The Characteristics and Maintenance Methods of Two-screw Extruder

1. The characteristics of two-screw extruder


The two-screw extruder has adopted computer and electronic control technology, so that the process parameters of the entire extrusion process can be detected online and can be controlled by a microcomputer. For example: the ratio of various raw materials, the temperature of each section of the fuselage, the pressure and temperature of the melt, the current and voltage of the motor, etc., which are very conducive to the stability of process conditions and the accuracy of products.


The specialization of the two-screw extruder can make it possible to arrange fixed-point production for each system module component and purchase it globally, which can ensure the quality of production, speed up capital turnover and reduce costs; its modular production can shorten the lead time of new products. Research and development cycle, adapt to the special requirements of different users, and strive for a larger market share.


The high efficiency of the two-screw extruder is mainly reflected in low energy consumption, high output and low manufacturing cost. In terms of function, it is not only used for extrusion molding and mixing processing of polymer materials, but also for building materials, food, ceramics, packaging, feed, pulp, etc.


2. The maintenance method of two-screw extruder


The staff maintains the two-screw extruder according to the process, so that the equipment can give full play to the more use value, and at the same time create more profits for the company. The maintenance of plastic extruders is the same as our own maintenance. We need to use careful and appropriate methods to extend the service life of the equipment.


The staff should often apply grease to the parts of the two-screw extruder. Lubricating oil is created to assist the operation of the company's equipment parts. This type of grease reduces the damage of the parts, improves the service life of the equipment parts, and ensures the smooth operation of the equipment.


If the equipment stops working, the staff should ask the merchant's after-sales service to deal with it, and do not repair it by yourself if there is no condition. Only professional maintenance personnel can repair the device without damaging it. Therefore, the staff should pay more attention to this point.


To maintain the two-screw extruder, the first thing to do is to ensure that the equipment is clean every day. After a day of production and operation of the equipment, there will be a lot of dust and waste inside the equipment manufacturing, so the staff should habitually clean up the system garbage for the equipment to ensure the cleanliness of the equipment.
