Eriez® has announced the expansion of its extensive B-series line of heavy-duty electromagnetic vibratory feeders with four all-new B-HC high-capacity models.

Boasting nearly 70-100% greater capacity than previous models, these feeders offer the widest capacity range in the industry, capable of delivering controlled amounts from just a few pounds to 1,089 t of bulk material per hour, the company claims.

The B-HC line of feeders incorporates an innovative electromagnetic drive that features an exceptionally strong rare earth permanent magnetic armature assembly. This system applies power in both the forward and reverse directions of the feeder tray, ensuring precise linearity and control compared to traditional attract-release systems. The coil-and-magnet assembly is encased in epoxy, protecting it from dust and moisture, eliminating coil movement and significantly extending the feeder’s lifespan.

Equipped with a compact and energy-efficient AC control system, Eriez B-HC feeders provide precise, variable-speed feed rate control with accelerometer feedback. The design eliminates sliding and rotating parts, enhancing profitability and productivity by reducing power consumption and maintenance requirements.

B-HC feeders are ideal for head-load applications below a hopper, efficiently metering bulk materials to belt conveyors, screens, crushers and elevators. Standard and custom-engineered trays can be supplied with features such as dust covers, screens and grizzlies. Abrasion-resistant steel or UHMW liners are optional. 

These feeders support both base and suspended mounting options, with the flexibility to choose between undermount or overhead drive configurations. Rob Yandrick, Eriez Global Product Manager-Vibratory, says that the 65B-HC feeder is already demonstrating its superiority among early adopters, including Washington Mills, a leading producer of abrasive grains. Yandrick explains that Washington Mills previously needed their feeder to run at full capacity to meet material feed requirements. In contrast, the 65B-HC can deliver the same feed quantity while maintaining significant feed capacity in reserve.

The full range of high-capacity electromagnetic feeders is being officially unveiled at MINExpo INTERNATIONAL 2024, in Las Vegas, this week.

The Weir Group has issued its half-year results to June 30, 2023, noting some significant achievements across its Minerals and ESCO divisions.

Headline numbers for the six-month period included a 19% year-on-year jump in revenues to £1.3 billion ($1.67 billion) and a 26% rise in operating profit to £212 million.

Weir Minerals continued to execute on key strategic growth initiatives, and during the first half gained market share in its core mill circuit product categories, it said.

The company said: “We converted 100% of our competitive field trials for large mill circuit pumps, and also rolled-out our latest cyclone technology.”

One highlight in the period came at a large Brazilian iron ore mine, where Weir Minerals upgraded the cyclones to its latest Cavex® 2.0 solution. The new cyclones, which are Synertrex®-enabled, have improved separation and increased mineral recovery by more than 400,000 t/y, according to the company.

Cavex 2 cyclones were launched in 2020, introducing new geometric features to offer performance unmatched by any cyclone in operation at that point, the company claimed. The advanced LIG+ design (patent pending) enables the Cavex 2 hydrocyclones to classify up to 30% more feed slurry, while occupying the same footprint as competitor hydrocyclones, according to Weir.

Weir Minerals says it also made good strategic progress in sustainable solutions during the six-month period and delivered year-on-year growth in comminution. New orders included a pebble crushing plant for a large copper mine in South America and a crushing solution for a potash mine in Canada.

The company also said it saw “very encouraging interest” from customers for its Redefined Mill Circuit, securing orders from large copper mines in South America for coarse particle flotation (CPF) pilot circuits, in partnership with Eriez.

“Through this strategic alliance, we have integrated CPF technology with our latest generation Warman® mill circuit pumps and Cavex cyclones to provide significantly improved recoveries and process efficiencies for our customers,” it said. “Once operational in the September quarter, these plants will be important reference sites for the industry.”

Around a year ago, Weir Minerals and Eriez Flotation announced a cooperative agreement to design and develop CPF systems. This allows both companies to better connect the Eriez equipment with the slurry classification and conveying expertise of Weir Minerals, according to Ricardo Garib, Division President of Weir Minerals.

Weir Minerals also launched its new, proprietary digital intelli-solutions for pumps, cyclones and high pressure grinding rolls which, coupled with its Synertrex 2.0 platform, captures critical machine health data and enables remote condition monitoring.

It concluded: “We continued to invest in research and development of our core technologies including new materials and polymers, and upgrades and range expansions for our industry leading Warman slurry pumps.”

Weir ESCO, meanwhile, reported that the number of mines using Motion Metrics™ AI-enabled vision technology increased during the first six months of the year, with new orders including a package of five ShovelMetrics™ and five LoaderMetrics™ systems to be deployed across all large mining machines at an iron ore mine in Western Australia.

“The division made excellent progress in growing market share in mining attachments, with a 37% year-on-year increase in orders,” it said. “A particular highlight included converting four cable shovel buckets from competitor products to ESCO technology for a large North American copper miner.”

The division also provided an update on trials of its proprietary ore characterisation technology, which has been leveraging the BeltMetrics™ solution from Motion Metrics positioned above a conveyor directly after the crusher in the flowsheet at an unnamed mine. As well as using the rugged vision technology Motion Metrics has previously used, the company is also incorporating hyperspectral imaging into the mix for this trial.

It reported: “Field trials of our proprietary ore characterisation technology were successfully completed during the first half. Tests enabled critical data to be collected and validated the performance of the technology in a real-world environment.”

Development has now progressed to the next phase focused on exploring “novel illumination” technologies to enhance minerals characterisation, it added.

New Motion Metrics capabilities and functions were launched during the six-month period, including an upgraded lens cleaning solution that enhances machine vision capability and improves response times.

“Other technology investments included development of a new series of mining attachments that, once launched, will expand our addressable market,” it said.

Eriez Magnetic Mill Liners boost safety, energy efficiency and durability at Nexa Resources mine

A new report from Eriez® reveals how a set of Magnetic Mill Liners (MML) are significantly improving safety standards, energy efficiency and operational longevity at a Nexa Resources operation in Peru.

The MML is a wear-resistant steel-encased magnet that combines the best qualities of steel and magnetic liners, according to Eriez.

The report highlights the superiority of MMLs over conventional liners by describing the numerous benefits these advanced liners offer. Each MML is composed of individual sections that are much lighter than traditional liners, facilitating safer and easier installation procedures, Eriez says. Weighing only 20-40 kg per section, the MML eliminates the requirement for specialised cranes within the mill, streamlining operations and enhancing safety protocols. Nexa even credits the MML installation with contributing to the company’s achievement of a major Peruvian safety award.

There are considerable environmental advantages associated with the implementation of MMLs, according to Eriez. Heavier steel liners require significant fuel consumption for transportation and material handling while lightweight MMLs can be installed by hand. Additionally, Nexa reports a significant reduction in noise levels with the MML, creating a more favorable work environment overall.

The case study also highlights the energy-efficient aspects of MMLs. In traditional ball mills, small ball chips do not contribute to the grinding process, leading to wasted energy. However, MMLs effectively eliminate the presence of small ball chips, resulting in energy savings of up to 11% during the grinding process, according to Eriez.

The exceptional durability of MMLs is another standout feature discussed in the report. Unlike conventional liners that necessitate frequent replacement, the Eriez MML has garnered a track record of success through many installations in diverse mining operations worldwide, including iron ore, copper, nickel and gold mines, as well as other non-ferrous mines. These installations provide evidence that MMLs outlast rubber or metallic liners by two to three times, Eriez states.
