Composition and classification of metal detection separator Metal detection separators also have many different classifications for different applications. What is not the case is that in general , the metal detection separator consists of two parts, a metal separator and an automatic rejection device, in which the detector is the core part. There are three sets of coils inside the detector, namely the central transmitting coil and two equal receiving coils. The high-frequency variable magnetic field is generated by the oscillator connected to the intermediate transmitting coil. The induced voltage of the receiving coils on both sides in the idle state. The magnetic fields cancel each other before the magnetic field is undisturbed to reach an equilibrium state. Once the metal impurities enter the magnetic field, the magnetic field is disturbed, and the balance is broken. The induced voltages of the two receiving coils cannot be cancelled. The un-accelerated induced voltage is amplified by the control system and generates an alarm signal (detecting metal impurities) ). The system can use the alarm signal to drive an automatic reject device or the like to exclude metal impurities from the production line. 　　 Also under normal circumstances, the method of conveying the detected articles is divided into three types: metal detection separators are generally divided into: channel type, drop type and pipeline type. Falling metal separator Falling metal separators are generally equipped with automatic rejecting devices, so it is customary to call a falling metal separator or a metal separator. 　　 Now the falling type metal detection separator is also a relatively common metal detection separator. The metal detection separator does not contain metal for the packaging requirements of the product, but it must be adopted in consideration of high requirements such as sealing and light protection. The metal composite film is packaged. The falling metal separator was developed for the above-mentioned situation and is mainly used for the detection of powdered articles such as tablets, capsules and granules (plastic particles, etc.). When these items fall through the falling metal separator, 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. Channel type metal detection separator At present, the common metal detection equipment on the market is a channel type metal separator, and the channels of the detector are square, generally matched with Conveyor belt mechanism with automatic reject device or 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.   Pipeline metal detection separator The general metal separator can not completely monitor the entire production process of the fluid product, such as the meat sauce, chewing gum, oral liquid, etc. of the ham sausage, and remove the metal impurities in real time to ensure the safe transportation of the product to the next process. Under normal circumstances, these products are all encapsulated in metal. After they become finished products, they are generally not detectable by metal separators. In addition, liquid or viscous items can be detected before canning or packaging, which can effectively improve the detection accuracy. 　 In conclusion, so far, the metal detector is further separator mainly used in food, pharmaceutical and industrial rubber, textile, paper, and recycling of industrial minerals, we can provide meet their requirements metal separator or separators. 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. In the food industry, systems typically use higher operating frequencies. For foods such as cheese, due to their inherent high frequency sensing performance, the response of high frequency signals is proportionally increased. Moist fat or salty substances, such as bread, cheese, sausages, etc., have the same electrical conductivity as metals. In this case, in order to prevent the system from giving an error signal, the compensation signal must be adjusted to reduce the sensitivity. 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 detection separators are usually unaffected by the orientation of the installation and can be installed horizontally, vertically and diagonally, and can be installed almost anywhere in the production process.
