Analysis of cooling methods for extruders:
Jan 23, 2025| The cooling water circulation system of the extruder is one of the most common cooling methods. The system can be divided into two parts: the main system and the water supply system. The main system consists of an outlet pipe and a return pipe, while the water supply system consists of a water tank, a pump and a pipeline. This method has a good cooling effect, but consumes a lot of energy.
Air-cooled cooling is also a common method. An air duct is set in the extruder, and the hot air is blown out and the fresh air is blown in by the fan, which has a cooling effect. This method saves energy, but the cooling effect is not as good as the cooling water circulation system.
| 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 |
Increasing the heat dissipation area of the extruder is also a feasible cooling method. The temperature of the extruder can be reduced by increasing the number of heat sinks or increasing the area of the cooler. This method has a moderate effect, but the modification of the extruder is more troublesome, and it is necessary to pay attention to whether the performance of the modified machine is stable.
After the extruder is used for a long time, a certain amount of oil will be generated inside, affecting the heat dissipation effect. Therefore, it is necessary to clean the inside of the extruder regularly. An uncleaned extruder will reduce the heating efficiency and even make the machine unable to operate normally.
Using insulation material on the shell of the extruder can reduce the heat dissipation of the extruder to a certain extent. The cooling effect of this method is not very obvious, but it can avoid the instability of heat dissipation affected by ambient temperature.
