Free Flow Metal Detector – Its Significant Benefits To Remove The Pollutants

Posted by Admin on June, 21, 2024

As the name suggests free flow metal detectors are systems that are mounted so that the examined product flow is falling, usually vertically, through the metal detector. Products normally are powders or granules in nature and are in an unpacked state. Common system formations will comprise a fast-acting rejection valve to detect and reject any polluted product. Most rejects are an essential part of the Metal detection system and can be installed at less than 1 meter in height.


Benefits of free flow metal detector

There are a number of benefits to using a free-fall metal detector, these include:


Early removal of pollutants in a process prevents those contaminants from becoming dispersed and spreading through your production line. This decreases the amount of “good” product that is lost.

Slight downstream equipment is sheltered from damage from pieces of metal.

  • Fail-safe operation means toxins will not pass through the production procedure even when the system is deactivated or there is an electrical power supply pause.

  • High volumes of products can be checked continuously.

  • Using multi-spectrum technology that auto-learns means that numerous products can be examined by one device.


Solid design means the unit can be suitable for small spaces and can be retrofitted into existing pipework.

Easy disassembly and washing of components that are in contact with the product means a minimum of

Maintenance downtime.

Common Applications for Free-Fall Metal Detection

Typically flow metal detectors are used in a wide range of uses including the inspection of incoming bulk materials to stop contaminants from entering a factory; in the feed to downstream treating equipment such as extruders and mixers; before tablet presses in pharmaceutical uses and before packing equipment in food processes.


Things to consider before buying a free-flow metal detector


When purchasing this metal detector, several important factors should be taken into account to ensure you select the right equipment for your needs. Here are key considerations:


1. Application and Environment

Type of Material - Identify the type of material you need to inspect (e.g., food products, pharmaceuticals, textiles).

Environment - Consider the environmental conditions where the detector will be used (e.g., wet, dry, extreme temperatures).

2. Detection Sensitivity

Sensitivity Requirements - Determine the level of sensitivity required based on the size and type of contaminants you need to detect.


Product Effect - Understand how the product's characteristics (moisture, salt content, temperature) might affect the detector's performance.

3. Throughput and Speed


Processing Speed - Assess the detector’s ability to handle the volume of materials passing through it within a given time frame.


Conveyor Integration - Ensure the metal detector can integrate seamlessly with your existing conveyor system or production line.


4. Size and Configuration


Detection Aperture Size - Choose an aperture size that fits your product dimensions without compromising detection accuracy.


Physical Footprint - Ensure the metal detector’s physical dimensions fit within your available space.

5. Compliance and Standards


Regulatory Compliance - Verify that the metal detector complies with relevant industry standards and regulations (e.g., FDA, HACCP, BRC).



Certification - Look for certifications such as ISO, CE, or UL that indicate the detector meets quality and safety standards.
