The feeding system is the input end of the co-rotating parallel twin-screw extruder. Whether it works normally, stably, and on the ground will directly affect the performance of the co-rotating parallel twin-screw extruder. It is mainly reflected in the following three aspects:
(1) Feeding amount
The size of the main feeding amount affects the saturation of the whole machine. The feeding amount in the multi-channel feeding system not only affects the saturation of the whole machine, but also affects the formula of the material. Therefore, the matching of the feeding amount with the host and the nature of the feeding amount are very important.
The feeding system of the co-rotating parallel twin-screw extruder must work stably to ensure the normal operation of the co-rotating parallel twin-screw extruder and the product quality. The stability here mainly refers to the rotational speed. A stable rotational speed can ensure a stable feeding amount, so the electronic control system generally outputs at a constant torque.
(3) Adaptability to materials
The co-directional parallel twin-screw extruder has many types of materials and different performances. According to the appearance, there are pellets, powders, mixtures, and a variety of additives. It is impossible for the same feeding system to achieve stable and ground feeding of each material. Therefore, it is difficult to improve the adaptability of the feeding system of the co-rotating parallel twin-screw extruder to the material, which is also a development direction.
