  • Development of a high capacity, low cut spiral for the coal industry

    South African coal mines largely use spirals to clean coal of 2 mm x 0.15 mm in size. In some cases spirals are used to treat feed with a top size of 3 mm. The MX7 model has been used for decades as a spiral of choice for fine coal cleaning, especially for the difficult to clean coal (Klima & Benusa, 2006). The MX7 spiral has a recommended
