STEINERT Australia’s open day at its Melbourne headquarters and production facility in early June, attracted mining and quarrying professionals from Australia and overseas. Almost 50 guests saw STEINERT’s sensor sorting and metal separation solutions, and heard about the company’s activities throughout its Australasian markets.

The open day was held in conjunction with the final day of Curtin University’s Ballarat Gold Symposium and, along with conference delegates, it attracted others interested in STEINERT’s world-leading sorting and separation technologies.

The event included a ‘lunch and learn’ session, a tour of the production facility and networking drinks.

A number of STEINERT Australia personnel explained various aspects of the company’s technology to guests. Among them was managing director Johan van Zyl, who outlined the company’s work in this region along with the rationale behind the division becoming the agent for HAZEMAG and allmineral equipment.

He explained that both companies complement the magnetic separators and sensor sorting technologies developed by STEINERT while also spreading the influence of all three across the region.

STEINERT utilises a broad spectrum of technologies to meet a wide range of sorting criteria. From classic magnetic separators up to innovative sensor technologies, STEINERT has many solutions for different applications.

Following the presentations, guests were led on a tour of the facility and saw a range of STEINERT magnetic separators for mining and quarries, including mains power (MP) and permanent, self-cleaning overhead suspension magnets and wet and dry drum separators. The 230-volt MP magnet can be run directly from any three-phase socket within the work site and is suitable for belts of up to 1200mm in width.

A highlight was a demonstration of the STEINERT KSS combination sorter, led by process engineer Gideon van Wyk. The KSS can sort coarse composite mineral ores from waste materials using a range of sensors. The unit’s sensitivity can also be fine-tuned for high upgrade ratios or maximum recoveries. It is the only sorter utilising three sorting techniques or any combination of the three in the one process.

The demonstration showed the machine’s capability of sorting rocks with economic value from waste rock. It did so using samples of quartz and waste rock with the light coloured quartz automatically sent to the ‘accept’ pile and the dark waste rock sent to the ‘reject’ pile.

Using sophisticated technology that is unique to STEINERT, the KSS can be ‘taught’ to sort coarse composite mineral ores from waste materials. Using metal product quality, material density or colour, the unit adapts to changing market and processing needs by allowing any combination of the colour camera, 3D camera and induction sensor into one independent solution.

The unit’s sensitivity can also be fine-tuned for high upgrade ratios or maximum recoveries.

STEINERT KSS systems are equipped with active valve control for a reduction in compressed air consumption versus standard air ejection systems. The required air blast pressure and number of controlled compressed-air valves can be optimally adjusted for the materials being sorted. The nozzle bar is extremely precise due to its grid of nozzle pairs at 12.5mm intervals.
