PVC Carbon Black Nanjing two stage plastic extruder compounding pelletizing machine
 Two Stage Extruder ZL series, that’s two stage compounding extruder consisted of two parts. Mainly there are three types of two stage extruder combination: 1.Single screw main extruder machine-single screw submachine 2.Single screw main pelletizing machine-twin screw submachine 3.Twin screw main pelletizing machine-single screw submachine The first two types are widely used for recycled plastic granulating.  And the third type for heat-sensitive material like PVC, POM, XLPE etc. The twin screw extruder (SJSL-) at the first stage is to realize good shearing and compounding for material, and then the extrusion and pelletizing by YD single screw extruder (second stage). The new, scientific and advanced design and structure can avoid material decomposition caused by material overheating Application of Twin-Single Screw Extruder Carbon black master batch PVC cable, PVC transparent bottle and blood transfusion tube materials PE silicon hydride crosslink cable material, peroxide crosslink cable material Wood- plastic blending material Heat-sensitive polymeride  Quick details of machine Model:ZL75-180 Motor:132kw for sjsl75 twin screw extruder main machine, 90kw for YD180 single screw extruder sub machine Output:500-600kg/hour L/D: 36:1 for twin screw main machine, 7:1 for single screw sub mahine Speed governing: Inverter control speed; Revolutions: 0-500rpm; Reduction : Reduction ratio: i = 3:1; Transmission gear: Parallel tri-axial structure is combination of reduction and matrix. The gear is made of high quality alloy (20CrNi2Mo). It had been treated by cementation heat process, the precision grade can reach 6th. It guarantee the tooth surface is high speed, overloading, low noise and high torque. Drive bearing: The brand of axletree: Japanese NSK. Lubrication: Gear bearings in the gear box will be of oil immersed. There is hydraulic lubrication in the gear engagement and gear bearings. Cooling: Lubricated cooling adopts shell and tube cooler and circulated water cooling method.   Various model of our two stage extruder
