From a number of studies in gas -solids cyclone separators which have been reported in literature,
it is shown that, developing more efficient cyclone separators have been essentially based on
experiments rather than mathematical models. One of the main perfolmance characteristics of the
gas - solids cyclone separators is the collection efficiency. The principle object of this work is to
study experimentally the effect of some of the major controlling parameters that have direct effect
on the cyclone performance, essentially on the gas - solids cyclone separators collection
efficiency. These parameters are the cyclone size, properties of solid phase and air inlet velocity.
The results obtained showed that collection efficiency increases with increasing the cyclone size,
particle size and inlet velocity.
