SAT Twin Screw Extruder

With 10.3Nm/cm3 specific torque, it is able to achieve more delicate processing task, precise process control can meet complicate and sophisticate processing purpose. Better dispersion, more accurate temperature control and higher throughput have been integrated and optimized further.

Our SAT Series is Co-rotating Twin Screw Extruder, it’s our most popular twin screw extruder. It authentically explains one-for-multiple. More powerful gearbox, more precise screw elements endow SAT more flexible processing range and wider operation window. We also provide individual solution according to customized requirements. Variety of modular screw elements, barrels, melt filtration and pelletizing system will get the most out of your investment.

The perfect concept of the split-transmitting principle has been successfully applied in USEON-patented gearbox with the digital online monitoring system; each gearbox is assembled with precise positioning for torque balance.

High Torque Gearbox

SAT Twin Screw Extruder High Torque Gearbox

Our SAT75 gearbox can install maximum 280kW with screw speed 600rpm.

Total Torque of the gearbox=9550x280KW/600rpm=4456N.m
The center distance between two output shaft (D) is 6cm
Specific torque=T/(2*D^3)=4456/(2*6*6*6)=10.3

Heating System

SAT Twin Screw Extruder Heating System

Instead of traditional casting heater (outside the barrel), we use cartridges heater (made in Germany) inside the barrel, it will save energy and Polymer will be melt mostly by heating, not kneading elements, so the working life of screw and barrel is longer and the quality of the compounding is better.

Cooling System

SAT Twin Screw Extruder Cooling System

With two input and output on each barrel, more uniform cooling and fast cooling.

Supporting Frame

SAT Twin Screw Extruder Supporting Frame

The supporting point of traditional barrel is in the underneath. When heated, its thermal expansion is upward with the value 0.2~0.5mm (difference up to the size of extruder), and uneven gaps in the upper and lower between screw and barrel.

The supporting point of barrel of SAT twin screw extruder is in the middle, When heated, its thermal expansion is upward and downward uniformly, ensuring the center height is on the horizon and the constantly even gaps in the upper and lower between screw and barrel.
