Unique Gravity Feed Metal Detector
systems are to designed inspect any free flowing bulk
powder or granular materials such as Pharmaceuticals,
plastic pellet, cereals, flour and chemicals. Any free
flowing materials may be passed through the vertical
drop system. The unit fits into an existing pipeline or
beneath a feed hopper and the product fall by gravity.
The metal free product passes straight through the
mechanism and diverts the ferrous and non ferrous and
stainless steel contamination from the main floor.
Rectangular and larger throughput systems are available
to special order, suitable for floor or suspended
The high feed flap reject ensures positive rejection of
metal contamination every time unlike "Trouser Leg" when
rejection of the good materials.
The material to be examined is send through the
equipment in free fall. Uncontaminated material passes
unaffected by the reject device. If metal is detected by
the metal detector solenoid operates a flap and diverts
the contaminated material. After an adjustable period of
time the "Rejection Duration" the flap returns to its
The valve is mounted beneath the detector at the minimum
distance to ensure it can fully close before
contamination arrives when under maximum load. The
complete mechanism has smooth flow lines and can be
quickly dismantled for cleaning if required.
