Recycled plastic pellets machine is a commonly used equipment for the production of plastic granules. The way of cutting granules refers to the way of cutting the granules, and there are the following common ones
Air-cooled pelletizing method
This method utilizes air to cool the pellets so that a hard shell is formed on their surface, thus enabling the cutting of the pellets.
This method is suitable for finer particles, such as PE, PP, and other plastics. The advantage is that the cutting speed is fast, the disadvantage is that the particles are fragile and easy to produce burrs.
Water-cooled pelletizing method
This method utilizes water to cool the pellets so that a lubricating layer is formed on the surface, thus enabling the cutting of the pellets.
This method is suitable for larger-sized pellets, such as ABS, PC, and other plastics. The advantage is that the cutting effect is good, the disadvantage is that a large amount of water is required.
Hot shear pelletizing
This method cuts pellets by heating them to soften them before cutting them.
This method is suitable for all types of plastics. The advantage is high cutting accuracy, the disadvantage is that it requires a long cutting time.
In a word, recycled plastic pellets machine can choose different cutting methods according to different kinds of plastics and requirements to achieve the best production effect.
