The screw speed of the extruder should be controlled at the appropriate amount of the maximum extrusion amount Depending on the process and materials, if the materials allow, it works best at about 90% of the speed and about 90% of the current, which can maximize the use of the machine's production capacity and ensure the machine's life. If some materials are more difficult, then the current c

The theoretical output of single screw: Theoretical output Q=0.06 * (screw pitch-screw width) * screw groove depth at the discharge end * (screw diameter-screw groove depth at the discharge end) * pi * melt density * speed. Among them, the screw pitch, screw rib width, screw groove depth at the discharge end, screw diameter are in centimeters; the speed unit is how many revolutions per minut

Method for adjusting screw gap of counter-rotating conical twin-screw extruder Specific steps 1) Install the front and rear supports on the barrel and put it on the mainframe together with the screw (installed in the barrel). First, do not install the locking nut. Shake the front support manual rocker to move the barrel in the direction of the distribution box. Look at the barrel stop

Commissioning and operation of 65 conical twin screw extruder. The test run of the machine must be operated by a person who is familiar with the process, so that measures can be taken when an accident occurs during the test run to prevent the accident. (1) Check whether the 46th gear oil in the reduction gearbox and distribution gearbox has reached the oil mark. If not, the oil should be add

How to increase the life of conical twin screw extruder Compared with the general single-screw extruder and parallel twin-screw extruder, the counter-rotating conical twin-screw extruder (hereinafter referred to as "cone twin") has its common feeding area, large shrinkage ratio, and the screw is in the longitudinal direction The shearing and mixing power of the material in the horizontal and hori

The principle of twin screw extruder 　　From the point of view of motion, there are co-rotating, counter-rotating and non-meshing types in twin screw extruders. Co-rotating twin screw extruders are available in low speed and high speed. The difference lies in the planning, operating characteristics and application areas of the two extruders. The former is mainly used for profile extrusion, while t

Feeding height of feeder 　　 There are some other factors to consider: Under the ideal condition of the feeder's blanking height, the feed screw should be installed as close as possible to the top of the side feed opening to reduce the blanking height. If some loose material flows through the air, then it may become filled with air, so that its false density is greatly reduced after falling.

Add heat insulation gasket between the feeding section and the second section 　　 Rod extruder is a commonly used equipment for waste plastic processing and modification. Today we introduce some small details that can improve the performance of twin-screw extruder. These details include three aspects: equipment modification, equipment maintenance and operation standards. Equipment modification: Th
