The Scarabaeus pelletising disc, supplied by Haver & Boecker Niagara, is designed to enhances productivity and profits for miners. The processing technology allows operations to sustainably produce iron ore pellets by reducing CO₂ emissions while providing efficiency with a 97% production rate of pure iron.
It pelletises fine materials to improve their storage and transportation properties, while increasing their market value. The technology is ideal for a variety of applications, from processing different types of ore and fertiliser to salt and fines.

The Scarabaeus pelletising disc is available in a variety of sizes ranging from 3.2 feet to 24.6 feet (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 collect in pellet form in a material bed. The Scarabaeus 7500 generates a particle distribution of 10-14 mm, at up to 150 tph. The compact pellet size aids in the direct reduction process which helps to improve sustainability by reducing CO₂ emissions. To ensure optimum operating, 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.
Jan Lampke, Haver & Boecker Niagara’s head of sales and projects says, “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 7500 pelletising disc forms part of PROcheck, which applies the company’s knowledge in diagnostics, processing equipment, engineered screen media, original parts, rebuilds and upgrades, services, plants, 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.
