F = Initial density (Parts Water to Sol­ids by weight). D = Final density to which pulp will settle or density at which you want to discharge pulp from thickener. R = Settling rate in feet per hour. Usually it is desired to discharge pulp from the thickener

The main gear consists of a rim with internally machined teeth so that the space in the center is left free for a post that is bolted to the top of the column and supports the walkway. It should be noted that the structure that spans radially on a column type thickener is not subjected to any operational load and serves merely as the inner support

Critical review of thickener design methods SpringerLink

In this chapter we analyze different methods of thickener design that have been proposed in the literature, in the light of their physical foundations. We distinguish three types of methods: (1) those based on the macroscopic balances, (2) those based on kinematical models and (3) those based on dynamical models.
