Description:

Sormac SO-50/250 R screw destoner

Operating principle

The screw de-stoner can be used inconjunction with all root crops. The integration of this system into a processing
line dramatically reduces the potential for extreme wear and tear to associated equipment further along the installation.
The screw de-stoner is constructed with a rectangular reception hopper with a vertical transport screw. The screw is driven by a reduction gearbox.
The circular water filled hopper receives the product to be de-stoned and in combination with the rotational action of the vertical screw auger draws the water and crop gently up the tube supported by the regular closed screw. For a better separation of the sand out off polluted products, also a round reception hopper with cone can be used. The rotational action raises the product allowing the water to gravitate down the side of the auger. Heavy
particles with negative buoyancy remain on the bottom of the hopper. Clean product (without stones) are transported out off the upper side of the transport screw.

Capacity 

The capacity of the machine depends on the size of the product, and can be max.5 tons/hour (11,000 lbs/hr).
