Product details

Product Introduction

Yongjie twin screw extruder consists of two intermeshing, co-rotating screws mounted on splined shafts in a closed barrel. Resulting from a wide range of screw elements and barrel designs, various combination of screw profiles and process functions can be set up regarding to process requirements. Therefore, a twin screw extruder is able to ensure transporting, compressing, mixing, cooking, shearing, heating, cooling, pumping, shaping, etc. with high level of flexibility and ability to fully mix the compounds.

SJSL20 twin screw extruder is the smallest plastic pelletizing line we produce, which has a screw diameter of 21.7mm. It is perfectly designed for industrial production trials and lab experiments. We specifically designed it to be compact so that it can fit into tight spaces. It is safe and easy to operate with a Siemens PLC controller. As a standard, the SJSL20 twin screw granulator is equipped with water strand cooling pelletizer, but we also produce it with air cooling strand pelletizer. Those two cooling methods enables the SJSL20 extruder to produce a wide variety of polymer and polymer compounds (please see ‘Product Applications’ below).

Frequently Asked Questions (FAQ)

A.How can I be sure if your extruder can produce my material smoothly before I place the order?

We always welcome you to visit our factory, and if you can send us your raw material, we will perform free live trials with you so that you can see the end results of the plastic granules. 

B.What if I need to replace some parts of the machine due to wear and tear?

When you purchase our extruder, there are free spare parts for you to start with. We always recommend our customer to purchase some spare parts for the parts that are constantly under wearing (such as screw elements and pelletizer knives, etc). However, if you happen to run out, we always have spare in our factory and we will send them to you via air freight so that it does not disturb your production.
