SCREENING
Platinum miner PPM ordered the STM-SCREEN™ from General Kinematics with a special hybrid 1.5 deck design
duty screening applications . The Two-Mass drive system responds to rapid increases in material loading by sustaining stroke . Since the STM- SCREEN™ does not dampen , screening efficiency and production continue to be maintained even during surge conditions .”
STM-SCREEN™ retains material up to three times longer than a typical brute force screen , which allows for an optimised material separation as fines have more time to drop out . Equally as important is the ability of the STM- SCREEN™ to process at a higher bed depth without sacrificing throughput . The material
spreads out evenly at the feed end , even at higher bed depths . The increased retention time of the evenly spread material allows for increased screening efficiency at the required capacities .
Due to accelerated wear , common practice in the mining industry was to frequently replace screens , causing unnecessary downtime and using more raw materials to create replacement screens . GK : The STM-SCREEN™ is proven to outlast screen life expectancy by two to five times the current rate , requiring far fewer raw materials to sustain the operation of mining processing plants . It is also proven to reduce power consumption between 50 and 75 % compared to the average brute force screen . Additional increases in capacity are documented from 20 to 40 %, further reducing the energy per ton required for processing material .”
It adds that this increase in efficiency within an existing footprint creates twofold benefits . An increase in processing power can debottleneck and improve productivity without altering any surrounding equipment . Two , increased efficiency can positively impact downstream equipment service life , allowing for a more ’ balanced ’ plant operation .
Haver & Boecker ’ s mainstay F-Class
Haver & Boecker Niagara highlighted its latest screening equipment , technology and solutions for the mining industry at MINExpo 2024 , including having a full-size Niagara F-Class vibrating screen at the event .
Karen Thompson , President of Haver & Boecker Niagara ’ s North American and Australian operations . “ We are proud to be known not just as an equipment manufacturer to our customers , but as a partner with innovative end-to-end solutions to improve their operation .”
The next-generation F-Class features new technology for simplified maintenance combined with maximum performance and longevity . It is now primarily manufactured with vibrationresistant lockbolts instead of the traditional welding used in previous designs . Lockbolts are more effective at maintaining structural integrity during the demanding load-bearing , highvibration operation of a vibrating screen , while making maintenance more convenient , safer and cost-effective . Bar rails are now fastened to the cross beams with lockbolts , making them easy to exchange if they become worn . The machine ’ s double eccentric shaft assembly creates a constant stroke to maintain g-force during material surging , providing constant material
