Characteristics of twin screw extruder
The screw arrangement are adopted “toy bricks” principle, which assembly according to different machine L/D, different feeding way, different barrel and screw combination, different screen changing and cutting way, different electrical control mode, etc. it meets the features of material and technological process. Give consideration to the plastic universality commonality and appropriability.
Yongjie laboratory mini extruder SJSL20 is widely used among our customers of universities, research center, and factory R&D department for the testing of formula, compounding etc.

Interlock control
1). The extruder motor is set up the current overload to achieve chain shutdown protection with electric control cabinet.
2). The control system of main machine motor is interlocked with control system of feeder motor as a way of protection mutually.
3). Transmission gearbox and lubrication system are interlocked for protection.
4). The extruder is set up the pressure overload to achieve chain shutdown protection with electric control cabinet.
5). The main motor is connected with the nylon pin of transmission gearbox so as to cut off the nylon pin when torque is overload.
