1.
Principle
- The sieve box
which is normally equipped with two-layer sieves is supported by
hollow rubber springs and is caused to oscillate by one or two
vibrators depending on machine execution.
-
The grain is spread by a feeder across the entire width of the
machine, and then the product stream is stratified on the
pre-separation screen according to its specific gravity by the
oscillating motion of the screen and by the air flowing through the
product from bottom to top. The light particles collect at the top,
and the heavy ones including the stones at the
bottom.
- The lower layer with the heavy
particles flows upward and is fed to the final separation zone of
the bottom de-stoning screen. Final separation of the stones from
the grain is accomplished by a countercurrent of
air.
- The stone-free product streams on the
two screens float on cushions of air, flowing slowly toward the
product outlet, and then are discharged through the squeezed rubber
valves.
- To achieve the optimum degree of
separation, the inclination of the screens, the air volume and
final separation can be adjusted
accordingly.

Features
- Advanced design and
excellent fabricating
- Reliable and
excellent stone separation and efficient
cleaning
- High specific
capacity
- Easy operation and
maintenance
- Two options: with or without
air-recycling system.
- A fan is equipped on
the air-recycling type and a special separator is installed ahead
of the fan. The separator deflects the aspirated air through a
lamellar system so that dust and chaff are separated from the air
and discharged by an airlock valve while the cleaned air is
recycled by the fan in the air return pipe to the
destoner.
3.
Application
- The machine is
designed for separating stones from a continuous product
stream
- On the basis of differences in
specific gravity, reliable removal of high-density impurities such
as stones and pieces of metal and glass is
achieved.
- Versatile application
in flour mills, rice mills, feed mils and seeds selection
processing.
