Why install a screen changer downstream of the melt pump?
The screen changer is used to filter foreign matter such as carbides and unmelted polymers in the molten polymer; it can prevent the quality of the product from degrading. In addition, the screen changer can also remove large solids that can damage the melt pump. Usually, the screen changer is only installed upstream of the melt pump to achieve the above two purposes. However, we recommend that when using Batte melt pumps, install a screen changer downstream to ensure the quality of the product while saving more than 30% of energy.
The screen changer is installed upstream of the melt pump
The screen changer is installed downstream of the melt pump
When the screen changer is installed upstream of the melt pump, the screen changer is a hindrance to the pressure. Therefore, the extruder itself must perform some pressurization; however, compared with the melt pump, the extruder increases The pressure capacity is relatively low. When it pressurizes the screen changer, the extruder will generate additional heat. In order to achieve the necessary outlet pressure, the extruder must increase the speed; this will increase the polymer temperature, while the polymer viscosity will decrease, and the volumetric efficiency of the equipment will be destroyed; at the same time, it will also lead to a reduction in energy efficiency.
By adjusting the position of the screen changer to the downstream of the melt pump, the melt pump can give full play to its pressurizing function; at the same time, the outlet pressure of the extruder can be reduced. While ensuring the energy saving of the extruder device, the temperature of the polymer can also be lowered and stabilized. However, the volumetric efficiency of the traditional melt pump is low, and it cannot effectively pressurize the downstream die and screen changer only by relying on it. Therefore, a screen changer is installed downstream of the melt pump. batte melt pump/ screen changer: info@battemachinery.com
