Weir Minerals has delivered a custom designed plant that has boosted production and increased the product range at a sand and aggregates miner in Iowa, US.

Family-owned Pattison Sand produces a diverse range of products, servicing several industries including infrastructure and construction.

Weir said: “After successfully using a number of Weir Minerals products at their site, Pattison Sand wanted a custom designed plant capable of producing more than seven materials: concrete stone, road rock and base material, asphalt stone, asphalt chips, railroad ballast and manufactured sand. This was a challenging demand considering most aggregates sites in the region typically focus on producing only a few products.”

Eric Jones, Global Service Director of Comminution Aftermarket for Weir Minerals, said when Pattison Sand presented the plan for their sand plant, the company’s integrated solutions team “worked with them to make it a reality”.

The facility, comprising both an underground and open-pit mine, is located on the Mississippi River. It processes highly abrasive materials and, combined with the physical diversity of the site, presented a number of technical and engineering challenges to Weir. On top of this, the company had three months to deliver and commission the plant.

Chance Harvey, Director of Engineering at Pattison Sand, said: “We develop these solutions with Weir Minerals through a lot of trials, successes and failures, and end up getting the results that we need to continue to survive in the marketplace.

“A lot of the options that other equipment manufacturers supply are standard and by the book. Weir Minerals has the ability to work with us to create solutions for our individual issues.”

The site has a unique rail loadout setup where product is dispatched to customers as soon as gradation and quality data is approved. This meant Pattison Sand needed an efficient, dependable plant to meet stringent delivery requirements.

Weir Minerals supplied a number of products to create two primary and secondary crushing stations at the operation. These included a Trio® TF5220 vibrating grizzly feeder, two Trio EF3603 pan feeders and two Trio TP450 cone crushers. Trio scalping, incline and wet incline screens, as well as a Trio TSW4432 fine material washer, were also supplied.

Full training and support was provided, with Weir Minerals regularly on site to help Pattison Sand optimise their entire process and achieve the desired result, Weir said.

It continued: “The flexibility of the custom built plant has allowed Pattison Sand to operate more efficiently, exceed production target and increase their product range.”

Since commissioning the plant, Pattison Sand has been able to produce 500-800 t/H of high-quality aggregate material, which equates to around 2.5 Mt/y of raw product. Four hoppers provide a loadout rate of 500 t/h enabling Pattison Sand to produce a diverse range of products and still meet demanding customer delivery schedules, Weir said.

Jones said: “When customers purchase Trio products they are buying years of experience from people within an organisation that is dedicated to the industry and its customers. We constantly strive to be closer to our customers. It’s not always perfect, but we work through projects together and are honest with each other. It’s that transparency and working with customers like Pattison Sand which really drives the end solution.”

NRW Holdings signs A$10 million deal to buy RCR’s Mining and Heat Treatment businesses

NRW Holdings has entered into an agreement to acquire RCR Tomlinson’s Mining and Heat Treatment businesses for A$10 million ($7.3 million) in cash.

The agreement was signed with RCR’s administrators, which have been offloading various RCR subsidiaries since shortly after the company declared total liabilities of A$581.3 million alongside cash and equivalents of A$89.9 million in its 2018 financial year.

The purchase consideration will be funded from NRW’s existing cash reserves, with the deal expected to complete within the next two weeks, NRW said.

RCR Mining and Heat Treatment form part of the original RCR Tomlinson business established over 100 years ago.

RCR Mining includes the Mining Technologies business, which owns significant intellectual property across a range of products and processes and is recognised as a market leader by global resources clients, according to NRW.

“The Mining Technologies business is a leading national and international original equipment manufacturer and innovative materials handling designer with an extensive product range including apron and belt feeders, high capacity conveyors, slide gates, stackers, spreaders, fully track-mounted in-pit mining units (an example pictured above), sizers, scrubbers and screening plants,” NRW said.

One of RCR’s recent mining technology innovations is a 5 km relocatable conveyor, which includes a semi-mobile primary crushing station and feeds directly into Fortescue Metals’ Cloudbreak iron ore processing facility in the Pilbara of Western Australia.

Both the Mining Technologies and Heat treatment businesses have a high proportion of activity in equipment product support and maintenance (both on site and off site), NRW said, adding that the Heat Treatment business has facilities that include the largest stress relieving furnace in Australia.

Mining Technologies and Heat Treatment generated around A$110 million of revenue in the 2018 financial year and have a track record of delivering positive earnings, NRW noted, explaining the acquisition would be earnings per share accretive on a full-year basis, excluding integration and other one-off costs.

Jules Pemberton, NRW’s Managing Director and Chief Executive Officer, said the acquisition would allow NRW to provide incremental services, in line with its strategic objectives, to several core clients common to both NRW and the RCR businesses.

“In addition, the annuity style income from the maintenance activities of Mining Technologies and Heat Treatment will provide a platform to continue to build a broader service offering across an expanded resources and oil and gas client base.”

Kwatani registers global mining demand for vibrating equipment

Kwatani’s vibrating screens and feeders are continuing to find a market in the mining industry, with a number of orders recently secured from diamond, coal, zinc and platinum operations.

The company’s custom engineered products are now in some of the world’s largest mines, and many customers have standardised on their screens to ensure lowest cost of ownership and high performance, according to General Manager, Sales and Service, Jan Schoepflin.

“While our base and core market are in Africa, the global demand for Kwatani products has grown rapidly. A leading diamond mining company in Russia is very pleased with Kwatani screens at their newest operation and specified Kwatani for future projects,” Schoepflin says.

In another order from a large diamond operation, this time in South Africa, the customer replaced the last of its competitor screens with a Kwatani unit. Schoepflin says this is because it has enjoyed years without unplanned stoppages by using Kwatani screens.

At a local brownfield diamond expansion project, the company’s multi-slope banana screens were matched to the available plant footprint, raising throughput from 250 t/h to 500 t/h and, later, breaking the mine’s tonnage record.

“While screening in heavy minerals is Kwatani’s stronghold, the company has moved extensively into coal, supplying the country’s (South Africa’s) leading coal producer with no fewer than 45 items of large screening equipment, including out-sized 4.3-m-wide units,” the company said.

Other recent coal-related orders included run-of-mine screens for a medium-sized coal mine in Mpumalanga, South Africa. Again, competitor equipment was replaced by custom designed screens with optimised deck angles, which significantly increased tonnage, according to the company.

“The positive results achieved with the Kwatani equipment also led to additional orders for the mine’s expansion,” Kwatani said.

For world largest zinc mine, Kwatani was contracted to supply all the screens, while, at Africa’s largest iron ore mine, the company recently completed two projects, renewing existing equipment with updated solutions and replacing 24 items of competitor equipment.

“The platinum sector is also keeping Kwatani busy, not just in South Africa but over the border in Zimbabwe too,” Kwatani says. A recent turnkey solution focused on platinum by-product chromite, where the company supplied a complete solution which included feeder, dryer and screen to treat chromite of 45 micron size at 15 t/h.

Schoepflin said: “Our screens have been a popular choice for modular gold plants going to West Africa as well as Central and South America. We also supplied to two of Africa’s largest copper producers in Zambia, to a tanzanite producer in Tanzania, and repeat orders to a manganese mine in Ghana.”
