    MIP Thickener Design. The following is a short cut to designing your own thickener: (a) Size of Thickener. As a first stab we can either use the thickener flux (m2/tpd) or the rise rate, depending if solids loading is the dominant (eg. Platinum Tailings) or feed flow rate (e.g. Clarification or low feed solids). Say, we have a coal.

  • Understanding the Thickening Process CiteSeerX

    Although predictive models of thickening do exist, the correlation to reality is often poor and there is a desperate need to bring the two together to make rational improvements to thickener design and operation. Therefore, whilst some would dismiss the models as being unacceptable for predictive design, they are very useful.

    The critical concentration therefore constitutes an upper boundary for solids loading, and zone settling imposes an area demand on thickener design. When the feed flux of solids is below the critical value, solids pass down through the zone faster than they are replenished at the top and the zone disappears. Hence, zone.

    These properties must be considered when selecting a rise rate, solids loading, and bed depth for a thickener. Rise rate parametrizes the area required to recover the design flow or solids loading, the design dry tonnage. In high rate thickener (HRT) designs the rise rate or solids loading will dictate the required tank.
