Haver Southern Africa, part of the global screening, washing and pelletising equipment and system design and manufacturing specialist Haver, recently entered the Southern African market as a processing solutions provider and partner, and will be exhibiting its processing technologies at Electra Mining 2012.
“It is common knowledge that global resources are dwindling – mines are delving deeper to find deposits and volumes have to be increased to achieve the same output due to decreasing grade quality,” says Joachim Hoppe, Haver Southern Africa operations manager. “As a result of more extreme mining and mineral processing, customers are demanding higher capacities from their equipment. Productivity remains any mine or plant’s number one priority, and they simply cannot afford failures and unplanned downtime.
“We have noted a marked increase in the demand for large vibrating screens and our wide range, including 4-bearing, 2-bearing, linear and eccentric-driven screens, operate reliably and perform efficiently and optimally, with little maintenance required under even the most stringent conditions. They are tailor-made to meet customers’ individual processing requirements. From gold, copper and iron ore to oil sand, our rugged screening machines are engineered and manufactured to handle widely varying or irregular input material feed rates, varying particle sizes – from fine to very course material, as well as difficult-to-screen material such as moist, sticky and/or very dirty materials”, he explains, adding that the screens are also ideal for limestone and hard rock processing, gravel screening and building rubble recycling.
According to Hoppe, short lead times are just as important to customers as reliable and efficient performance. “We draw from the global resources and strength of the Haver Screening Group, which consists of three manufacturing facilities based in Brazil, Canada and Germany. Our designs are modular, manufacture is spread between these three workshops and assembly is completed in the closest location to the plant, a successful recipe for short lead times.”
Few companies have the capacity to design vibrating screens of the size required on processing plants today. “The largest vibrating screens we have designed and manufactured have a 20 000 tph capacity, handling oil sand at a Canadian plant.”
Hoppe says that it is so much more than just selling machines. “Our advisory service right at the beginning of a project is as important as our maintenance or refurbishment services. We always look for the best and most affordable option for our customers; we can sometimes refurbish for 30 to 40% of the cost of a new machine.”
