Screening, pelletising and primary crushing systems provider Haver & Boecker Niagara offers the Scarabaeus pelletising disc to enhance the productivity and profits of mining operations. The “cutting-edge” processing technology allows operations to sustainably produce iron-ore pellets by reducing carbon dioxide (CO2) emissions, while providing heightened efficiency with a 97% production rate of pure iron.
The Scarabaeus technology “effortlessly” pelletises fine materials to improve their storage and transportation properties, while increasing their market value. “The machine seamlessly fits into an operation by offering adjustable inclination, speed, and side wall height to best fit applicational requirements”.
Haver & Boecker Niagara highlighted the Scarabaeus pelletising disc at MINExpo 2021 in Las Vegas.
“We strive to innovatively find and meet the needs of our customers by offering a full-service of customisable mineral processing solutions,” says Haver & Boecker Niagara sales and projects head Jan Lampke.
The mining industry is up against several challenges, especially in terms of sustainability, “which is why our engineers strategically designed the technology to improve and address these issues while minimising the environmental impact”, he adds.
The Scarabaeus pelletising disc is available in a variety of sizes ranging from 1 000 mm to 7 500 mm. It features a unique design that optimises speed and movement to produce high- quality pellet materials. The machine applies a rotating movement combined with water as a liquid-binding agent on the surface of the disc.
The selected material enters the surface of the disc and is pulled along the uppermost side to eventually collect in pellet form in a material bed. The Scarabaeus 7 500 generates a particle distribution of 10 mm to 14 mm, at up to 150 t/h. The compact pellet size aids in the direct reduction process which helps to improve sustainability by reducing CO2 emissions. To ensure an optimum operating system, the parameters of the disc can be automatically adjusted during operation by changing the speed, inclination, mass flow rate and rim height. This feature also helps to minimise recirculation of over- or undersized pellets, Lampke explains.
The processing technology is ideal for a variety of applications, from processing different types of ore and fertiliser to salt and fines.
“We saw a need for a more energy-efficient technology and the rising concern of high- operational costs, so we engineered a solution.”
The Scarabaeus 7 500 pelletising disc serves as a critical part of PROcheck, Haver & Boecker Niagara’s comprehensive service process dedicated to keeping customers’ operations running to the best of their ability. PROcheck applies Haver & Boecker Niagara’s “extensive knowledge” in diagnostics, processing equipment, engineered screen media, original parts, rebuilds and upgrades, services, plant and process engineering to inspect customers’ screening processes to recommend best practices for processing proficiency. An evaluation can be completed quickly, and, if necessary, even while equipment is operating, he concludes.
