● High life gear box; Wear resistant alloy screw bushing: Screw service life > 22000 tons(132*2)/40,000 tons (155*2),bushing service life >50000 tons(132*2)/60000tons(155*2), gear box free warranty 30000 hours;
● High-precision forging double jacket for expansion chamber. Sufficient strength to prevent jacket deformation or wear sleeve loosening. Enable to heating or cooling.
● Overload protection clutch is equipped to ensure the stability, safety and reliability of driving.High precision I gears, imported high quality bearing with oil seal, advanced gear box design and processing control technology.
● Equal clearance and self-cleaning double screw device can effectively reduce material residues in screw of machine barrel. Convenient for machine barrel cleaning.
● Removable wear-resistant bushing ofspecial material. Greatly reduce the cost of use.
● The shear force can be effectively controlled to ensure that the curing time of all materials in the expansion chamber is consistent with particle expansion coefficient.
● Effectively distribute reasonable shear force in different areas of the extrusion chamber. Effectively improve the output in the premise of high quality.
● Turbulence discharge device makes extruded feed more pleasing to the eye. The output of small-hole diameter mold can be increased by 30%-40%. The shape is uniform and stable.
● The automatic control system simplifies the operation and reduces the labor intensity. It makes all data recorded and the influence of operators on the quality of expanded products is minimized.
