                        The structure of Zhoushan screw can generally be divided into three sections. The front section belongs to the feeding section. The material in the hopper is added to this section to compact it. The second stage is the compression stage, this stage is to continue to compact and not enter the molten state. Then there is the third stage of field transformation, in which the main part will become the state of viscous flow.

                        There are several reasons for the wear of Zhoushan screws.

                              1. Damage of twist-off nature. The situation that the screw is twisted off is generally due to thinking, irregular operation or because of a failure of the control system. This situation generally occurs in the feeding section because the strength of this section is relatively low.

                              2. The screw is worn. Because of the friction generated by the machine, the screw will have surface wear after a certain number of years of use, and the efficiency of the screw will become low after the screw is worn. If it is serious, it will directly affect a state of its work.

                              For the twisted screw, we will perform a screw positioning, and weld the place that is more prone to problems to avoid its misalignment. It needs to be corrected during welding, and there is no way to correct it after completion.

                              If it is worn, it is usually in the third stage. The repair process is actually relatively intermittent. It is good to fill in the surface of the worn place.
