A Word from the CMA
The Conveyor Manufacturers Association invests in research projects solely to make information available to industry. There is always the desire to innovate and improve, discover previously unknown facts and then try out these findings so that the results can be shared with the bulk materials handling industry. A panel comprising experts from member companies, academia and end-users supervises and mentors post-graduates engaged in this research.

Order for a mine conveyor system
Metso Outotec has received an order for a heavy-duty mine conveyor system in South America. The delivery consists of high reliability overland conveyors, including a 2km single flight conveyor. Equipment provided in this package runs at speeds of up to 6m/s with a delivery capacity of over 9 000 t/h. The order value is approximately EUR 10 million and it has been booked in Minerals’ Q1/2021 orders received.
Multi-mission Inshore Patrol Vessel
Mammoet has been contracted by Damen Shipyards Cape Town (DSCT) to assist with the launch of the first of three Multi-Mission Inshore Patrol Vessels (MMIPV). Procured by Armscor for the South African Navy, the vessels will augment South Africa’s maritime security to counter threats such as illegal trafficking and fishing.
Preventing Roll Back Incidents
“The Mine Health and Safety Act states that the installation of incline conveyor belts must include the fitting and use of one or more devices to prevent run-back or run-on, to prevent injury by materials or minerals falling from a conveyor belt,” says Carlo Beukes, Business Unit Manager for BMG’s Power Transmission division.
“Tsubaki back stop cam clutches, which prevent reverse rotation of drive shafts, offer a simple and cost-effective means to protect capital equipment and enhance safety on site. This range is available with different capacities and designs, to provide optimal functional characteristics for three basic modes of operation: over-running, indexing and backstopping.
Super-span Maintenance Crane
Condra has followed deliveries of customised cranes for injection-moulding and shipboard maintenance applications with a third overhead machine of unusual design, this one sporting an exceptionally wide span of no less than 35 metres.
A span of this magnitude is more than double the average of fifteen metres, and approaches the manufacturer’s record of 42 metres.
Upgrading of Tippler Project
Bauer Geared Motors, a business division of Hudaco Trading (Pty) Ltd. Co, is delivering a total drive solution that includes five large-sized 750kW industrial gearboxes and two 185kW units for the tippler upgrade project at the Saldanha Iron Ore Export Plant.
Weighing up to 15 tonnes each, the 750kW gearboxes are the largest machines ever supplied by Bauer to date. The company joined the Hudaco group in 2002 and, in the same year, became a supplier to Saldanha providing slew and bucket wheel drives. Bauer upgraded these drives after ten years of operation and in 2020 supplied a third slew drive with planetary gearboxes, and an overland conveyor.
Belt Cleaner Tensioner
Martin Engineering has introduced an autonomous tensioning system that continuously monitors and delivers proper cleaner tension. By utilising an intuitive new smart technology platform to maintain proper blade-to-belt pressure, the N2 Twist tensioner provides the best possible cleaning performance throughout the life of the blade. The system also alerts operators on the Martin Smart Device Manager App when the blade needs changing or if there is an abnormal condition. The result is efficient cleaning, increased safety, reduced labour and a lower cost of operation.
A Proactive Step
Zest WEG phased in IE4 super-premium efficiency motors in its WEG W22 range last month at no premium on the IE3 units. According to Fanie Steyn, electric motors manager, 2021 will see local energy prices rising above R1/kWh for the first time. This makes it the ideal time for the introduction of WEG IE4-rated motors, which are available in the size range between 37kW and 375kW.
“Unlike many countries around the world, South Africa has not regulated the use of energy efficient motors at the level of IE2 or IE3,” says Fanie. “Nonetheless, we have taken the proactive step of making the IE4 level of efficiency available to customers.”
New Spiller for Sugarcane
Bosch Holdings has been appointed consulting engineers for the design and project management of a new cane transloading station in Mkuze, after the completion of a feasibility study. The new facility will assist small-scale sugarcane farmers in the Makhathini region, on the North Coast of KZN.
The new rail side facility incorporates the design and installation of advanced equipment, including a new spiller, that is capable of offloading road vehicles at a rate of over 300 tons per hour, over a 24-hour period.
Simplified Lifting System
Material handling specialists, BLT World, has launched the new Mobicon 2HL series mini straddle carriers in Africa. These are designed for lifting containers securely onto and off trucks and for moving loads around sites, to significantly reduce onsite congestion, making the yard a safer workplace.
Thickeners Double Mine Output
When one of the world’s largest copper and cobalt producers wanted to double its production rates, it chose FLSmidth to provide a thickener solution that included six of its proven high density thickeners. The order was placed in 2020, and delivery has been completed.
The mine, located in the Democratic Republic of Congo (DRC), already had FLSmidth thickeners on site, and was satisfied with their performance. According to FLSmidth general manager projects and account sales Howard Areington, the company’s proposal for the mine’s expanded requirements was based on testwork to confirm the characteristics of the material that would be treated.
