What is Free Fall Metal Separator?

The Free Fall Metal Separator is used for the inspection of bulk materials in free-fall conveyor pipes. It detects all magnetic and non-magnetic metal contaminations (steel, stainless steel, aluminium, ...) - even if such contaminations are embedded in the product. Metal contaminations are rejected by means of a swivel hopper.

Vertical Fall is a gravity fed / throat metal detector system designed for inspecting bulk, powders and granules.  It is ideal for checking early in the production process to detect metal before the product moves down the line, minimising the potential cost of wastage and protecting other processing equipment.

Where is Metal Detector Applied ?

The metal separator is suitable for detecting powder and bulk products, such as rice, flour, beans, cereals, peanuts, grains, corn, sugar, confectionery, chemicals, nuts, powder and bulk goods.

What Hazards of Metal Impurities ?

  • Damage the screw, block the nozzle, mold runner (hot runner)

  • Metal scratches the mold, increasing the maintenance burden

  • Scratch the surface of the finished product and affect the product quality

  • Increase the pressure of the hot runner and cause the plastic flow to block

  • The finished product contains metal, causing short circuit and non-insulation

What are the Features ?
  • ◪  Vibration screen feed: Evenly feeding without clogging, high separation quality

  •  Fast Detection: Can quickly separate all kinds of metals such as steel, copper, aluminum, stainless steel, etc

  • ◪  High Sensitivity: Metal particles as small as 0.2 mm or long wire can also be separated

  • ◪  Easy to Use and Install: Directly installed on the production equipment (such as injection molding machine), can be multiple protection, to avoid metal particles damage equipment
