Brokk provides plug-and-play remote-controlled breaking solution

Brokk, a leading manufacturer of remote-controlled demolition robots, has introduced the Brokk Pedestal Boom, a compact, stationary breaker boom system for the mining and aggregates industry.

The new machine range allows producers to apply the power and precision of Brokk’s demolition robots to primary breaking tasks that feed mobile crushers, jaw crushers, gyratory crushers and grizzlies.

The Brokk Pedestal Boom, Brokk says, offers an unrivalled range of motion, pairing Brokk’s three-part arm system with 360° slewing for maximum versatility in underground applications. The unit can be operated with either the tethered remote or from a control room.

Depending on network configuration, the machine can be manoeuvred from 2,000 m away or longer, using Brokk’s SmartRemote™ technology to increase safety and efficiency.

The standard remote operation solution features remote-control, intuitive controls and professional-grade radio technology with a 300 m working range, allowing operators to maintain the best view possible while staying safely out of harm’s way.

The networked remote operation solution allows operators to control the robot while sitting in an office, which, depending on network configuration, can be located 2,000 m away or longer. The machine is connected and operated over Ethernet or Wi-Fi.

The standard video option includes two cameras on the machine and an operator’s desk with integrated controls and video screen. Upgrades are available, including additional cameras for better visuals and optical zoom cameras. One control system can be paired with up to six Brokk Pedestal Boom systems.

Brokk will showcase the Brokk Pedestal Boom (the Brokk 300) and highlight other robotic mining solutions at MINExpo 2021, September 13-15, in Las Vegas.

Martin Krupicka, President and CEO of Brokk Group, said: “Brokk saw an opportunity to give our customers a better solution for breaking oversize rock in crushing and grizzly applications. We’ve developed technology that is powerful, compact, flexible and easy to install. The new Brokk Pedestal Boom provides a plug-and-play solution that is perfect for underground spaces with low headroom or other space constraints. We are leveraging our 45 years of experience and proven technology platforms to create a smart, safe and user-friendly solution.”

The Brokk Pedestal Boom is based on the proven arm system and power pack of Brokk’s demolition robots. The machine body is then mounted on a pedestal, rather than tracks. This allows the machine to be installed in a stationary position next to a crusher or any area where primary breaking is needed, the company says.

Unlike existing breaker boom options in the market, the Brokk Pedestal Boom system integrates the power source and arm for a compact breaking solution with just a single power cable. No external power pack or hydraulic hose connection is needed.

Model sizes for the range include the Brokk 200, Brokk 300, Brokk 500 and the Brokk 900 Pedestal Boom, which is capable of producing 3,050 J/Nm at a rate of 330-680 blows per minute with the BHB 1500 hydraulic breaker to power through even the toughest rock formations.

The Brokk Pedestal Boom offers more flexibility in underground and confined space applications, Brokk says. The three-part arm design allows producers to reach closer to the crushers and manoeuvre in as little as 1,800 mm of height clearance. This, paired with the unit’s 360° slewing capabilities, means operators can maintain the best angle against the material for efficient breaking.

Brokk’s compact and more flexible three-arm system also makes maintenance and switching attachments easier, especially in areas with space constraints.

The Pedestal Boom comes standard with a corresponding BHB hydraulic breaker for optimal efficiency and breaking capacity.

“Worker safety is a major focus for many companies and Brokk actively searches for ways to make every aspect of our customers’ processes safer,” Krupicka said. “Over the years, our demolition robots have helped mechanise a number of high-risk, heavy labour tasks such as scaling, drilling and secondary breaking. The new Brokk Pedestal Boom range addresses one more challenge, enabling customers to efficiently complete work without any health and safety risks.”

thyssenkrupp to deliver next gen gyratory crushers to Iron Bridge magnetite project

thyssenkrupp is to make history in Australia, with plans to install KB 63-130 type gyratory crushers at the jointly owned Iron Bridge magnetite project, in Western Australia.

The company said its mining business unit had been awarded consecutive contracts to supply these two gyratory crushers and a radial stacker for Iron Bridge, which is a joint venture between Fortescue Metals Group subsidiary FMG Iron Bridge and Formosa Steel IB Pty Ltd.

Iron Bridge will be a new magnetite mine, around 145 km south of Port Hedland in the Pilbara region of Western Australia. Delivery of first ore is scheduled for mid-2022.

Johann Rinnhofer, CEO of thyssenkrupp’s mining business in Australia, said: “We are proud to be part of this project and excited to install two of thyssenkrupp’s next generation gyratory crushers here in Western Australia. These high capacity crushers are considered to be the largest and most powerful in the world and are unrivalled when it comes to crushing blasted hard rock and ore.”

The KB 63-130 type gyratory crushers will be the largest ever installed in Australia, according to thyssenkrupp, with the crushers processing raw iron ore material from the pit and transfering it to a receiving conveyor.

The slewing and luffing radial stacker, meanwhile, will be used to stack secondary crushed magnetite iron ore onto a stockpile at the mine.

The Iron Bridge project will deliver 22 Mt/y (wet) of high grade 67% Fe magnetite concentrate product, according to FMG.

The first stage of the project was completed successfully by building and operating a full-scale pilot plant at the North Star mine site. This pilot project included the use of a dry crushing and grinding circuit, which FMG plans to leverage in stage two.

The second stage of the project comprises the construction of a large-scale process plant, and port
infrastructure to support the production of 22 Mt/y (wet).
