Kwatani wins major screening order from Central Asia copper mine

Competing with leading OEMs from around the world, vibrating screen specialist OEM Kwatani says it has snatched a mammoth export order for over 70 screens from a mining operation in Central Asia.

The order was signed in April with a large copper mine in the region, which boasts a production rate of 35 Mt/y. According to Kwatani General Manager Sales and Service, Jan Schoepflin, the machines will be rolled out and delivered over a tight schedule of just eight months.

Kwatani, now part of the Sandvik group within the Sandvik Rock Processing Solutions division, is already hard at work manufacturing the large and medium-sized screens at its South Africa-based manufacturing facility.

“This is Kwatani’s largest order to date and is probably the largest single order for screens ever placed with a company in Africa,” Schoepflin says. “We are proud to have won such a prestigious bid in the face of intense competition, showing how our global reputation has been growing.”

The order is for large double-deck multi-slope screens, which feed high pressure grinding rolls, as well as for single-deck linear screens feeding concentrators. The screens in this order will be installed on isolation frames to minimise the extent to which dynamic loads affect the plant’s building structures, the company says.

Kwatani says it is well known for its design, manufacture and servicing of large, robust screens which are engineered for tonnage.

“As the largest OEM for vibrating screens and feeders in Africa, we have had great success on the continent and abroad with our large ‘banana’ screens,” Schoepflin says. “These and our other custom-engineered screens have been supplied to over 50 countries to date.”

The stringent and lengthy technical adjudication for this project was conducted for the mine by two leading international project engineering houses. The size and value of the order ensured all the mining industry’s foremost screen suppliers participated in the bid. Other indicators of the order’s scale are that the screens will consume around 700 t of steel, and will altogether be fitted with 21,000 screening panels.

Schoepflin notes that an important consideration for customers is not only the proven quality and performance of its screens, but Kwatani’s ability to deliver on time.

“Any large capital expenditure decision on a mine is taken with time-sensitive factors in mind,” he says. “For instance, the delayed delivery of critical equipment can prevent a mine from meeting its planned production targets. This undermines the financial basis for that decision – an eventuality that no mine can afford.”

The end-customer and the project houses, therefore, had to have full confidence in Kwatani’s capacity.

With growing demand from a buoyant mining sector, the company recently added another 3,000 sq.m to its existing 17,000 sq.m facility in Spartan, Johannesburg. Its design and manufacturing capabilities are ISO 9001:2015 certified, ensuring that the latest order to Asia will comply with the highest global standards, he says.

“We also pride ourselves on the quality and resilience of our supply chain, which underpins our ability to manufacture to demanding deadlines,” Schoepflin says. “We carefully select our supply partners – most of whom are local enterprises – and collaborate closely with them to build their sustainability and responsiveness.”

To keep the project’s schedule on track, dedicated in-house project managers and procurement specialists meet regularly with supply partners to ensure a smooth and streamlined process. This has required alignment of all local and global procurement, including motors, drives and steel. The company’s agility allowed contracts and prices to be tied down for timeous delivery, despite the global supply chain disruption that lingers from the COVID-19 lockdowns, Kwatani says.

Kwatani will conduct training of the mine staff in maintenance and troubleshooting, so that they can fulfil these essential duties independently. The mine will be able to source all the necessary spares from Kwatani, who will also send an engineer or technician to site to supervise and sign off on certain major tasks.

Meeting delivery deadlines and avoiding penalties will require detailed logistical planning for the completed units, Schoepflin notes. The screens will be delivered in batches to a South African port, and shipped as break bulk due to their size. Production of the screens is expected to be complete by early 2023.

Kwatani adds to Northern Cape iron ore reference list with latest screening installation

South Africa-based vibrating screen and feeder specialist Kwatani will soon add another installation to its extensive footprint in the Northern Cape, this time for a new customer in the iron ore mining segment.

“We have over 1,000 screens, grizzlies and feeders in this important mining region, giving us a market share of about 95% of heavy-duty screening applications there,” Jan Schoepflin, Kwatani’s General Manager: Sales and Service, said. “With our well-established branch in Kathu, we are also able to assure our new customer of quick and highly competent service levels.”

