Publish Time: 2025-05-28
With the increase of environmental awareness and the growth of demand for resource recycling, the plastic recycling industry has ushered in unprecedented development opportunities. In this context, EPE granulator, as an important equipment for processing expandable polyethylene (EPE), expandable polystyrene (EPS) and ethylene-vinyl acetate copolymer (EVA), is gradually developing towards automation and intelligence. Modern EPE granulator not only has efficient crushing and granulation capabilities, but also integrates automatic crushing, screw extrusion, motor automatic screen changing, water cooling and automatic pelletizing devices, forming a complete set of automation solutions, which greatly improves production efficiency and product quality.Automatic crushing system: realize efficient raw material pretreatmentThe first step of EPE granulation is to crush the waste materials. The traditional manual crushing method is inefficient, labor-intensive, and easy to cause raw material waste. The modern EPE granulator is equipped with a fully automatic crushing system, which can quickly crush large pieces of EPE, EPS or EVA waste into small particles, providing uniform raw materials for subsequent processing. The system uses high-strength blades and intelligent control technology to automatically adjust the speed according to the hardness of the material, ensuring a stable and efficient crushing process while reducing energy consumption and noise pollution.Screw extruder: Improving the quality of melt plasticizationThe raw materials after crushing enter the screw extruder system. This is the core link in the entire granulation process, which is mainly responsible for heating, melting, mixing and conveying plastic particles. The advanced EPE granulator adopts a high-torque motor to drive the twin-screw structure, which has good mixing effect and stable output performance. In addition, the temperature control system is accurate to ±1℃, ensuring that the raw materials are fully plasticized at the optimal temperature, avoiding material degradation problems caused by overheating, thereby ensuring the physical properties of the final product.Motor automatic screen changing system: ensuring continuous production stabilityDuring long-term operation, impurities may be mixed in the molten plastic, affecting the quality of the finished product. For this reason, the modern EPE granulator is equipped with a motor-driven automatic screen changing device, which can replace the filter screen without stopping the machine, effectively remove impurities and maintain stable melt pressure. The system is controlled by a PLC program, setting the screen change time interval or automatically triggering according to pressure changes, greatly reducing manual intervention and improving the continuity and stability of the production line.Water cooling system: precise temperature control to prevent material deformationThe molten plastic coming out of the extruder needs to be quickly cooled and shaped to facilitate subsequent pelletizing. The traditional air cooling method has a slow cooling speed and is prone to cause pellets to stick or deform. EPE granulator generally adopts an efficient water cooling system, which quickly cools the melt pipe through circulating cold water, so that the plastic can be solidified and formed in a short time. The system is equipped with a constant temperature control module, which can adjust the cooling intensity according to the characteristics of different materials, ensure the regular shape of the pellets, smooth surface, and improve the yield rate.Automatic pelletizing device: achieve high-quality pellet moldingPelletizing is the last step in the EPE granulation process, which directly determines the size and shape of the finished pellets. The automatic pelletizing device uses a high-speed rotating tool with a variable frequency speed regulation system, which can flexibly adjust the pellet length according to user needs and adapt to different uses. After cutting, the pellets are separated by a vibrating screen and enter the packaging link. The whole process does not require manual operation, which not only improves production efficiency, but also reduces quality problems caused by human errors.System integration and intelligent control: Towards a new height of Industry 4.0In order to further improve the automation level of EPE granulator, many manufacturers have integrated the entire production line into a unified intelligent control system. Through the touch screen interface, operators can monitor the operating status of each component in real time, adjust process parameters, and set up fault warning mechanisms. Some high-end models also support remote communication functions, which can view data and remotely control through mobile phone APP or PC platform, truly realizing the "unattended" intelligent manufacturing mode.The automation solution of EPE granulator not only represents the direction of technological progress in the plastic recycling industry, but also brings significant economic and social benefits to enterprises. It integrates multiple modules such as automatic crushing, screw extrusion, automatic screen changing, water cooling and automatic pelletizing, realizing the full process automation from raw material input to finished product output, greatly improving production efficiency, product quality and resource utilization.
