Before Buying The Right Metal Separator, You’d Better Know The Type
Metal separators are widely used and can be applied to most industries. You may have just thought of buying a metal separator for your product, but there are many types on the market. The most sensible way is to understand its classification before you buy a metal separator, which can prevent you from being fooled by the manufacturer.
Metal separators are classified according to the transportation mode of the tested items. Metal separators are usually divided into channel, falling and pipeline sparator.
Channel metal separator
The most common metal detection equipment on the market is a channel-type metal separator. The channel of the detector is square. Generally, it is equipped with a conveyor belt mechanism with an automatic rejection device or provides an alarm signal. When the items on the conveyor belt pass through the detector, once there is metal, it will automatically be rejected or stop conveying. Mainly for on-line inspection of finished and semi-finished products, providing final inspection before shipment. For example: bagged materials, boxed products, etc.
Pipeline metal separator
General metal separators cannot fully monitor the entire production process of fluid products, such as ham meat sauce, chewing gum, oral liquid, etc., and remove metal impurities online in real time to ensure that the product is safely transported to the next process. Under normal circumstances, these products are encapsulated in metal, and generally cannot be detected with a metal separator after becoming a finished product. In addition, the detection of liquid or viscous items before canning or packaging can effectively improve the detection accuracy.
Falling metal separator
Falling metal separators are generally equipped with automatic rejection devices, so they are used to call them falling metal separators or metal separators.
The packaging requirements of the metal separator for the product is that it cannot contain metal, but considering the higher requirements of tightness and light resistance, it must be packaged with a metal composite film. The metal composite film itself is metal, so if a channel-type metal separator is used, the detection sensitivity will have a large deviation, or even be unable to detect.
In view of the above reasons, you can choose to test before packaging. The falling metal separator was developed in response to the above situation, and is mainly used for the detection of tablets, capsules and granular (plastic particles, etc.) and powdered objects. When these items fall through the falling metal separator, once metal impurities ASTM B549 are detected, the system immediately activates the separation mechanism to eliminate suspicious items. It has the characteristics of simple installation, high sensitivity, convenient maintenance, high efficiency, stability and reliability.
It can be used for powder, rice sugar, oatmeal, cereals, bulk snacks, plastic/chemical raw materials. And, the channel size can be customizable.
