The metal detectors are generally divided into: channel type, drop type and pipeline type.

Channel Metal Detector At present, the common metal detection equipment on the market is a channel type metal detector. The channel of the detector is square, generally equipped with a conveyor belt mechanism, with an automatic rejection device, or providing an alarm signal. When the items on the conveyor pass through the detector, they are automatically rejected or stopped as soon as there is metal. Mainly for on-line inspection of finished and semi-finished products, providing pre-shipment inspection.

For example: bagged materials, boxed products, etc.

Style drop off a metal detector <br> <br> style metal detectors are generally removed with automatic means used to call it off style metal detector, or a metal detector.

The metal detector does not contain metal for the packaging requirements of the product, but it must be packaged with a metal composite film in consideration of high requirements such as sealing property and light protection. The metal composite film itself is a metal, so if a channel type metal detector is used, the detection sensitivity will be greatly deviated or even impossible to detect. For the above reasons, you can choose to test before packaging. Drop-type metal detectors have been developed for the above-mentioned situations, and are mainly used for the detection of powdered articles such as tablets, capsules and granules (plastic particles, etc.). When these items fall through the drop metal detector, the system immediately activates the separation mechanism to remove suspicious items once metal impurities are detected. It has the characteristics of simple installation, high sensitivity, convenient maintenance, high efficiency, stability and reliability.

Pipeline metal detector <br> <br> general metal detectors are not fully monitor the entire production process fluid products, such as sausage meat, chewing gum, oral liquid, eliminate metallic impurities on-line, to ensure product safety Transfer to the next process. Under normal circumstances, these products are all encapsulated in metal. After they become finished products, they are generally not detectable with metal detectors. In addition, liquid or viscous items can be detected before canning or packaging, which can effectively improve the detection accuracy. Whether it's the food, pharmaceutical and rubber industries, or the textile, paper, ore and recycling industries, we offer metal detectors or separators that meet their requirements. In addition to the above-mentioned three types of channel type, falling body type and pipeline type, there are also pipeline type and flat type which are suitable for air delivery vacuum transportation.

Flat type:

It is commonly used to detect products that are thinner in thickness but larger in width and length, such as woven fabrics and extruded sheets. Its primary purpose is to protect downstream equipment such as cutting tools, calendering systems, etc., while improving product quality.

Metal detectors and separators are usually unaffected by the orientation of the installation and can be mounted horizontally, vertically and diagonally, and can be installed almost anywhere in the production process.
