SCREENING
Sandvik Rock Processing now has one of the broadest screening solutions ranges in mining right up to the largest capacity units
Sandvik enhances its expanded range of mineral processing screens with advanced digitalisation
Thanks to recent acquisitions , Sandvik Rock Processing Solutions has expanded its crushing , screening , feeding and wear protection offering which now includes a broad line-up of heavy-duty vibrating screens and feeders perfectly adapted to the world ’ s toughest mineral processing applications , with machines capable of up to 8,000 t / h .
This range is now being enhanced by the newly launched ACS-s condition monitoring system for vibrating screens and feeders , which provides real-time data that enables operators and technicians to make informed maintenance decisions , improving operational efficiency and maximising uptime .
ACS-s is seamlessly integrated into SAM by Sandvik , the company ’ s cloud-based digital assistant designed to support operational excellence in crushing and screening plants . SAM captures data from all connected Sandvik equipment , offering a comprehensive overview of the entire operation . Operators can monitor equipment status , communicate across teams , receive alerts and notifications and proactively order spare parts , all from a centralised platform .
The company recently showcased its new offerings at MINExpo INTERNATIONAL ® 2024 which also included DeckMapp™ Sandvik ’ s unique digital platform for screen deck maintenance .
According to Sandvik , this highly innovative , cloud-based software solution is set to transform screen deck maintenance and drive substantial improvements in the efficiency and operational performance of mineral processing plants .
Accessible via laptop , tablet or mobile phone , DeckMapp™ captures , stores and shares real-time data to present a reliable , single source of truth for all activities within the screen media lifecycle .
A key feature of DeckMapp™ is the optional add-on WearApp™ , an innovative wear assessment system powered by artificial intelligence . With WearApp™ , users simply capture images of worn screening media panels with a smartphone or a tablet . WearApp™ then applies AI to automatically assess each aperture calculating amount of wear , panel efficiency and remaining wear life . This revolutionary application not only saves substantial time , but also delivers far greater accuracy over traditional manual wear assessment methods . With DeckMapp™ and WearApp™ , plant operators can leverage data-driven insights to make smarter , more efficient maintenance decisions , and significantly reduce cost overruns associated with screen deck maintenance . These enhanced capabilities will allow processing plant operators to make more informed decisions regarding their screening media maintenance strategies , such as determining optimal replacement times based on actual open area rather than individual aperture wear .
large double deck vibrating screen , a replacement for an existing screen , which successfully passed the Factory Acceptance Test and was transported to the customer ’ s processing operations at a major quarry in metro Victoria . Designed and manufactured in Perth , this model SWZ 3000 x 8400 was designed by JOEST ’ s WA engineering team and features a state-of-the-art Circular Motion Double Deck Vibrating Screen , twin JOEST ‘ JW330 ’ Series shaft drives , and a custom design to seamlessly fit the footprint of an existing machine .
JOEST Australia states : “ Engineered for one of Australia ’ s largest vertically integrated construction materials companies , this project demanded an innovative approach . Our JOEST team experts rose to the challenge , playing a pivotal role in securing this replacement project . This achievement underscores JOEST ' s capability to design , manufacture , and test high-quality vibrating screens that meet the stringent requirements and expectations of our clients .”
JOEST also has options for screening challenging , inhomogeneous material with its OSCILLA family products . “ Through nearly clogfree operation , products are loosened up enough to separate a fine fraction . Traditional screens are usually not capable of doing this , which is why JOEST Flip Flow Screens from the OSCILLA Family are used for these challenging applications .”
Typical separation cuts lie between 0.5 and 40 mm . These systems are based on the principle of resonance . The internal screening frame reacts to the directly excited external frame in a relative motion . When resonating , the polyurethane screens constantly experience tension and relaxation since they are attached to the internal and external frame with one side each . This principle achieves acceleration rates of up to 50 G on the screen deck .
Redesigned vibroblocks combined with aluminum beams allow for larger oscillation
amplitudes and acceleration rates than traditional Flip Flow Screens . Moreover , this design allows for multi-deck configurations , combining flip flow screens with conventional screens in the upper deck . All available screens from wire mesh and perforated plates to rod screens and PU click systems can be used to fit the application at hand .
