SJ series high-speed single screw extruder

SJ series high-speed single screw extruder

Two stage overall design enhances plasticizing function, ensuring high-speed and high-performance extrusion. Special barriers and BM type comprehensive mixing design ensure the mixing effect of materials. High shear and low melting plasticizing temperature ensure high-performance extrusion of materials.
Design concept
*High speed and high-yield extrusion based on high quality.
*The design concept of low-temperature plasticization ensures the extrusion of high-quality products.
*High torque output, extra large thrust bearing.
*Gears and shafts are made of high-strength alloy steel, carburized and ground treated.
*High hardness, high smoothness, ultra-low noise.
*The hopper type automatic dryer prevents moisture from the material.
*Automatic feeder, effectively reducing labor intensity.
*Optional weighing and feeding device. Control the weight of the product.
*Automatic PLC intelligent control can achieve linkage between main and auxiliary machines.
*Easy to monitor human-machine interface for easy understanding of processing and machine status.
*The control mode (temperature control instrument) can be replaced as needed.
*The material is 38CrMoAL/A nitrided treatment, wear-resistant.
*Strict temperature control accuracy, combined with wind and cold water cooling.
*Unique inlet design with perfect water cooling device.
*Professional irregular trapezoidal groove design liner.
*The screw cylinder with a grooved feeding bottom sleeve has enhanced feeding function, providing a guarantee for high-speed and high-yield extrusion.
