Three TAKRAF X-TREME class sizers supplied to a large bauxite mining operation in Guinea are, the OEM says, fully delivering on their promise of exceptional reliability and wear behaviour.

Commissioned in late 2018, the sizers had, as of the end of February 2021, crushed more than 27 Mt of bauxite ore and were still operating with their original set of wear parts.

The sizers were supplied as part of an important production expansion project at the mine. This project, awarded in late 2016 to TAKRAF as an EPC contract, encompassed a comprehensive wagon unloading, crushing and conveying system.

The TAKRAF sizers included within the overall system comprised one 3,600 t/h primary TCS-X 14.35 located in the pit beneath the wagon tippler; and two 1,800 t/h secondary TCS-X 08.30 located in the crushing building.

Both the primary and the secondary sizers are from TAKRAF’s X-TREME class sizer range. This range was developed to provide extended reliability and availability through a heavy-duty drivetrain, robust shaft and bearing assemblies, and the use of advanced wear resistant materials.

Ease of maintenance is another advantage of the TAKRAF sizer, with the primary sizer installed on site featuring a bolted tooth system to enable easy and quick replacement when sufficient wear has been experienced, the company says.

Conor Mitchell, TAKRAF Product Manager – Roll Crushers, said: “The combination of high reliability and long lifetime of wear parts means significantly higher machine uptime and that ends up translating into increased productivity for this bauxite operation. These performance levels reinforce that our X-TREME class sizer line provides maximum reliability and availability in difficult conditions, which is something the market has been calling for quite some time.”

Tenova TAKRAF says the company’s high pressure grinding roll (HPGR) technology, among other developments, will be highlighted at the upcoming Bauma fair in Munich, Germany, on April 8-14.

The company said, for the first time, show visitors will be able to have a complete overview of the company’s entire service portfolio, which ranges from project development services to technical studies on comminution and minerals processing, innovative fabrication solutions, various technical services and comprehensive after-sales support.

“With a view to further developing their capabilities within the market of the comminution industry, TAKRAF continues to develop their range of roller presses, with a scale model of a HPGR on display at the booth (pictured),” the company said.

Two of these machines are being manufactured at the company’s specialised fabrication facility in Lauchhammer, Germany. These machines can each handle more than 907 t/h of cement clinker, with each machine incorporating rolls with a diameter of 1,800 mm and a weight of more than 450 t per roller.

“In order to meet the challenging longevity requirements of such a machine, each roll surface is protected from wear by weld hardfacing for cement applications, and with tungsten carbide inserts for ore processing,” TAKRAF said.

The company continued: “With the integration of the well-known DELKOR and Tenova Advanced Technologies (formerly Bateman Advanced Technologies) brand of products into TAKRAF as specialised product lines, the company’s portfolio for the minerals processing and beneficiation sectors has been considerably enhanced.”

At Bauma, visitors will be able to focus upon the company’s capabilities in minerals processing, including solvent extraction and lithium recovery; as well as flotation, thickening, filtration and dry stack tailings, according to TAKRAF.

The company will also use the event to highlight its Mining Technology Centre, TAKRAF said.

“Technical studies, which compare the techno-economic aspects of different system or equipment layouts are an intrinsic part of every investment process. The quality of the study strongly depends on the experience of the study team and the level of customer involvement,” the company said.

“Based upon a common understanding of the weighting of all such decision criteria, the transfer of technical and operational experience and expertise, even beyond their own portfolio, is a key driver in enabling the customer to make a competent decision regarding the optimal solution for the specific conditions of their particular mine.

“More and more customers appreciate the added value provided by the studies as part of the engineering service portfolio, and for this reason, the company has decided to restructure and tailor their services even better in order to best meet customer requirements.

“TAKRAF’s Mining Technology Centre will be present and on hand to present the myriad of possibilities and benefits of innovative study approaches to demonstrate they are pursuing this strategy together with their customers.”

TAKRAF said, in order to provide additional benefits and services to the company’s customers based on new digital technologies, several R&D projects in the field of the industrial internet of things have also been advanced.

“In an attempt to find the most suitable technology, which results in the greatest possible benefit for the customer, first pilot machines were equipped with remote data collection and evaluation systems.

“Utilising a combination of edge computing and a proprietary azure-based platform established by Tenova, TAKRAF is able to develop applications that provide valuable insights of the company’s machines through modern and intuitive interfaces across any remote location.

“First results evince that this information can greatly assist in reducing downtime by identifying problems before they escalate into major issues and optimizing machine design, operation and performance.”

Implementation of more advanced analytics and machine learning strategies are currently on the company’s R&D agenda, TAKRAF said. “In addition, remote support solutions can also be offered.”

The company said: “This enables a remote experts-team to provide on-site assistance to the local commissioning or maintenance personnel using smart glasses and an appropriate software tool.

This is a great solution for reducing reaction times and as a side effect for reducing or even avoiding costs for expensive and time-consuming trips to the destination area.”

The company’s stand will be located in hall C2, stand 349 at Messe München in Munich, Germany, during the event.

Tenova HYL has been contracted by HYBRIT to supply its direct reduced iron (DRI) solution as part of the world’s first fossil-free steel-making technology in Sweden.

HYBRIT, a joint-venture project between SSAB, LKAB and Vattenfall, was established in 2016 with an aim to replace coking coal, traditionally needed for ore-based steel making, with hydrogen, a fossil-free steel-making technology. This would result in steel with virtually no carbon footprint, the company says.

The Tenova HYL DRI technology will be used at HYBRIT’s pilot plant in Luleå, Sweden, which is expected to begin operations in 2020.

“Thanks to the unique characteristics of its process and its specific expertise in direct reduction with high content of hydrogen, Tenova HYL perfectly fitted with HYBRIT project,” Tenova said.

The company added that the “manoeuvrability” of production of the DRI module was another contributing factor, adding flexibility in terms of operations.

Mårten Görnerup, CEO of Hybrit Development AB, said: “By using state-of-the-art production technology as a starting point, we will more quickly reach our goal of a fossil-free future.”

HYBRIT’s goal is to have a solution for fossil-free steel by 2035.
