Separators in the cement industry

The separation is mainly realized by two forces: the centrifugal force and the drag force. The drag force produced by the airflow on a particle is proportional to the cross-sectional area of the particle, on the other hand the centrifugal force is proportional to the mass (volume) of the particle.

Cement Industry Overview

The cement industry has boosted efficiency by concentrating new capital investment in plants that use the dry process of cement manufacture, and by phasing out operations that rely on the more energy-intensive wet process. Since 1974, the number of wet process kilns has dropped from 234 to 25 -- a decline of 89 percent -- while the number of dry process kilns has only been reduced from 198 to ...

Cyclonic separation - Wikipedia

Cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. When removing particulate matter from liquid, a hydrocyclone is used; while from gas, a gas cyclone is used. Rotational effects and gravity are used to separate mixtures of solids and fluids.
