TWO STAGE CLEANING REMOVES DUST, SAND, STONES, METAL, GLASS AND JUTE FIBRES

Along with dust and sand the delivered raw product usual-ly contains coarse foreign material such as stones, metal, glass or jute fibres.
This foreign material must be com-pletely removed for quality reasons as well as to protect downstream processing equipment against excessive wear.

• The sieve box is fastened by dual ropes on each corner in a free-swinging way, instead of using rubber pads. The circular movement of the circular oscillating plan sieve is generated by a rotor with crankshaft drive, thus running smooth, quiet and nearly vibration free, compared to un- balance vibration drives. The screen surface is generous-ly designed, the air quantity is high.
• The de-stoner also is equipped with crankshaft drive. To support the air adjustment, the de-stoner furthermore is equipped with an incorporated high-pressure fan, situat- ed below the generously designed sorting table. The sep-arating air – required to lift-up the beans on the sorting table – cannot be easily influenced or even disturbed when changing parameters at the aspiration system, shared with the screener. With this execution a free access to the sorting table can also be obtained during operation.
