换网装置在大型挤压机上的应用

Application of screen changer for large-scale extruder

近些年挤压造粒机组快速发展,单台套机组的产能逐渐提高,自动化程度越来越高。为满足挤压造粒机组的要求,换网装置的结构及操作都进行了改进优化。阐述了换网装置在大型挤压机上的应用,换网装置的发展工作原理及目前常见的几种形式,并进行横向对比。

In recent years,the rapid development of extruded granulation units has gradually increased the capacity of single set of units,and the degree of automation increased too.In order to meet the requirements of extruding granulator,the structure and operation of the screen changer are improved and optimized.This paper expounded the application of screen changer in large-scale extruder,the working principle of screen changer,several common forms at present,and makes a horizontal comparison.
