Metal detector for free falling products

The METAL SHARK® GF (Gravity Feed) is used for pipes with free-falling materials to detect metal contamination in continuously falling granules or powders such as sugar, flour, grains or spices.

Sensors detect even the tiniest metal contaminants, and fast-reacting drop valves eject them directly from the product stream during production.

Reliable metal detectors in free-falling goods
Easy assembly thanks to the mounting frame and quick release rings
Maintenance free due to automatic balancing and calibration control
ATEX version for use in potentially explosive atmospheres
BRC-Kit option: Compliance with the British Retail Consortium (BRC) global food safety standard

Feed and drop system	Available pipe diameter from 50 to 300mm; The drop system is available for pipes from 50 to 250 mm; The dropping system EX-P compact is intended for products in the form of flour, EX-S compact is intended for products such as nuts, grains; EX-K abrasive products, robust; EX-CB (cereals, nuts, does not damage the product).
Stand	Optional: Stainless steel stand.
Flow rate	A pipe with a diameter of 100 mm passes 20,000 l/h, a pipe with a diameter of 300 mm – 165,000 l/h, measurements were made using dry sugar;
Best metal sensitivity	100 mm pipe Fe 0.5/Nfe 0.7/SS 0.8 mm; 300 mm pipe Fe 1.9/Nfe 2.4/SS 3.0 mm; These are only approximate values, parameters may change depending on detector modifications.
Product management and rejection system	FDA compliant construction where all parts in contact with the product are made of stainless steel and PVDF. The 300mm diameter tube does not have FDA approval.
