Separators are widely used for production
of construction and abrasive materials as
well as in chemical industry, food industry,
pharmaceutical industry, heat-power engineering,
metal production industry and mineral
concentration facilities. All processes
which involve separators can be categorized
into two large groups: dry separation and wash separation.
Dry separators are used to divide granular
materials into homogeneous fractions on the
basis of their physical properties.
This research is focused on development of
new designs for separators and creation of
mathematical models for these designs as well
as creation of mathematical models for existing
separator designs. The purpose of mathematical
modeling is to determine optimal operation modes
for separators and analyze their design efficiency.
The designed separators are intended for
classification of small-size particles (5 to 10 mkm)
as well as medium-size particles (0.01 to 1.5 mm).
One of designed separators was tested; the test
was to extract granular gold from gold ore concentrate.
The new design eliminated problems related
to process continuity, adjustment of some design
parameters and exclusion of fast-wearing elements.
The test was performed for particles whose masses
were
kg and radiuses
were
mm. The obtained
granular gold output efficiency was 90-97%.
