DoppiaTrac DR400 delivers the tonnes for industry entrant gle pass. This means that there is no need for additional screening and a return con- veyor to pass oversize material back to the crusher. Apart from removing the capital or hire costs for these pieces of equipment, there are also considerable savings in run- ning costs, especially diesel.”

tors not only for the efficiencies it offers in a highly competitive business but also for its unique status in the local market as a track-mounted double roll crusher. The first DoppiaTrac DR400 to be deliv- ered in 2016 was supplied to Witbank plant rental business Spy Imports and Hire in January. The year began with an urgent contract to process run of mine (ROM) ther- mal coal from >80 mm spec to <40 mm spec. Pilot Crushtec International was able to respond to the customer’s needs by sup- plying a brand new product ex-stock and, within a matter of days, the machine had been delivered, commissioned and was producing product in line with, if not bet- ter, than customer expectations. Pilot Crushtec International CEO Sandro Scherf explains that the DoppiaTrac’s acceptance in themarketplace is verymuch related to the economies and efficiencies it delivers to owners and contractors. “In thermal coal applications, the DoppiaTrac DR400 can crush >80 mm ROM coal down to <40mm specification in a sin-

Another benefit is that the DoppiaTrac is noted for delivering product with a low fines content, a major bonus when pro- cessing coal and similar materials. Spy Imports and Hire owner Martin Brown is well pleased with his company’s new acquisition.“The tonnages are as good aswe expected, averagingbetween 300 and 350 tonnes per hour (tph) and occasionally approaching a rate of 400 tph,”he says. Brown first made contact with Pilot Crushtec International in 2015 via the company’s website which indicated that it is currently the sole local supplier of a tracked double roll crusher – a product that he identified as being most suited to his needs.

We can ref- erence a number of enduring heavy duty vibrating screen installations in the iron ore sector, including ones in the South African Northern Cape, that have been in operation for more than 40 years,” says Johannes Kottmann, Managing Director of MBE Minerals SA. The 2,4 by 4,5 m screen employs the principle of resonance and dynamic vibra- tion absorption for its screening action. “A number of design elements have been incorporated to enhance performance, including the operation of the screen box at near resonance frequency. This allows the actuating device to replace only energy lost to the oscillating system by mechanical resistance and material trans- port,” Kottmann explains. A counter-oscillating frame of pre- determined mass ratio to the screen provides vibration absorption, thus mini- mising the transfer of dynamic loads into the supporting plant structure.

Coal supply for a variety of end users remains a hot topic in the South African mining industry and process operators are continually looking for cost-effective solu- tions to provide in-spec product against a background of deflated commodity prices. One such solution is the DoppiaTrac DR400 double roll crusher designed and built by Jet Park crushing and screening specialist Pilot Crushtec International. The product is establishing itself as the coal crusher of choice with coalfield contrac- The DoppiaTrac is a track mounted, self-driven, feeding, crushing and stockpiling machine for medium to hard bituminous coal crushing applications.

The recent supply of a complete resonance screen with an additional screen box to an Australian iron ore mine underpins MBE Minerals SA’s drive to participate in global markets. The supply of these screens by MBE is the continuation of the screen replace- ment programme of 20 such machines for this major Australian iron ore producer. “Significantly, the original screens were manufactured in South Africa by MBE Minerals in 1997 and have been operating MBE Minerals makes inroads into Australian market

Reelcare sets up shop in South Africa Major UK hose and cable reel supplier Reelcare Ltd has established an operation based in South Africa. It has set up its hose and cable reel business in a fully stocked warehouse facility located in Wadeville, Johannesburg. Reelcare, which currently distributes hose and cable reeling equip- ment in the UK through its own network of distributors and OEMs, holds many agencies from globally respected hose reel manufac- turers and plans to replicate its UK business model in South Africa.

developed some extremely good business relationships within these market sec- tors. However, we also recognise that even though the mining industry in South Africa is a major consumers of hose reels, there are many other industries in South Africa with whom we have experience from our UK operation. Since our product ranges overlap in most industrial sectors, our South African operation will be the focus of our targeted approach to the South African market giv- ing us the opportunity to grow.” Whilst there are companies in South Africa which sell small ranges of hose reels, Reelcare has a comprehensive range of hose and cable reels and describes itself as a “one-stop shop”for all reeling requirements.

“This venture was not a difficult decision to make,” says Terry Crabtree, Sales Director of Reelcare. “We already enjoy doing busi- ness in South Africa within the mining and lubrication industries and have done so for many years. Over that time we have
