◢ Safe raisedrill carriers

Transporting raisedrills and related machinery using generic mining equipment can result in damage or delays. Recognizing the need for a product that is designed to move them safely, Redpath introduced the Redtrax raisedrill carrier to its fleet. It eliminates the need for telehandlers, load-haul-dump machines and forklifts to do this work, thereby freeing them up to be used elsewhere at the mine. The carrier is designed to transport Redpath’s Redbore 30, 40, 50 and 70 raisedrills, although it can accommodate other drills on the market. Its diesel fuel engine meets emission standards and reduces workplace noise levels. “Redtrax allows the team to execute the project requirements independently from site to site, reduces damage of drill components as the unit is purpose built, and safety features keep our workforce available to execute the client’s request,” said Bryan Maille, Redpath’s raisebore superintendent.

◢ Military-grade refuelling system

Many remote mines lack the refuelling capability required to accommodate large aircraft on their airstrips. That is why SEI Industries decided to make its High-Pressure Aviation Refuelling System (HPARS) – originally designed for military training and operations – available for commercial use. The system weighs about 1,800 kilograms and is built on a skid so it can be easily moved. “It’s a portable system that [companies] can take with them, but it’s also heavy duty and substantial enough that it can stay in one place for a long period of time,” said Robin Cnudde, the company’s Canadian sales manager. HPARS is fully self-contained, weather-proof and explosion-proof. It also comes equipped with a drip tank, a lighting system, an emergency stop control system and a fire extinguisher. Using a self-priming centrifugal pump, HPARS has a maximum flow rate of 750 litres per minute and runs on an electric motor.

◢ Taking the next step

When choosing flotation technology for a plant, mineral processors look for high recovery rates and low operating costs. After seven years of development, FLSmidth unveiled its nextSTEP rotor/stator for use in forced-air flotation equipment. The product consistently draws 10 to 15 per cent less power than what were the most energy-efficient models on the market, according to Frank Traczyk, the company’s global flotation technology director. The team designed the rotor/stator with horizontal slots, enhancing overall recovery by one to two per cent. After testing more than 200 combinations, “With this particular stator/rotor combination we got better mixing, better suspension and a finer bubble,” Traczyk said. “Those fine bubbles really enhance the recovery.”
