A plastic granulator machine is used to break down plastic products in order to prepare them for recycling. Depending on the industry you&#;re in and the machinery you use, there are various types of plastic granulators for sale. Usually, a plastic granulator is used to process consumer plastics, because they are easier to granulate when compared with nylon or ABS.

If you&#;re looking to add a plastic granulator to your facility, it helps to know the basics of how a granulator functions. It&#;s also helpful to know the difference between granulating and other plastic processes like grinding. Once you understand granulation, you&#;ll have a better idea of what type of plastic granulator machine to purchase.
A plastic granulator breaks down plastic fragments into small pieces for recycling. There are several parts that go into making a plastic granulator, but perhaps the most important is the knife and the rotors.
The knife on the plastic granulator is usually mounted directly on the rotating rotor, or it&#;s on a stationary bed. There is a set of knives used to help break down the plastic. The exact space between the knives depends on the type of plastic you are processing and how. For example, if you have hard plastic materials, you&#;ll want to leave more space between the knives. Knives with a smaller space are better for a cleaner cut on soft plastics.
Knowing which type of knives you need is extremely important in deciding on what plastic granulator to purchase. For example, knives that have blunt tips are used for brittle materials most often. With softer materials, you&#;ll want knives with sharp edges to get more precision.
The rotor is another essential part of a plastic granulator. There are different types of rotors. For example, an open rotor is used for heat-sensitive resins because it allows for a healthy airflow while the material is being cut. A closed rotor doesn&#;t provide space between the knives and the shaft. You&#;d likely use a closed rotor if you need to cut thick materials, because this lack of space allows for more strength in the knives.
Understanding these different elements of a plastic granulator will help you determine which is the best for purchase in plastic processing.
There are dozens of different processes within the plastic industry. You&#;ve likely heard of plastic grinding, which is a way to take a larger material and shrink it so it can be further processed. If you have a large piece of plastic or another raw material that&#;s too big to be shaped, you need a machine that can make this material usable. That&#;s where a grinder comes in. This is common in the rubber and plastic industries, where the size of different products varies widely.
Similarly, a plastic granulator also breaks down materials into smaller pieces, which means it&#;s easy to confuse the two processes. However, a plastic granulator machine is able to reduce materials to much smaller sizes than a grinder. As mentioned, granulators also have a rotor design that can allow for airflow to facilitate cooling. This gives you flexibility in the plastic granulation process. Grinders, however, are always closed, which means there&#;s little to no airflow while they are processing.
Both of these processes may be applicable to your business, but make sure you know which before you purchase a plastic granulator machine. If you can find a reputable plastic processing equipment supplier, they can answer any questions you have about plastic processing and find you the best machine for your facility.
To select a Plastic granulator is not an easy task. A plastic crusher is a high speed and industrial size reduction machine. A wrong model selection may cause a serious consequence. In this article, Wiscon Envirotech will land you on how to choose a plastic granulator in perspective of safety, power consumption, viability, and budget, based on 5 important factors.
First of all , you need to get clear the application of your granulator machine for plastic. You want to just reclaim your plastic waste like purges and non-conforming parts? Then measure the dimension of your waste. Make usre the waste is not contaminated and mixed with metals, because the former needs washing and the latter can damage the blades of granulators. Some oversize plastic item requires primary shredding: plastic shredder.
Secondly, inform us the composition of your plastic wastes. Not all plastics are easy to cope with, for example, engineering plastics like PEEK and reinforced plastic like fiberglass. Hard plastics requires better blades and a different rotor and even augmented motor power.
If you really do not know how to select a model, then tell us the size and composition of your waste, the final size as well as how to feed materials and collects the regrinds. With our experience in plastic recycling, we can offer you a complete solution.

A larger model is designed with a bigger crushing chamber and bigger infeed hopper. With these 2 combined, a plastic crusher can process objects in bigger size and tougher construction. Of couse, bigger always more expansive. Beware to set up your budget first, and next match your biggest plastic waste in hand to the infeed hopper size. Make sure the item can enter the infeed hopper and fall into the crushing chamber smoothly.
The electric motor is one of the most expensive parts used in a plastic granulator. To reduce costs, many suppliers, especially in Asia, choose to use an inferior motor to achieve competitive prices. It is not necessarily true that a faster motor will produce better results, but it is the combination of various factors (e.g. dynamtic balancing, drive belts and bearing) that produces the best crushing efficiency. Wiscon Envirotech adopts second grade power-efficient motor, which in turn will save your power consumption.
Wiscon Envirotech manufactures our own knives for granulator. It is the blades that are making contact with and shearing the plastic materials, so the blades should withstand wearing and shock. A crusher blade featuring long sercie life, hard and easy to install is our thumb of rules of developing crusher blades. This is one of the key to select a plastic granulator.
Number of knives: The number of knives used in each granulator is different and based on the design. While common granulators are equipped with 3-6 rotor knives and 2-3 bed or fixed knives, some models may have more than 30 rotor knives. It is the combination of cutting chamber size, pelletizer type, number of knives and motor speed that affects the overall speed of a pelletizer.
The regrind size relies on screen opening size. We recommend the regrind size to be from 8mm to 20mm, but 12mm (0.5 inch) is the standard. Under the same specs of a plastic grinder, smaller the screen size results in smaller output, because it takes a longer time size reduce the plastic waste to the desired size.
There are special screens for flexible materials like plastic films.
Easiness on operation and maintenance?
Does it allow wet granulating (adding water during granulation)?
How tall is the infeed hopper? Do you need a conveyor or manually feed?
Add insulation to reduce noise?
How to collect regrinds?
These quesitons matter to select a plastic granulator.
