Product Description

Screw is the main working parts of the extruder screw by the thread part and part of the transmission device connected thread is composed of single head double head and compound thread three kinds of single head for filter glue, double head for extrusion modeling (uniform), compound thread that feeding end is single head thread (easy to feed) discharging end is double head thread
Pitch with isometric and variable pitch and screw groove depth is deeper and darker, generally for isometric range such as deep or not equidistant So-called isometric ranging from deep, that is, all equal thread pitch, thread groove depth decreasing since feed end So-called deep not equidistant, namely equal screw groove depth, and pitch from the feed end up gradually decreases The screw thread part of the working length and outer diameter of the screw ratio of length to diameter ratio
It is one of the important parameters of extruder, such as large length to diameter ratio in rubber extruder within walking long distance, is being squeezed from the shear mixing effect is big, and the sheet resistance is big, the consumption of power is more screw feed end of a screw slot volume and discharge end of a spiral groove volume than the compression ratio, which represents the sizing degree of compression may be in the extruder .
