading. Then a forklift transfers the filled bags to a stor- age area, ready for shipment to customers. In addition to fitting into the limited space available, the dual-bulk bag filler configuration provides capacity, flexibility and redundancy for the bag filling process. Tenova HYL Tapped for Direct Reduction Module in Bolivia Tenova HYL, a Tenova company, was recently chosen by China's Sinosteel Equipment and Engineering as the tech- nology provider for a Direct Reduction Micro-Module for Empresa Siderúrgica del Mutún (ESM) at Puerto Suárez, Santa Cruz Department, in Bolivia. Tenova HYL's Direct Reduction technology will be used for the first stage of the project, which will include a 250,000-metric-tons-per-year (mt/y) direct-reduced iron (DRI) facility, a 650,000-mt/y concentration plant, a 400,000-mt/y pelletizing facility for Mina El Mutún, and a steel plant with a contin- uous caster and rolling mill with a total ca- pacity of 190,000 mt/y of long products. The module will use the state-of-the- art ENERGIRON Zero-Reformer Process and will be capable of supplying the melt shop with high-quality DRI with metalli- zation levels of 94% and an adjustable high-carbon content in the range of 3% to 4%, Tenova HYL reported. The 250,000-mt/y plant is expected to be in operation in mid-2021. Sandvik Closes on Acquisition of AVS Sandvik announced it completed acquir- ing U.S.-based Artisan Vehicle Systems. Artisan is a startup company that in 2017 had revenues of $12.3 million and ap- proximately 60 employees. It is known for its battery-powered equipment solutions. Artisan will be a business unit in the Load and Haul division within Sandvik Mining and Rock Technology. The parties agreed not to disclose the purchase price. Botswana Diamond Mine Gets Weba Solution Weba Chute Systems reported a recent solution deployed to a diamond mine in Botswana solved maintenance challenges and ensured more uptime for the custom- er's operation. The mine was replacing transfer chutes almost every three months. Run-of-mine material, with lump sizes up to 1,200 mm, is fed via an apron feed- er onto a grizzly feeder, with the oversize material reporting to the jaw crusher. Larger particles of lump kimberlite, as well as uncontrolled material, posed an ongoing challenge to the transfer system. Another challenge was how the conveyor received material from the grizzly under- pan and jaw crusher discharge. The technical team from Weba Chute Systems assessed the challenges and, in partnership with the mine, engineered a material handling solution. The purpose-designed solution fea- tured a transfer chute to better handle the 1,200 mm lump sizes. An integral swing mechanism reduces the impact on down- stream components. The solution featured an engineered transfer point solution to enable con- Vale Canada Gets Automated Bulk Bag Filling System The pallet dispensing and bulk bag filling systems are equipped with automated controls, safety systems and guards.
