The crusher is the core equipment of the plastic granulator group....

The crusher is the core equipment of the plastic granulator group. It is of great practical significance to ensure the stable operation of the crusher for the whole working process.In the actual operation, to avoid several kinds of granulation fault, find the specific causes, targeted to solve the problem, to avoid the recurrence of similar problems, to make the granulator normal and effective completion of the work, to ensure the quality of particle products, so that the product can leave the factory as scheduled.

Factors pushing the knife, the knife dish in the mill running on the way back, gaps between the cutter and the template, lead to material mat in the middle of the knife and abrasive, sent the knife dish, make whole grain cutting room and subsequent pipeline was die out by mistake in the material block, if the accident is serious, it is melting granulator can resume work with fire.The failure of the granulating machine as if it were an enema is a major factor affecting its orderly operation, which is common in daily operation.

Abnormal particle size factors, our country for the actual granulator cutting standards have a clear stipulation, even including the case of even particles, particles diameter must not exceed 5mm.In the actual process of granulation, it may be greater than or less than this base, and abnormal particles will be formed.Controlling the size of particles is an important production index.

Snakelike particle factor, in the process of granulation, sometimes produce snakelike particle surface, although in its interior is not far from the piece, but its shape is abnormal, also affect the quality of the product.

As the amount of waste plastic is more and more big, do plastic granulation of users also more and more began to choose split type plastic granulation equipment, split type plastic granulation equipment is a machine to take the original host into the main auxiliary two machines, so that the plastic granulation equipment failure rate decreased, use rise also convenient, and can make large production equipment, so as long as it is big production plastic granulation equipment are the fission.

Since chose to split type plastic granulation equipment, you should choose to form a complete set of main auxiliaries, don't in order to pursue cheap, save money, a listen to immediately bought low price, and I don't know don't match, a lot of users buy host of auxiliary equipment eat, this kind of circumstance belongs to host large auxiliary small, such auxiliary feed port will pile of a lot of material can eat, so that the host can't normal use, this kind of circumstance can choose to change a bigger size in net die head, if not yet is the auxiliary machine screw is small, it directly in big auxiliaries.Still have a kind of situation is to host a slow, auxiliary out fast, so took no note and or a very thin sliver of, this kind of circumstance can take auxiliary motor belt rotate a little bit small for auxiliary engine speed slowly try, if not can be the host of the speed of the motor belt rotation a bit bigger let host try to hurry.

Plastic granulation equipment produced by the plastic particles, generally is the particle size distribution, shape but there may appear the problem of uneven grain length of finished product, the reasons of uneven, we should seriously study, finished product is due to uneven plastic granulation equipment production when there is a problem, will cause the emergence of the irregular shape.The appearance of plastic particles is not good, so when this kind of problems, the need to promptly solve the uneven length of the site phenomenon.

The uneven production line of plastic granulating equipment is mainly due to the following reasons:

1. If the voltage is not stable during the production of plastic granulator, the motor speed will be unstable, which will affect the subsequent production process.

2. If there are too many impurities in waste plastic, it will lead to uneven granulation and irregular subsequent production.

3. In the production line of plastic pelleting equipment, if the driving shaft is damaged, it will also affect the finished products and affect the yield of finished products.

With the popularization of plastic and plastic applications, the continuous introduction of special and functional plastics and plastics, meshing coplanar twin-screw plastic granulating equipment and plastic granules to high-speed, high yield, multi-functional, large-scale, precision and intelligent development.

As the important core equipment of plastic and plastic extrusion granulation, meshing coaxial twin-screw plastic granulation equipment and plastic granule machine are also developing towards the direction of high output, large scale and low energy consumption driven by the demand of plastic and plastic market.

The use of plastic granulating equipment makes the environment free from pollution, recycling processing secondary use of plastic.Plasticizing, plasticizing can be divided into “Pure & throughout;And & otherComposite & throughout;Two kinds.

Simple, refers to the resin factory, plastics factory, plastic scrap generated in machining process, gate, waste defective and residue and so on, including some single, batch, clean and waste plastics used only once, river of disposable packaging waste plastic, waste recycling plasticizing, as a secondary source material recycling.

In the waste plastic recycling processing, for pure, at present most of the plastic factory first the factory waste plastic to use, some plasticizing granulation after use, some crushing processing after direct use, some neither broken nor granulation, by the factory digestion.

Compound, the so-called waste plastic recycling, mainly refers to from the community to collect the amount of large, complex varieties, impurities, serious pollution of those waste plastic utilization.The waste plastics, industrial and mining enterprises and agriculture scrap plastic parts, packaging, fertilizer bags, cement bags, pesticide bottle, fishing nets, agricultural film and packaging barrels, etc., with the urban and rural masses food bag, plastic bottles, toys, daily necessities of life and cultural and sports supplies, such as plastic and waste plastics containing a small amount of fillers and plasticizer.For the compound of these miscellaneous, messy, dirty waste plastics, its processing technology is more complex.

The so-called recycling and utilization of waste plastic mainly refers to the use of waste plastic collected from the society in large quantities, complex varieties, impurities and serious pollution.The waste plastics, industrial and mining enterprises and agriculture scrap plastic parts, packaging, fertilizer bags, cement bags, pesticide bottle, fishing nets, agricultural film and packaging barrels, etc., with the urban and rural masses food bag, plastic bottles, toys, daily necessities of life and cultural and sports supplies, such as plastic and waste plastics containing a small amount of fillers and plasticizer.For the compound of these miscellaneous, messy, dirty waste plastics, its processing technology is more complex.
