Modern Quarrying Q4 2019

Following a collaborative design process with Ground Breakers, CDE developed and built a Combo modular plant to transform 60 tonnes per hour of raw feed into washed 0-6 mm river sand and 0-1,5 mm plaster sand.

AT THE QUARRY FACE

BREAKING NEW GROUND

H aving started producing sand and aggregates out of decomposed granite back in November 2016, Ground Breakers – a brainchild of two young entrepreneurs with a background in plant hire, logistics and quarrying industries – is fast becoming a sand producer of choice within its area of supply. Within three years of operation, Ground Breakers – owned by Johan Meintjes and JC Janse van Vuuren – has established itself as a leading supplier of construction materials. Operating from its Lindley quarry in Johannesburg, the company produces an array of construction materials, including G5, G6, G7, building sand, river sand and plaster sand. At the centre of its market leading position is the quality of its sand and the flexibility to produce to customer spec. Key to these capabilities is the recent investment in CDE’s patented Combo™ – the world’s first all-in-one wet processing plant. Before investing in the CDE Combo, Ground Breakers previously deployed a bucket wheel system to transform the quarry’s raw feed of decomposed granite into construction sand and aggregates, with additional low-value fill or bedding products. The downside Bucket wheel systems have traditionally been the mainstay for washing sand in the local market. These were cheap to buy,

By tripling production, enabling production of two sands simultaneously and significantly reducing water usage, among other benefits, CDE’s cyclone technology is paying huge dividends for a South African sand and aggregate producer. By Munesu Shoko .
