塑料颗粒机在废旧塑料的加工和再生颗粒的制备中发挥着至关重要的作用。让我们深入了解这台机器的操作和性能，解决您可能好奇的问题。
Different Materials On A Single Pelletizing Line?
造粒机的设计并不通用。不同类型的塑料具有不同的熔融特性和挤出要求。因此，不同物料使用同一条塑料造粒线可能会导致温度、压力等参数不匹配，影响整体生产效率。因此，一般不建议在同一条生产线上加工不同类型的塑料。
There are some other common problems when it comes to plastic pelletizing lines. Taking the plastic recycling granulating line that processes one tonne of plastic per hour as an example, the power consumption for processing one tonne of plastic is about 500 degrees, while the whole production line can be completed by only 3-4 workers. Our plastic recycling granulating line not only ensures high production efficiency and product quality but also makes the production process more energy efficient and labor costs more economical.
Temperature Settings For Pelletizing Machine
For the pelletizing of PP and PE, temperature control is paramount. Typically, the temperature needs to reach 240 degrees, and the plastic pellet machine’s operating temperature can go as high as 500 degrees. This ensures that the plastic fully melts at high temperatures, facilitating the subsequent extrusion process.
Diameter Of The Line Produced By The Die Head
造粒过程中挤出线的直径通常在3.2mm左右。这个尺寸是通过塑料颗粒机的设计和调整来实现的，直接影响所得颗粒的规格和用途。
What Is The Working Principle Of Pelletizing Machine?
The working principle of the plastic pellet machine is based on the processes of high temperature and screw extrusion. Initially, the machine needs to be preheated to bring the entire system to the appropriate operating temperature. Then, plastic raw materials are fed into the machine. Through the force of the screw extrusion at high temperatures, the plastic melts and is extruded, ultimately forming pelletized plastic.
Problems With Die Head Changing Screens
有客户问回收造粒机模头多久需要换一次筛网。屏幕可以重复使用吗？
模头净变化的频率取决于材料的清洁度。如果材质比较脏，就需要经常更换。然而，对于更清洁的材料，一周左右就足够了。塑料颗粒机的模网可以通过焚烧筛网并清洗后重复使用。
How Are Plastic Pellet Machine Models Differentiated?
造粒机型号通常根据螺杆内径进行区分。螺杆内径的大小直接关系到造粒机的生产能力和适用范围。
通过了解塑料颗粒机的工作原理和关键参数，我们深入了解这些设备在废旧塑料回收领域发挥的关键作用。从材料选择到温度控制，每个方面都至关重要，影响着最终再生颗粒的质量和应用。在使用造粒机时，科学合理的操作，加上定期的维护保养，是保证生产效率和产品质量的关键因素。
