    Before looking at the desliming cyclone design, a look at the spiral process design is required. The optimal feed size range to a coal spiral range from 106 m – 2000 m and the recommended feed solids concentration ranges between 25 - 35 %(m/m) (ACPS,2007). These values are presented in a graphical format in Figure 5

    Since cyclones are not 100% efficient, some ultra-fine coal is still contained in the spiral (or other unit) feed and much of these ultra-fines report to the spiral product. The ultra-fine coal usually has high ash content and downgrades the spiral product as a result. Table 1 below shows the size and ash content distribution for a typical
