“Initially, our Kal Tire customer base included a number of underground operations, but we were primarily focused on surface mining operations; however, after an acquisition of Tyre Corporation last year, Kal Tire now has about 1 500 people in the Southern African region, of which about 1 060 are currently in South Africa,” Martin explains.

A mining engineer by profession, Martin joined Kal Tire in April 2017, a month before the acquisition was complete – an interesting time in the business, to say the least.

“Although, at the time, I didn’t have a history in the tyre business, I do have a clear understanding of the demands of mining operations, which has been particularly beneficial.

reeling drums; downshop and festooning systems; Mennekes and AMPCO plugs, connectors and sockets; as well as crane accessories will complete the extensive display from Powermite.

Powermite is part of the Hudaco group of companies and is a leading supplier of electrical and mechanical equipment for moving machinery in the Southern African region. The company has been participating at Electra Mining for several years and Rolf Lung, managing director, says that the mining exhibition has always been a good platform to engage with not only the mining sector but also with general industry.

“While past participation has led to new lead generation and business opportunities, the exact measurement of success at any trade exhibition is difficult,” notes Lung.

“However, we no doubt believe that our exposure and presence at Electra Mining contribute towards our Powermite brand awareness in the market. We believe that it creates the ideal platform to meet existing customers, show off new products and developments, as well as secure new enquiries and build new relationships.”

Lung adds that in addition to its exciting new product offerings, Powermite is also giving visitors to its stand (F16: Hall 6) the opportunity to enter a lucky draw competition with great prizes up for grabs.

Powermite will be jointly exhibiting with sister company Proof Engineering, a specialist in the design and manufacture of a wide range of innovative flameproof, explosion-proof and non-flameproof products focused on

“Smartphones have changed all this. They enable instant communication from underground to the surface, from the surface to underground, and from one underground location to another but, at their core, they are tools that can be used for so much more.”

Two hundred frontline employees are equipped with devices that look and work like an ordinary smartphone.

They are, however, intrinsically safe and designed to withstand harsh conditions.

Apart from being able to make voice calls via an app called CSIP Simple, employees can use Cisco Spark to send text messages and photographs. They can send and receive documents like policies, procedures and section plans.

“In the past, foremen would sometimes only get around to reporting a machine fault at the end of a shift; now they can get in touch with the appropriate people on the spot and send an accompanying photograph of the issue,” says Meyer.

Real-time work management and access to live data Work management has also been made more efficient with an app called Fewzion. “Underground personnel are able to view all tasks scheduled for the day on the screen, tick them off once they have been completed and provide status updates on work in progress. At the same time, the supervisor on the surface has an accurate picture of how work is progressing.

The Power BI app provides live data that could previously only be retrieved via the control room. This means that key personnel have round-the-clock access to critical information, which can either prevent or immediately address unnecessary downtime.

steps towards sustainable water management

P

The current global demand for water is around 4 500 billion m³ a year and is expected to rise to 6 900 billion m³ by 2030. With that in mind, it’s imperative that businesses take action to ensure sustainable water management is practised.

implementing an effective water management strategy, which can minimise a mine’s carbon

footprint, save time and improve worker productivity.

Wood shares his top five tips on how your mining business

can sustainably manage water usage.

Do your research

Investment Pumps are among the most expensive components on a mine site and even more costly if they are incorrectly specified and not truly required. Saving money and time are two important factors to consider when it comes to investing in pipes. Therefore, you should investigate whether your intended piping installation could operate

effective solution in the long run.

Understand and evaluate your water wastage Understanding where your water source is coming from and how it is being used is crucial to directing your water management. Start by drawing a schematic diagram that shows inflows, sources of fresh and process water and how it’s recycled. This will allow you to understand the situation and adopt the changes necessary.

Another important step is to understand the cost of water on both a financial and risk basis for current and future conditions. Consider how your operation impacts the environment and whether you could implement alternative methods to optimise water use and save time and money.

Educate employees One way to achieve more streamlined production is to ensure your employees are on the same page. Make sure employees can identify any practices that need to be rectified during your water management solutions process, which will, in turn, also improve productivity.

It’s important that employees are taught about the importance of water management and any processes being implemented that will allow you to do this more effectively.

Understand the benefits For many mining applications, pumped water management systems are a necessity and the associated pipework must be capable of withstanding a specified internal pressure.

However, towards the end of a mine’s water cycle, pressured systems are still being specified when gravity pipes could provide a more economical solution. Understand which piping system is going to provide the best solution

driving the industry forward Providing great quality spring cable reels Powermite, a supplier of equipment for moving machinery, has boosted its cable reeling systems with the introduction of a new SR-Express range from Conductix-Wampfler.

The company, which holds exclusive Southern African distribution rights for Conductix-Wampfler, says, “We understand the importance of product quality for customers and end users because this is fundamental to product reliability, which in turn leads to high machine and plant uptime, productivity and profitability.”

