Generally in the plastic industry, as well as the food industry will use metal separators, the use of metal separators is mainly to control the purity of raw materials, protect production equipment, and then ensure the production schedule, avoid customer complaints, maintain the corporate image, and as a GMP, GAMP, FDA, IFS, ISO9001 and other related certification links. The use of metal separators can fully maintain the smooth progress of the production process and effectively protect the production machinery of the production line, especially in the process of recycled plastic granulation and injection molding, it is not easy to wear the screw and the barrel and block the nozzle.
Working principle of plastic metal separator:
Raw materials from the hopper or feeder free fall through the plastic masterbatch metal separator, if there is no metal impurities, raw materials will directly through the plastic masterbatch metal separator induction area straight down the storage box, if the detector detects metal in the raw material, then the diverter valve will act, the metal and a small part of the raw material diverter out, and then the diverter plate quickly returns to the normal position, The speed of the shunt plate is adjustable, the induction precision is adjustable according to the production needs, and even metal particles as small as 0.4MM can be detected and separated.
At the same time, the use of plastic metal separator also provides quality services for the inspection of raw products, and plays a good role in the detection and separation of metal impurities when recycling various plastic mouthpieces. The plastic metal separator itself is a self-falling energy saving and consumption reducing environmental protection machinery.
Use of plastic metal separator:
1, can quickly separate various metals such as steel, copper, aluminum, stainless steel, etc.
2, less than 0.4 mm of metal particles or long wire can also be separated.
3, installed on the production equipment, can be multiple protection to avoid metal particles damage to the equipment.
4, can be manually excluded, can be manually excluded in a few seconds, and easy to clean.
5, specially for slow flow fall products (such as fiber, very light and very rough products) to provide suitable exclusion structure.
6, with more than 0.3ba overload practical application, to meet the requirements of high temperature heat resistance.
Metal separators are widely used in plastic raw material suppliers, but in recent years, metal separators have also been purchased by the majority of plastic products manufacturers for their own use, as a detection and filtration equipment of metal separators can filter out metal substances mixed in plastic raw materials, whether magnetic metal or non-magnetic metal can be well filtered out by metal separators, especially suitable for some plastic suppliers, After most of the second-hand materials are broken, more or less will leave some metal substances, if it is not filtered out, it will affect the operation of the machine, and it will directly destroy the injection molding machine.
In the production process of modified plastics, the commonly used metal separation equipment is strong magnetic (magnetic flux more than 10,000 Gauss), but the strong magnetic can only absorb ferrous metals, for copper, stainless steel, aluminum and other metals can not be separated, and the metal separator can just make up for the shortcomings of the strong magnetic equipment.
The above is the introduction of the working principle and use of the plastic metal separator, which is specially made for the plastic industry, with magnetic (drum magnetic separator and magnetic frame) and non-magnetic metal separator two kinds of distinction; Drum magnetic separator and magnetic frame can only separate the magnetic metal in the plastic; The non-magnetic metal separator is an induction principle that can induce and separate magnetic or non-magnetic metals. In the production process, when there are non-magnetic metal impurities such as copper, aluminum and lead in plastic raw materials, it can play a good role in detection and separation treatment, especially in the process of injection molding and recycling of old materials.
