THE PRIMARY CONCENTRATOR AND DRYER The ore is automatically dumped from the tramline buckets into the hop- per of the mill’s primary concentrator. Here a series of screens and an impact crusher separate the waste rock which is transported to the tailings pile. The remaining ore, which contains most of the free asbestos fibre, is subjected to further screenings where the “throughs” are efficiently separated from the “overs”. The “throughs” are delivered to two large eighty inch diameter sixty foot long rotary kiln dryers which, by the application of intense heat, reduce the moisture content of the ore ta a maximum of three percent. On leaving the dryer the dried ore is carried by the conveyor to the dry rock storage building. This ore is now re- garded as mill feed. The “overs” are then further screened. The “throughs” from these secondary screenings are dispatched by conveyor to the dry rock storage building via the dryer. The screened “overs” are then subjected to further impaction by a Hazemag Crusher. After this impaction the “fines” are screened out and transported to the dry rock storage building, while the remain- ing barren rock, or waste, which amounts to approximately thirty per- cent of the ore delivered, is conveyed to the tailings pile. THE DRY ROCK STORAGE BUILDING On leaving the dryer building the ore is conveyed to the dry rock building which is capable of storing 40,000 tons of mill feed. An elevated shuttle belt conveyor within the building distributes the ore into predetermined piles, ac- cording to grade. Thus, for production purposes, mill feed can be “blended” as required. A large five cubic yard Payloader moves the blended ore to the conveyor system that supplies the mill.
