Brief Description:The internal structure of a twin-screw chamber color masterbatch pelletizer largely depends on the design principles; it can be said that technical elements influence its internal structure. The internal structure, in turn, forms the basis for the external shape, meaning that the external form is an outward manifestation of the internal structure. This relationship is quite evident in the exterior design of box-type components.
Twin-screw chamber color masterbatch pelletizing machineExtrudable plastics are thermoplastics, which melt when heated and solidify again upon cooling. Therefore, heat is required during the extrusion process to ensure that the plastic reaches its melting temperature. So where does the heat for melting the plastic come from? Initially, the preheating of the feed by the floor scale and the mold heaters may play a role and are very important at startup. Additionally, the energy input from the motor, that is, the frictional heat generated inside the barrel as the motor overcomes the resistance of the viscous melt to turn the screw, is also an important heat source for all plastics, except in cases of small systems, low-speed screws, high-melt-temperature plastics, and extrusion coating applications.
In operation, it is important to recognize that the barrel heater is not actually the primary heat source, and its effect on extrusion may be less than we anticipate. The temperature of the rear barrel is more significant as it affects the meshing.
Twin-screw chamber color masterbatch pelletizing machineThe internal structure largely depends on the design principles, and it can be said that technical elements influence its internal structure. Moreover, the internal structure is the basis for the external form, in other words, the external form is the outward manifestation of the internal structure. This relationship is quite evident in the exterior design of box-type components.
In addition to the internal structure, there exists an inclusive relationship between the internal structure and the external form, with the external form sometimes being a design of the structure itself. Given that the primary work of industrial design is reflected in the appearance of the equipment, the structural and styling design of the exterior components are very closely related.
In a twin-screw color masterbatch pelletizing machine, the change in screw speed is achieved by adjusting the motor speed. The drive motor typically rotates at full speed of about 1750 rpm, which is too fast for an extruder screw. If it were to rotate at such a high speed, it would generate too much frictional heat and fail to prepare a uniform, well-mixed melt due to the excessively short residence time of the plastic. A typical reduction ratio should be between 10:1 and 20:1, with the first stage using either gears or pulleys, but the second stage uses gears and positions the screw at the center of the large gear. For some machines that operate at slower speeds, there may be three stages of reduction, with the final speed possibly as low as 30 rpm or even lower (with a ratio up to 60:1). On the other hand, some very long twin screws used for mixing can operate at 600 rpm or faster, thus requiring a very low reduction ratio and more intensive cooling.
