Experts from the twin-screw extruder service provider Nanjing Jieente Electromechanical Co., Ltd. said that for the meshing early twin-screw extruder, be careful not to mistake the position of the two screws when loading the screw. If the material is added after the vehicle is added, the material will not be transported forward at the feeding port, the screw head will be on the machine head, and the current will increase. When such a situation occurs, stop immediately, remove the machine head, and reload in the correct position. . Before driving, check whether the circuit wiring of each part of the machine is correct; whether the cooling system of the barrel screw is normal and unblocked; whether the drive system is normal, whether the lubricating oil level is normal, whether the oil circuit is unblocked, whether the metering and exhaust system is normal; Whether the connecting bolts are tightened, etc.
Single screw granulator service provider experts said that for pellets, the feed should be metered to prevent overload; for powder, overflow feed can be used, pay close attention to whether it is overloaded. When driving, add a small amount of material and keep the balance of the feed. At this time, pay close attention to the torque gauge pointer. The main screw speed should be rotated at a low speed. When the material is extruded from the die and the traction device is introduced, the screw speed is gradually increased, and then the feeding amount is increased until the set value is reached.
Experts from Nanjing Jie Ente Electromechanical Co., Ltd. said that the feeding was stopped before stopping, and the screw of the main machine was running at a low speed to discharge the materials in the screw. For the counter-rotating twin-screw, when the standby head no longer has material discharge, remove the machine head, pull out the screw, clean the screw, the machine head and the barrel, and then assemble and reset, and use it for the next drive. If a special cleaning material is used, it is not necessary to pull out the screw for cleaning. Normally, maintenance and maintenance should also be carried out. If empty car operation is not allowed, the screw and barrel should not be worn. If the operation is not normal, stop immediately to check and repair; prevent metal or other debris from falling into the hopper.
