This bimonthly issue of MechChem Africa features Valves and Automation and its Zwick TRI-SHARK Throttling Trim Cartridge valve on the front cover. As described in the cover story, this valve combines the advantages of a leak-free triple-offset valve (TOV) with a high-performance control valve.

Minerals processing and materials handling features articles from: Tenova company, TAKRAF about a conveyor for a large copper mine; Weba Chute Systems about the complexity of chute design; B&E International about its build-operate-transfer (BOT) financing model; Kwatani about achieving low TCOs of sizing screens; and from Multotec about a sievebend test success.

Power transmission, bearings, bushes and seals features a comprehensive article from BMG about the differences between the bearing types in its range. This is followed by a piece from SEW-EURODRIVE about agitator drive solutions; ABB, which has installed a new ring geared mill drive; and a product article about VSD solutions from BI.

Hydraulic and pneumatic systems opens with an article about Hytec Fluid Technologies’ Accumulator testing, refurbishment and recertification service and also includes an article about portable Enerpac E-pulse pumps from BMG.

Automation, process control, instrumentation and CAE features Altair’s 2020 software release, mooted to be the most significant in the company’s history; and articles from Endress+Hauser; FICO; and Rockwell Automation, while the Energy feature for this issue comes from renewable energy champion, Aurecon, which is now called Zutari.

In the Environmental management, waste and cleaning technologies feature, Safripol and PETCO celebrate a first of its kind recycling project in Limpopo; and Process engineer, Phola Kula, talks about the science of her dream job at Biodx.

Completing the issue’s features is Innovative engineering, which reports on an analysis by Lux Research of how future global energy networks will evolve while moving away from the use of carbon-based fuels.
