Plastic Pelletizing Machines – Make Pellets Out Of Waste Plastic But do you know what determines the quality of the plastic pellets from these machines? Let’s find out!
How a cutter design determines plastic pellets
A plastic pelletizing machine is designed to cut plastic materials in order to produce plastic pellets, so the cutter design is very essential for determining the size and shape of the plastic pellets. This cutter must be sharp and straight, so as to produce plastic pellets of identical dimensions. Some shredders are equipped with a stave, and if the cutter becomes dull or is not set correctly, it can produce non-uniform pellets that are of poor quality.
Screw Speed: Why It Matters for Making Pellets
The screw speed is also relevant for the quality of the plastic pellets produced by the pelletising machine plastic granulator. The speed of the screw is responsible for the rate of introducing the plastic and the melt mixing and pressing. A screw speed that is either too fast or too slow can lead to issues such as poor shape and size of pellet.
Ensuring Quality Pellets by Maintaining the Proper Temperature
Another critical factor in ensuring the plastic pellets are high quality is temperature control. So the temperature of the plastic must be monitored in the pelletisation process. If the temperature is too high or too low, this affects the quality of the pellets and can lead to problems such as brittleness, or irregular coloring.
Screen Size Impact on Pellet Quality
The screen size of a plastic pelletizing machine defines the hole size of holes the plastic passes through in pelletizing. The size of the screen determines the consistency of the pellets as it controls the size and shape. Edge pelletisation leads to a difference in size and shape of the pellets hence affecting the overall productivity if the screen size is not correct.
How to Select a Plastic Pelletizing Machine
If you are in the pulp and paper industry, you are probably trying to buy the best quality plastic pelletizing machine. Cutter design, screw speed, temperature control, and screen size are among the factors. In order to ensure high-quality plastic pellets, it is important to select a pellet granulator machine that is well-designed and well-maintained.
