dc.description.abstract |
In this research, a rotating cylinder viscometer was designed and
fabricated to study the structure formation of particles in a mineral suspension and
its influence on the relative viscosity q/qo. It is known that the value q/qo is affected
by the concentration of suspended mineral particles in an aqueous media. The
relative viscosity q/qo thus obtained is related to the volumetric concentration of
suspended particles by the equation q = qo + k(f>, where the value k depends on
particle behaviour in aqueous medium and is related to the shape, zeta potential
and the volume % of particles. By this method it is possible to classify the suitability
of surface active minerals in mineral deposits on the basis of the k factor. The
rotating cylinder viscometer consists of a cylinder, of known dimensions, immersed
fully in a mineral suspension so that it can be rotated by applying a mechanical
couple (Force X distance) acting on the cylinder by two identical falling weights
which are tied to each other by an inextensible string. Initially the cylinder is made
to rotate in water of known viscosity by fully immersing it, thereafter in the known
suspension. From the rates of rotation, the viscosities can be compared and hence
the k values. |
