A leading supplier of mobile and semi-mobile crushing, screening and materials handling products – South African-based Pilot Crushtec – has cornered the silica mining market in South Africa. This is the claim by sales manager Graham Kleinhans, who says there are currently more than ten Twister vertical shaft impact crushers in operation at silica mines in the country.
IMS Engineering (IMS) is in a joint venture with its comminution technology partner, EarthTechnica Company Limited (ETCL) of Japan – manufacturers of the EarthTechnica Kawasaki KG 5525 HD-S primary gyratory crusher, which is to be installed near the Foskor south pit by July 2009.
Foskor currently processes pyroxenite from the north and south pits and reclaims foskorite from depleting surface stockpiles, all of which contain phosphate. The phosphate rock is used to produce phosphoric acid, which, in turn, is used in a number of applications including fertilisers, animal feed and food preservatives.
