OSBORN INNOVATION MAKES JAW CRUSHER LINER LIFTING SAFER AND MORE EFFICIENT

Image
Reflecting its commitment to working with customers to continuously improve its products and services, mining equipment specialist Osborn has developed an innovative enhancement to its jaw crushers. This improvement will make the leading manufacturer’s tough, high-quality machines safer and more efficient than ever, according to product development manager Andre van Tonder. “When our customers asked us to investigate alternative ways to lift jaw crusher liners in and out of our machines, we listened and responded. After detailed investigations, and having conducted on-site tests with customers, we are rolling out liner lifting features that cater for specific customer requirements,” he explains. Osborn’s designs use standard lifting equipment, not special lifting tools, and have been thoroughly evaluated on several mines and quarries. This innovation will deliver exceptional benefits to customers. Van Tonder elaborates: “With Osborn’s new jaw crusher liner lifting points, there is...

Contributing comfort to help ease harsh learning conditions

Image
Education is at the top of the agenda for our country and the responsibility of ensuring quality education should not only rest on the shoulders of the South African government. There are many barriers to education in the country, such as malnutrition, poor school facilities and access to learning materials, to name but a few. AEL Mining Services, a leading supplier and manufacturer of explosives, has embarked on a campaign that will look to remedy one such barrier: the lack of a proper school uniform. Thabo Nkoane, Executive: Human Capital at AEL Mining Services says, “One of the many issues we have seen in the areas in which we operate, is that children walk long distances to school, and normally they are barefoot. AEL is a responsible corporate citizen, committed to the sustainability of the communities in which we operate. With this in mind, we are contributing to the ‘Bare Foot No More’ initiative, which has developed a unique school shoe for children especially in rural area...

South Africa’s finest young scientists to compete in world’s largest international pre-college science competition

New grease filling filter for automatic lubrication systems

Image
SKF announced the introduction of its Lincoln small grease reservoir filling filter. Part of SKF’s family of filtration products, this filter helps to minimise contaminants entering automatic lubrication systems during the filling process of smaller-sized reservoirs. Installed as an inline component in the reservoir’s fill line, the filling filter helps to ensure that clean grease enters the reservoir and the system. As grease enters through the inlet, it passes through the filter and then exits into a hose that is connected to the grease reservoir’s fill port. As the filter element becomes clogged, the unit’s clogged-indicator pin starts to retract, signaling that filter element cleaning is required. If the clogged filter element is not cleaned, grease will vent safely to a catch container but will not bypass to the reservoir. The easy-to-install Lincoln small grease reservoir filling filter is available with either a 250- or 500-micron, crush-proof filter element, which is simp...

SKF Explorer tapered roller thrust bearings: optimised for the most demanding oil & gas applications

Image
Advanced bearing design offers higher load rating and up to 300 percent longer rating life The oil and gas industry continues to push the limits of technology. Deeper wells, harsher environments and more sophisticated drilling approaches all place additional demands on equipment, calling for larger, more powerful and more robust solutions. Top drives, which power the drilling process, are right at the front line of that technological race, and when unplanned downtime can cost operators $1 million a day, performance and reliability are critical attributes. To meet the demands of leading top drive manufacturers, SKF has developed a new generation of tapered roller thrust bearings, the first to join its Explorer family of high-performance bearing products. With higher load ratings and bearing rating life extended by up to 300 percent, the SKF Explorer tapered roller thrust bearings are ready for the next generation of larger, more powerful top drives. They can also be used to optimis...

Centre of pressure

Image
The development of a range of class-leading hydraulic piston seals required SKF engineers to create tailor-made materials and apply advanced analytical techniques. The piston seal lies right at the heart of hydraulic cylinder performance. Located in a groove on the outer diameter of the piston, this seal must contain the high pressure hydraulic fluid without impeding the motion of piston along the length of the cylinder. Since most hydraulic cylinders operate bi-directionally, the seal must be able to handle pressure from either side. The design of piston seals requires engineers to tread a fine line between friction and sealing performance. If the seal allows too much fluid to leak from the high pressure side of the cylinder to the low pressure side, performance is compromised. On the other hand, excessive friction on the cylinder wall leads to accelerated wear and a reduced operating life. Outright failure of a piston seal, known as blow-by, can have significant operational and sa...

LONMIN LAUNCHES GRIEVANCE SYSTEM FOR THE GREATER LONMIN COMMUNITY

Wednesday 25 April Lonmin is proud to announce the introduction of a community grievance mechanism – a mechanism which has received input from all affected stakeholders over many months of planning and research and constitutes, what the company believes, is best practice. The mechanism known as Buang Le Rona/Thetha Nathi – meaning ‘Talk to Us’ in English – kicked off last year with a pilot project and EVP: Stakeholder Engagement and Regulatory Affairs, Thandeka Ncube expressed her excitement to be launching a full-service grievance system. The aim of the system is to improve two-way communication and the resolution of grievance within the Greater Lonmin communities. “The system came about as a result of the introduction of an internal policy based on global best practice and international principles offering our communities” explained Ncube. “We made it a point to ensure that grievances and conflicts are mediated in a transparent and fair manner, and most importantly, this system w...

World investors look to Zimbabwe

Infrastructure stakeholders from around the world are showing keen interest in Zimbabwe as a new spirit of optimism takes root in the country. South African business, with its tendency to ‘wait and see’, could miss the boat in terms of opportunities in Zimbabwe, while international investors flock to Zimbabwe to explore new business potential there. This is according to Duncan Bonnett, Director Strategy & Business Development at research and consulting specialists Africa House, who has led two fact-finding and business development delegations to Zimbabwe in recent months. “The prevailing spirit in Zimbabwe has changed dramatically over the past years,” says Bonnett. “Zimbabwe’s public and private sectors are more positive than they have been in possibly 15 years, but with a sense of realism. Significant infrastructure and industrial revitalisation projects are planned, but there are still certain challenges in the way of realising them.” As managers of the pan-African VIP ...
