Gravity Separation | Henan Deya Machinery Co., Ltd.
A guideline for separability by gravity based on this concentration criterion is given in Table 2. Figure 1 shows these limitations graphically over a separation curve. Separation is possible above the line and impossible for concentration criteria below the line. Table 2 shows that separation will be easier in a fluid of higher density.