Rolf Lung, MD of Powermite, adds, “It is, therefore, our responsibility to supply products of uncompromising quality that SR-Express spring cable reels from Powermite are IP65 rated to meet the energy and data supply needs of moving machinery

will perform over a long life cycle for lowest total operational and ownership cost.”

The new SR-Express SR10-SR60 range is a selection of spring cable reels from Conductix-Wampfler’s global SR range and is a tailored response to customers’ expectations. Spring cable reels are the culmination of ConductixWampfler’s 100+ years of experience in electrification systems. They demonstrate the company’s expertise in the field of manufacturing energy and data supply solutions for mobile industrial machines.

“Arranged in series or parallel, the springs are manufactured from highperformance textured steel and are lubricated with corrosion-resistant grease and individually encapsulated in a cassette. The patented spring cassette ensures safe and easy manipulation including replacement or reversal of winding direction. “The mounting flange, manufactured from cast aluminium alloy or cast iron, has been specially designed for quick, easy and safe installation of the reel on the spring reel shaft,” he concludes.

Mobility to the power of four Atlas Copco’s Power Technique business unit will display its four-pillared product portfolio that delivers the perfect balance between performance, versatility, reliability, efficiency, and portability at Electra Mining 2018.

“Focused on mobility, our products power customer productivity across a wide spectrum of applications within the mining, construction, drilling and rental sectors,” says David Stanford, business line manager at Power Technique. “The four pillars house air, power, light and flow solutions, with service providing a solid foundation.”

The equipment manufacturer says its Power Technique compressors, generators and light towers have gained tremendous traction in the mining industry, supplying convenient and efficient on-site portable air, power and lighting.

“Building on the success of these three power solutions, we decided to introduce pumps to our product portfolio almost

three years ago, forming our fourth pillar – flow,” explains Stanford. “The addition of flow power, i.e. pumps, was simply a natural progression, perfectly completing our power package.”

The Atlas Copco diesel, petrol and electric mobile dewatering units, comprising openframe PAS dry and VAR wet self-priming centrifugal pumps, are complemented by the renowned Weda range of centrifugal electrical submersible pumps.

“Our pump offering is a little different, setting us apart in the pumps space; we supply a fully imported modular package, making it one of the most flexible and costeffective solutions currently available,” Stanford concludes.

Powerful hand-tool cutting accessories The trading brand of global multichannel distributor Electrocomponents, RS Components, has added a range of Lenox power and hand-tool cutting accessories to its portfolio of products for maintenance engineers.

The new Lenox range includes power tool cutting accessories such as cut-off wheels, reciprocating saw blades, hole saws, jigsaw blades and step drill bits.

“Designed for use in the same power tools as bonded abrasive types, Lenox’s Metalmax diamond technology is offered as an alternative cut-off wheel, operating with the same RPM and feed forces,” says the company.

“The product also offers excellent durability by delivering 1 000 or more cuts – up to 30 times longer life than thinbonded cut-off wheels. In addition, cutting depth remains the same throughout its life, which ensures better control, reach and precision. The technology can cope with multiple types of metal including steel, sheet metal, stainless steel, rebar (reinforcing bar), cast iron, aluminium and other non-ferrous metals.”

A second range available from RS are reciprocating saw blades, which include: LAZER CTÔ carbide-tipped blades, offering up to 10 times longer life than standard bi-metal blades; DEMOLITION CTÔ blades, designed to cut through nails embedded in wood; and GOLDÒ POWER ARC curved blades, which deliver up to two times longer life when compared to traditional straight reciprocating saw blades.

Value-added screening service for coal sector Screening and vibrating equipment provider Aury Africa can advise coal plant operators on the correct screen size to maximise operational efficiency, coupled with comprehensive after-market support to assist with all proactive maintenance requirements.

The company says it is also able to supply a range of exciters to fit most OEM screen types. Consumable products available include intertank/interstage cylinder screens for classification, sieve bends and static panels for separation, and centrifuge baskets.

“The fact that we can access technical expertise from our international group is a major advantage for our customers, as we have extensive experience coupled with expertise, due to having worked with vibrating equipment in the mining industry for many years,” says Sydney Parkhouse, director, Aury Africa. Another major

benefit for local coal mining customers is that Aury Africa can provide bespoke solutions, in addition to having a standard equipment range. “We have an in-house design capability, and can even undertake research and development in order to cater for specific requirements and applications,” Parkhouse notes.

George Sturgeon, business development manager, Aury Africa, adds that while the mechanical principles of vibrating screens are well understood, there are numerous variables that need to be taken into account, especially with diverse applications such as dewatering.

“Vibrating screen aperture sizes need to be calibrated carefully depending on the type of raw coal being processed. This is especially important for coal being supplied to electricity utility Eskom, for example, which has specific quality standards for power-generation purposes.”

Banana vibrating screens are available in single- and double-deck configuration
