Cement mill notebook

Jan 07, 2015· The principle of separation lies in the use of centrifugal force generated by way of a flow with vortex (cyclone and derivatives, etc.) for static classifiers or a rotating turbine for dynamic classifiers. 9.1 Types of Separators: 9.1.1 Static Separator: Its name is due to the fact of not having rotary parts to do the separation.

Elutriation

Elutriation is a process for separating particles based on their size, shape and density, using a stream of gas or liquid flowing in a direction usually opposite to the direction of sedimentation. This method is mainly used for particles smaller than 1 μm. The smaller or lighter particles rise to the top (overflow) because their terminal sedimentation velocities are lower than the velocity of ...
