The DPR gravity stoner has been designed
for the splitting of light and heavy wheat
fractions, the separation of stones and
other light specific weight materials and
the partial elimination of dust and other
impurities.
When the product reaches the upper sieve,
vibrations and the circulating air produce
a separation, the light grain is driven
towards the outlet and the heavy grain falls
on the lower sieve along with the stones.
At this stage, the same process is performed,
separating stones from the product which
falls into the heavy grain hopper.
The frequency and extension of vibrations,
the perforation of the sieve and the suspension
effect produced by the air causing the grain
to be lifted up, allow a precise operation
which ensures a correct separation. |
