2. What's the use of metal detection?

There are usually two reasons for using a metal detector.

(1) protect your valuable equipment or key equipment

(2) make sure your product is perfect

If there is a piece of metal that doesn't know how to do it, it will inevitably damage your equipment, such as your mill, slicer, pulverizer, or cutter .Not only do you waste production time and gold repairing your equipment, but the metal detritus can get smaller and harder to find. It's more important for you to keep your product quality perfect. If you find some metal impurities in your final product, it will probably ruin your company's image and reputation.

Where should I  install the metal detector?


If you use a metal detector in order to protect your device, you should install the metal detector at the entrances to the distance protection device as close as possible, but to set aside enough space again, when makes the metal detector to detect metal can stop in front of the metal into the equipment.

If metal detectors are used to test your final product, the probe should be installed at the end of the production line as much as possible. In theory, this avoids the possibility of mixing metal in the packaging.

If the package itself contains metal or the final packaging is too large to be well detected, the metal detector should be installed before the packaging machine.


4. How to select a suitable metal detector?


Metal detectors can be trusted with sensitivity, reliability and accuracy. The key is to apply to you. Make sure the probe size is just enough to ensure that the product you're looking for can be found in all directions. The probe head is installed in the right place. Then, choose a professional manufacturer that Provide technical support for you


5. What is the product effect?

In fact, all products, when they pass through the electromagnetic fields in the region, produce certain types

The signal.Factors affecting the product effect signal include moisture content, fat content, temperature, acidity, salinity, direction and volume. Products with small product effect can get high detection sensitivity. Metal detectors can also be used to improve the detection sensitivity of metal, which has an unparalleled advantage in digital metal detectors.


6. What is sensitivity?


The sensitivity of the metal detector is defined as the diameter of the smallest metal ball that can be detected in the center of the probe. Sensitivity is also divided into "maximum sensitivity" and "product detection sensitivity". Maximum sensitivity is the maximum sensitivity of a metal detector under the theory bar. The detection sensitivity of the product refers to the maximum sensitivity of the metal in the product in the actual application. It is more practical to wear the detection sensitivity.


7. Which factors affect sensitivity?

The sensitivity of the metal detector is determined by many factors: the product effect, the shape, size and direction of the metal impurities, the size of the probe, and the operating environment.

8. What are different kinds of metals?

Iron metal is a good guide for magnetic metals.Carbon steel and iron, for example, are the easiest to detect.Non-ferrous metals are also non-magnetic metals.Copper, lead, yellow steel, bronze, etc., are also easier to detect.Non-magnetic stainless steel, such as 302, 304 and 316 are the most difficult metals to detect. Normally, a metal detector can detect a non-magnetic type of stainless steel that is at least 1.5 to 2 times the diameter of the iron that can be detected.


9.What should I do after I detect the metal?

Many metal detectors are equipped with automatic removal devices, which can automatically remove products containing metal impurities from production lines when the metal is detected.This can help collect and test where the metal impurities come from. The shedding of small fragments of metal is a precursor to big problems.If there is no automatic removal device, the product with metal impurity should be removed manually.Also find the source of the metal and analyze the cause.


10.How does the metal detector fit the HACCP standard?

Metallic foreign body detection is the key control point of HACCP.Metal detectors are ideal instruments to ensure that your product does not contain metallic impurities.Low price, convenient operation, safe, pollution-free and reliable.The main purpose of HACCP is to make a reasonable production flow for your assembly line. Find out where your production line may be easily mixed with impurities and provide a set of ways to ensure that your product is free of impurities. The main part of any HACCP plan is these inspection procedures.
