Principle and method of cooling the extruder head
Jan 23, 2025| The extruder head is to flush the high-temperature and high-pressure materials into the low-pressure chamber, and instantly convert the water into steam, so that the heat generated during the instantaneous expansion of the materials needs to be dissipated through the heat dissipation of the head. Therefore, during the production process, the extruder head will be continuously subjected to high temperature and high pressure. After a certain period of time after working, the head will become abnormally hot, which will affect the normal operation of the equipment. In order to ensure the normal operation of the extruder, the head needs to be cooled.
| Model | production capacities | Power | weights | sizes |
| 40 | 40-50kg/h | 5.5KW | 310KG | 1300*1200*1100 |
| 50 | 80-100kg/h | 7,5 kW | 330KG | 1350*1100*1200 |
| 60 | 120-150kg/h | 15kW | 360KG | 1350*110*1200 |
| 70 | 180-200kg/h | 18,5 kW | 410KG | 1500*1360*1250 |
| 80 | 200-240kg/h | 22kW | 460KG | 1500*1450*1250 |
| 90 | 400-500kg/h | 30KW | 800KG | 1650*1450*1300 |
| 135 | 500-700kg/h | 55kW | 1200KG | 1800*1550*1500 |
In order to better reduce the temperature of the head, a cooling device can be installed on the equipment. In general, the cooling device is mainly water-cooled. By arranging a water cooler at the head or adding water to the channel to dissipate heat, the temperature of the head is effectively reduced to ensure stable and dynamic operation.
During the operation of the extruder, the adjustment of the processing speed is also an effective cooling method. By evenly adjusting the processing speed, the temperature of the extruder head can be made more stable, thereby reducing the occurrence of excessive head temperature.
