①Screw diameter: refers to the outer diameter of the screw, in mm. For variable diameter or conical twin screws, this is a variable and should indicate which end diameter. The screw diameter of the twin-screw extruder is 28~340mm. The larger the diameter, the greater the throughput of the characterization device.
②Screw length-to-diameter ratio: refers to the ratio of the effective length of the screw to the outer diameter of the screw. For the integral twin-screw, the aspect ratio is fixed, generally 7~18; for the combined twin-screw, the aspect ratio is variable, and some can even reach 36:1.
③Screw steering: divided into co-rotation and counter-rotation. The co-rotating twin-screw extruder is mostly used for mixing materials, and the counter-rotating twin-screw extruder is mostly used for extruding products.
④Drive power: refers to the power of the motor that drives the screw, in kW.
⑤ Torque on the screw: The twin-screw extruder is under a large torque load. In order to characterize its bearing capacity and protect the safe operation of the extruder, the torque that the screw can withstand is generally listed in its specification parameters, which cannot be exceeded during work. The unit is kg.m.
⑥The bearing capacity of the thrust bearing: The thrust bearing is an important part in the twin-screw extruder, and this index is generally given in the product specification.
⑦Heating power and number of heating segments: The unit of heating power is kW.
⑧Output: the unit is kg/h.
