Do you know about second-hand plastic extruders?
In the second-hand plastic extruder equipment, the second-hand plastic extruder is usually referred to as the main machine, and the matching follow-up equipment plastic extrusion molding machine is referred to as the auxiliary machine. After more than 100 years of development, the second-hand plastic extruder has changed from the original single screw to a variety of models, such as twin screw, multi-screw and even no screw. Second-hand plastic extruder (host machine) can be used with various plastic molding auxiliary machines, such as pipes, films, fixed materials, monofilament, flat wire, packing belt, extrusion net, plates (sheets), profiles, granulation, cable coating, etc. Supporting, forming a variety of plastic extruder molding production lines, can produce a variety of plastic products. Therefore, now or in the future, the second-hand plastic extruder molding machinery is widely used in the plastic processing industry. The main body of the second-hand plastic extruder is the extruder, which is composed of an extrusion system, a transmission system and a heating and cooling system.

Working principle of twin-screw granulator
After passing through the feeding port, the material is rolled into a ball and rolled forward along the screw groove under the action of the rotating screw. Due to the shearing, compression and stirring of the screw, the material is further mixed and plasticized, and the temperature and pressure gradually increase, showing a viscous flow state, and passes through the machine head with a certain pressure and temperature, finally obtaining the products of the required shape.
