Carmix South Africa
supplied a Carmix 3.5TT
to Wepex Construction operating on the Orapa Diamond Mine, Botswana.
The Orapa Diamond Mine, located in central Botswana 240km west of Francistown, is the worlds’ largest open pit diamond mine producing an average of 12 million carats of diamonds per year. The mine currently operates at a depth of 240m, however it is predicted to reach 450m within the next 10 years. In order to reach such depths specific methods must be implemented to support the pit walls and prevent deadly landslides or rockfalls, which is where Wepex is functioning.
Wepex is a geotechnical contractor specialising in rockfall mitigation, soil and rock stabilization, piling, specialised grouting and trenchless crossing. Wepex is using the Carmix to produce 35mpa shotcrete that will support the walls of the pit in conjunction with lateral support provided by self-drilling anchors. This highly specialised application requires good quality shotcrete to be produced with consistent slump and strength.
The 5 day commissioning was done on site in Botswana by two Carmix South Africa
representatives who trained a number of Wepex staff, including operators and mechanics, in the operation and maintenance associated with the Carmix 3.5TT. During training particular attention was payed to the Carmix Winscale system which is essential to ensuring the consistent quality of shotcrete is met.
The Carmix South Africa team wish Wepex a successful project at Orapa using the Carmix 3.5TT.

CARMIX BUILDS A CHICKEN FEED Carmix recently help build a Poultry feed mill at a well-known chicken farm in Lichtenburg. There were some challenges faced, one of the biggest was contending with the rainy season that had just started in Lichtenburg competing with deadlines we had to start working longer shifts. Some of the things that helped us were: Adjusting the mix design to one that work to our advantage with all the rain. The Carmix was built for any types of terrain. The cabin on the 3.5TT is closed and equipped with Clima (air conditioner and heater) which kept the operator comfortable and focused allowing him to discharge accurately. Having well trained and professional operators who have done all the necessary training on how to operate the Carmix. Our Carmix 3.5TT did not disappoint, in the 3 months we were on site we mixed about 1000m3 of concrete, our biggest pour was 200m3 in 24 hours. Site set up and having your aggregates close is important for maximum productivity, on this site they had a 15 000kg cement Silo and two 10 000 litre water tanks only 400 meters from the discharge site which did speed up productivity to get the more loads done within the day. Despite having to deal with wet muddy conditions the Carmix 3.5TT pushed through every challenge thrown at it.
