A free fall metal detector is a type of metal detection system used in various industries, particularly in food processing, pharmaceuticals, and plastics. It is designed to detect metal contaminants in falling streams of material, such as powders, granules, or other bulk products.
A free fall metal detector typically consists of a sensing head, a control unit, and an reject device. The sensing head is mounted around a chute or pipe through which the material falls, and it detects any metal particles present in the stream. If metal is detected, the control unit signals the reject device to divert the contaminated material away from the main product flow.
Free fall metal detectors are commonly used to:
1. Ensure product safety by detecting metal contaminants that could harm consumers.
2. Prevent damage to processing equipment caused by metal particles.
3. Reduce waste and minimize the risk of product recall.
These detectors are highly sensitive and can detect even small metal particles, making them an essential quality control measure in various industries.
