destoner
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.
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.
