What is the working principle of plastic granulator?

The article will talk about what is the working principle of plastic granulator, if you are interested in the machine for recycling plastic, welcome to contact us, we will send you professional suggestions.

Feeding: Recycled plastic raw materials are usually discarded plastic products, such as plastic bottles, plastic bags and so on. If it is plastic film or plastic bags, we need to use a forced feeder to get the material into the inlet quickly. The automatic feeder can shred and push the plastic into the granulator.

Melting and mixing: The plastic raw material enters the granulator machine through a feeding system. Inside the granulator, the plastic is processed at high temperatures and pressures for some time to melt it into extrudable molten plastic. During this process, recycling plants, depending on their needs, sometimes add other chemicals to improve the performance of the plastic or to achieve specific colors and characteristics, common colors of plastic pellets are blue, black and white.

Extrusion: The molten plastic substance is pushed into the extruder section. Inside the extruder, by means of a screw, the molten plastic is passed through a die to form plastic pellets of the desired shape.
