Recycle materials for plastic recycle machine

Shuliy plastic recycle machine can process both post-industrial waste (in-house waste) for plastic producers, and post-consumer waste for plastic recycling factories.

Post-industrial waste: defective products and cut-offs are the common recycle materials, such as LDPE zipper bag production waste, LDPP film scrap, HDPE soft irrigation pipes, bubble wrap, PE/PP packaging bag cut-offs, injection molded products, blow-molded products, thermoformed products, etc.

As for the post-consumer waste, the recycle materials are various. They include PP/LDPE/HDPE regrinds, PP raffia bags, used agriculture films, cement bags, plastic lumps/bulks, PP ropes, jumbo bags, woven bags, non-woven sacks, food containers, jerry cans, PP bumpers, electronic and automotive waste, pipes etc.

If your recycle materials are other materials, feel free to consult us.

Technical details of plastic pelletizing machine

The model of this plastic scrap granulator is mainly divided according to the diameter of the screw press.

1. The screw material of the recycle machine is 45 # steel, 40CR, 38CRSI. Customers can also customize chrome plating, nitriding, and other processes to extend the service life of the machine according to their plastic recycling characteristics.
2. The reducer of the plastic pelletizing machine adopts a hard gear surface reducer. The reducer is an important component of plastic granulator, so quality is particularly important. At present, the quality ranking of common reducers on the market is old-style snail reducer <common reducer <semi-hard gear surface reducer <hard gear surface reducer.
3. There are two kinds of die heads for plastic pelletizer machine for sale: electric die heads and hydraulic die heads. The hydraulic die head can change the filter screen without stopping. It is more suitable for material with more impurities, but the cost is higher correspondingly.
4. The heating mode of the plastic pelletizing machine is divided into the cast aluminum heating ring, quartz tube heating ring, ceramic heating ring, and electromagnetic heating ring. The heating effect of electromagnetic heating is the best, the temperature can be added quickly and the effect of constant temperature is good, but it is not suitable for processing foam material. The heating method can be comprehensively considered according to the raw materials of the customer and the color of the final product.

Structure of the plastics granulator

The plastic granulator machine is mainly composed of a feeding port, screw press, press chamber, heating device, discharge port, mold head, reducer, machine body, base, motor, and other parts.

This plastic pelletizing machine is the main machine of the plastic recycling line and can handle a variety of plastic materials. But the plastic granulator machines that handle different materials are not exactly the same. Their appearance is similar, but the diameter of the internal screw, the distance between the screw and the barrel wall, and the length of the screw are all different. They all need to be adjusted according to the material. Therefore, one plastics graulator machine cannot handle multiple materials.

How to operate plastic scrap granulator?

A plastic pelletizer machine for sale is used to melt and extrude plastics of various materials. The following words we will introduce you how to operate it.

1. First, turn on the plastic granulator.

2. Secondly, observe the operation of the plastic recycle machine, and put it into use after there is no abnormal sound or vibration.

3. Thirdly, it is necessary to preheat the plastic film pelletizing machine so that it can melt the plastic. If the temperature is too high, the melted plastic will turn black; if the temperature is too low, the plastic will not melt.

4. Put the crushed material into the feeding port of the plastic granulator, and add a forced feeder for plastic film material to prevent the plastic pelletizing machine from not feeding.

5. The material melts in the squeezing chamber and is pushed out continuously along with the squeezing screw. The material from the main engine will enter the auxiliary engine again for secondary melting and extrusion.

6. The material from the outlet can be put into the cooling tank for cooling.

Re-usable and high-quality plastic pellets

Pellets produced by recycling machines can be put directly back into the production line, usually for blown film， injection molded items, or pipe extrusion processes.

• On average, post-industrial waste accounts for 4% or more of a production line, so many factories are now equipped with plastics recycling machines to recycle plastic trimmings， in this way, producers can reduce raw material purchasing costs. Since the quality of the trimmings is the same as new, they can be pelletized and used to produce high-quality plastic products.
• Recycling plants collect waste plastic materials from various places. After being washed, these plastic scraps can be recycled into plastic pellets using Shuliy granulators. The plastic recyclers usually add masterbatch or additives in the pelletizing process, so they can change the color and improve granules’ quality.

Heating methods of plastic pelletizing machine

We provide different heating methods, including electromagnetic heating, ceramic heating device and Iron heating. The electromagnetic method is the most efficient one, when you choose a set of mother-baby plastic pelletizer machines, we recommend you choose the electromagnetic method for the host machine. For the second machine, it is available to choose any of the heating methods.
