Vibrating Screen |
Vibrating screens work
on circular motion. The vibrating screens are mainly used
in coal dressing, metallurgy, mine, power station, water
conservancy project, building industry, light industry and
chemical industry etc They are efficient screening machines
for the classification of bulk material such as coal, minerals,
coke etc There are 40 specifications for YA series, of which
the heavy duty type is for the classification of large size
materials, while the Light duty type is for the middle and
small size materials.
Vibrating Screen moves round .It has multi-layers and
is of high efficiency. The eccentric shaft vibration exciter
and partial block help to adjust amplitude. The material
drops down along the long line.

Illustration of How CIRCULAR VIBRATING SCREEN Operates
Load the stuff for grinding evenly and continuously into the grinding
chamber of the main frame. Due to the centrifugal force in rotation, the
roller swings outward and presses closely upon the ring. The shovel carries
the stuff to the space between the roller and ring. When the roller rolls,
the stuff is thus grinded.After being grinded, the stuff is to be routed
to the sorter along the wind belt of the blower and the rough powder will
be put back to the grinder for regrinding. The fine powder flows into
the product cyclone collector together with airflow and is expelled from
the powder output pipe as product.In screen grading, the material
is separated mechanically
on screen plates. Rolling bearings in vibrating screens are stressed
by high, mostly shock-type loads. Moreover, the bearings, while rotating
about their own axis,
