The advantages of double-screw extruder Jinan Dayi Extrusion Machinery will answer for you. The advantages of twin-screw extruder are as follows:
1.Double-screw extruder can intuitively understand the wear of wearing parts. Because of the convenience of opening, the wear degree of threaded elements and barrel liners can be invented at any time for effective maintenance or replacement. The pressed products will not be found when there are problems, resulting in unnecessary waste.
2.In order to reduce the production cost, it is often necessary to change the color when making color masterbatch. If the product needs to be replaced, please open the open processing area within a few minutes. In addition, the mixing process can be analyzed by observing the melt curves on all screws. At present, the general double-screw extruder needs to use a large amount of cleaning materials to clean the machine during color change, which is time-consuming, costly and waste of raw materials.
3.The double-screw extruder is easy to open, so it can observe the wear degree of the threaded elements, the inner sleeve of the barrel and other components at any time, so as to replace them timely and effectively, and avoid the waste of products caused by the damage of the components.
In addition, when performing mechanical maintenance, the heating and cooling systems of the ordinary double-screw extruder usually need to be removed first. When twitching the screw, the split double-screw extruder can only lift the upper part of the barrel by removing the necessary bolts and turning the turbine case handle device to open the barrel for repair. It not only saves time and reduces the labor intensity of maintenance workers, but also reduces the production downtime caused by equipment wear. Through the observation of the development trend of double-screw extruder, we can see that this field is currently developing in the direction of high torque, high speed and low energy consumption. For example, the productivity improvement brought by high speed is especially reflected in the split double-screw extruder, which makes it more suitable for producing and processing high-viscosity and heat-sensitive materials.
