Screw local configuration design

Screw local configuration design:

一，Feed section: the purpose of feeding throat is to smoothly and flexibly add various materials, generally using large pitch、forward thread conveying components, and large screw groove depth thread components to obtain greater feeding capacity and conveying capacity.

二，Local screw structure for compressing materials:

The purpose is to compact and improve the filling degree of granular materials in the spiral tank, so as to promote the melting and plasticization of materials.

There are two methods to realize: 1, change the thread pitch in sections, make it from large to small. 2, change the thread  pitch gradually.