The ore characteristics of iron ore demands mechanically robust screening equipment and Kwatani has built a name for itself in these applications, according to metallurgist Frengelina Mabotja, Kwatani’s, Head of Sales for SADC. “Our equipment is engineered for tonnage and continuous throughput, without compromising efficiencies,” Mabotja said.

Kwatani’s scope of work on the 700 t/h dry processing plant includes a 1.5-m-wide grizzly screen to remove fines from the run-of-mine material before it reports to secondary crushing and a 1.5-m-single deck scalping screen. The company will also install two 2.4-m-wide, double-deck sizing screens to separate material after secondary crushing, and five feeders to draw material from bins and stockpiles onto conveyor belts for feeding onto the downstream process.

“Our niche expertise allowed us to, once again, offer high performance sizing screens customised for this unique dry sizing application and optimise material separation by achieving the required cut size for the customer’s desired product size,” Mabotja said. “Our solution optimises the material separation while maximising efficiency and ensuring mechanical reliability for continuous and economical production.”

She highlights the depth of in-house experience – from both a metallurgical and mechanical approach– which allows Kwatani to assist the decision making of customers on equipment choice and specifications.

“Through the work of our design team, supported by our manufacturing and testing facilities, we have ensured that the solution will be fit for purpose and reliable,” she said. “The customer was also able to visit our 17,000 sq.m local manufacturing operation in Kempton Park regularly to see how we work, to check on fabrication progress and to witness the testing process.”

The equipment was completed on a tight deadline of 8-12 weeks, for delivery by year-end in line with the customer’s timeframe, according to the company.

“Our fully-equipped branch in the Northern Cape, staffed by specialists with decades of mining experience, will oversee the installation and commissioning of the equipment,” Mabotja said. “Our team will also schedule regular site visits to monitor on the equipment’s performance and condition, and advise on maintenance requirements.”

To underpin the reliable operation of all equipment supplied, Kwatani will also provide training for the customer’s maintenance personnel in the basic maintenance routines required.

Kwatani became a part of Sandvik Rock Processing Solutions late last year.

Kwatani branching out from South Africa roots

Vibrating screen and feeder specialist Kwatani says it is transitioning from equipment supplier to solutions provider, as it attracts customers from well beyond its South Africa headquarters.

According to Kwatani General Manager Sales and Service, Jan Schoepflin, the company’s strong in-house expertise and design capability – combined with the manufacturing quality it consistently achieves – ensures its customised solutions deliver optimal performance at the lowest possible lifecycle costs.

“Our recent orders show that our customer base in Southern Africa remains strong, while there is growing recognition of our cost-effective offerings in West Africa, East Africa and North Africa,” says Schoepflin. “At the same time, orders from countries like Canada and Russia indicate that our markets abroad continue to grow.”

Kwatani says it remains the market leader in the supply and servicing of vibrating screens and feeders on iron ore and manganese mines in South Africa’s Northern Cape province. It also counts platinum, coal, diamond and gold mines in its customer base. Its West Africa orders have been mainly to gold mines, and there is growing potential for gold mining in East Africa, Schoepflin says.

Over its four decades of operation, Kwatani has produced about 16,000 custom-designed screens, and is building, on average, 30 to 40 units a month in its ISO 9001:2015 certified facility close to OR Tambo International Airport in Johannesburg.

“Our reputation has been built on prioritising what our customers need, and doing business with integrity and trust,” Schoepflin says. “This means delivering on what we promise and making sure that customers achieve the expected value from our products.”

The company’s solution focus is underpinned by its significant and ongoing investment in local skills, ensuring that its designs leverage strong mechanical and metallurgical engineering expertise, according to Schoepflin.

“This confidence in our products allows us to offer a process guarantee to customers, to deliver the tonnage, throughput and fractions that they expect,” he says. “Depending on which country our customers operate in, they may also have different industry and quality standards/certification expectations and we work closely with them to understand these clearly and meet their requirements.”

Schoepflin also emphasises the company’s service capabilities, which include its local service centres closer to customers, and its support partners in other countries.

“The careful selection of these partners is vital to meet customers’ stringent technical expectations,” Schoepflin says. “In some countries, our partners can also manufacture components according to our drawings and specifications, should there be an urgent requirement from a customer.”
