Plastic Granulator Machine for PP LDPE HDPE Recycling

塑料造粒机 also called plastic granules making machine. It is the equipment to melt extrude waste PP(polyethylene) or PE(polypropylene) chips so as to make plastic granules. The main engine of the granulator is an extruder, which consists of an extrusion system, a transmission system, and a heating and cooling system. Broken, cleaned, and dried plastic can be directly put into the extruding machine. Then the extruded plastic strips usually need to be cooled in a cooling tank and cut into pellets by a pellet cutting machine. The plastic film pelletizing machine is an important part of the plastic recycling plant. It’s beneficial for vigorously developing renewable resources and turning waste into treasure.

Applicable material for recycling granulator

The design of the plastic granles making machine allows it to efficiently process a wide range of waste materials into pellets. For waste plastics we divide them into post-consumer and post-industrial plastics, both of which can be processed in our recycling machines.

Post-industrial recycling materials: In order to save on raw material costs and to realize a circular economy, many plastics producers like plastic bag manufacturers recycle their trimmings and then continue to process the pellets they produce into plastic products. These post-industrial plastics include HDPE/LDPE bag cut-offs, film-on-rolls, defective film and bag products, printed zipper bags, defective HDPE PVC pipes, PP/HDPE/LDPE regrinds, HDPE soft/rigid irrigation pips, etc.

Post-consumer recycling materials: All used and discarded plastic products such as used plastic bottles, plastic bags, abandoned meters, car parts, food containers, chemical drums, plastic pallets, PP ropes, plastic lumps, jerry cans, cosmetic tubes, bubble wraps, laminated/multi-layer films, flexible packing materials and so on.

塑料造粒机出售

作为主机的 plastic granule production line, the equipment applies to a variety of materials pelletizing. The appearance of the granulators for handling different materials are similar, but not the same. Their internal components need to be adjusted according to the specific material, such as the diameter of the internal screw, the distance between the screw and the barrel wall, and the length of the screw.

Therefore, one adjusted machine corresponds to one kind of material. The adjusted equipment is more suitable for the property of your raw material. So you can get in touch with us to get more detailed information by telling us what material you want to pelletize. Besides, we support customization services according to your specific recycling requirements.

机器结构

塑料造粒机结构由减速机、加料口、加热装置、压榨室、出料口、螺旋压榨机、模头、底座等部分组成。

这 减速器 是硬齿面减速机。作为塑料挤出机的关键部件，其质量非常重要。目前市场上常见减速机的质量排名为老式蜗牛减速机<普通减速机<半硬齿面减速机<硬齿面减速机。

主要有两种类型 模头 用于塑料挤出、电动模头、液压模头。液压模头滤网可在不停机的情况下更换。对于杂质较多的物料， 液压 一种更合适。但成本也较高。塑料造粒机的型号主要按螺杆直径来划分。螺杆材质为45#钢、40CR、38CRSI。塑料造粒设备的型号主要根据螺旋压榨机的直径来划分。根据塑料加工特性可提供镀铬、氮化等工艺定制服务。

The heating system of the LDPE/HDPE granulating machine

塑料挤出机的加热方式分为铸铝加热圈、石英管加热圈、陶瓷加热圈、电磁加热圈。其中，加热效果最好的是电磁加热。铸铝加热圈加热需要30-40分钟，电磁加热圈需要15-20分钟。电磁加热可以快速升高温度。并且恒温效果好，运行稳定。但它不适合加工泡沫材料。加热方式应根据原料和最终产品的颜色来考虑。

塑料造粒机的工作原理

1. Turn on the HDPE/PP/PVC granulaing machine. Looking at the machine whether there is abnormal sound or vibration. If not, put it into use.
2. 注意对塑料造粒机进行预热，使塑料熔化。如果温度太高，熔化的塑料会变黑。而低温则不能熔化塑料。
3. 最好配备自动喂料机将塑料碎片喂入塑料造粒设备，因为塑料薄膜材料很轻，不易喂料。
4. 将塑料薄膜碎片熔化并压入主机，然后随螺杆推入辅机。最后，熔化的材料将以塑料条的形式从辅助发动机中挤出。
5. 在模头下方放置冷却槽，使热塑条在槽内冷却并成型。

塑料造粒机设备使用时要注意什么？

• 机器内部不应有金属残留物或细沙。请勿在进料口周围放置金属物品或其他物品，以免落入机器中，以免损坏塑料颗粒机，造成堵塞或破坏。
• The operator had better receive actual training about how to operate the granulating machine. In addition, they should also learn the structure of the equipment and operating procedures.
• 控制冷却水箱的水温。因为如果温度太低，塑料条就会断裂。虽然高温不能使塑料条冷却并良好成型，并且条可能会粘住。
• 熔化的塑料在进入塑料颗粒切割机之前应均匀地挤出成条。不均匀的条带可能会损坏塑料颗粒切割机。如果挤出的条材很薄或断裂，模头的孔可能会被杂质堵塞。所以需要更换过滤网。

Parameters of HDPE granules making machine

We have 7 models of granulator machines for you to choose from. The biggest difference between the 7 machines is the output. The output is 150kg/h, 180kg/h, 200kg/h, 300kg/h, 350kg/h, 380kg/h and 420kg/h respectively. Similarly, different output corresponds to different prices. If you have a large plastic recycling plant, we suggest you buy 380kg / h or 420kg / h machines. We will also give you the best price. Secondly, you need to consider your plant area and machine size. As you can see, larger production means larger size. For example, the size of a machine with an output of 150kg/h is 2.4 * 0.7 * 0.7, while the size of a machine with an output of 420kg/h is 3.8 * 102 * 1. If your plant area is too small, it is not suitable for oversized machines, or you can adjust the size of your plant.
