ON THE COVER

ModernQuarrying OctNov 2017Sandvik Mining and Rock Technology recently supplied, installed and commissioned a CS440 secondary stage crusher at Afrimat’s Lyttelton Dolomite operation in Centurion. Selected for its size, the unit is pushing out product at an impressive rate. Formerly known as the S4800 cone crusher, the new unit is characterised by its large intake capability and high throughput in relation to size. Weighing in at 19,3 t with a maximum power of 220 kW, it is a large machine and it is not often that a quarry takes a crusher of this size.

In this issue

Mining solutions provider sets the benchmark

In the October-November issue we lead with a visit to SPK Kundalila’s Kersfontein Sand mine in Kalbaskraal, Malmesbury. A relatively small mine at this point in time, it is manager Jean Martin’s aim to bring it from infancy into adulthood in a sustainable and environmentally-friendly manner.

Quality dolerite no problem for Howards Quarry

Our second lead looks at the high quality dolerite aggregate from B&E International’s Howards Quarry at eMalahleni, which is keeping Much Asphalt’s nearby static plant well stoked to produce asphalt for the N4 highway project and other developments as far as Nelspruit over 200 km east.

Aspasa substantially broadens membership umbrella

MQ’s third lead is a face to face chat with Aspasa director Nico Pienaar. We look at the reasons behind the substantial increase in the Association’s membership base and how it sees it role in the future. We discuss the key focus areas and how Aspasa is assisting the industry with training.

Conveyor belt safety in the 21st century

The technical paper by Jaco Swartz, Legislative Compliance Specialists (Pty) Ltd, was first presented at the recent Beltcon 19 conference. Published in two parts – the first of which is in this issue – the paper aims to illustrate the development of legal rules within the mining industry and to address the risks posed by conveyor belt installations. As such it focuses on the historical need for rules dealing with workplace risks.

The regular Industry Report looks at new opportunities for junior miners; next year’s Hillhead exhibition; a Bell deal with Lonagro; successful mine closure; a sampling award for a Wits stalwart; and skills development for the disabled.

MQ’s supplier spotlight features the New heavy tipper from Scania designed to reduce quarry haulage costs; and the regular Market Place highlights GEM’s new product offering; a FLSmidth piece on rock intrusions, which are a problem in terms of sizers and breakers; MDS trommel screens; the massive Komatsu wheel loader destined for Zambia; HPE’s new 20 t crawler excavator; Burma Plant hire – which has substantially expanded its fleet; and Osborn, which is responding to the skills deficit industry is experiencing.

And finally, in Last Blast this month, we publish a historical article going back to 29 September, 1989, when the then Natal Crushers prevented the main arterial road between Durban and Johannesburg being severed due to widespread rain across the region.
