I. Model Meaning
SJSZ: Double screw (S), conical (J), counter-rotating (Z)
80: The diameter of the screw's lower end (feeding end) is 80 mm
156: The effective working length of the screw is 156 mm
II. Core Technical Parameters
Main machine power: 55 kW (variable frequency speed regulation)
Production capacity: 300–450 kg/h (mainly hard PVC)
Screw material: 38CrMoAlA nitrided steel / bimetallic alloy (resistant to HCl corrosion)
Length-to-diameter ratio (L/D): approximately 18:1 (conical design)
Temperature control system: multi-zone independent PID, temperature difference ≤ ±2℃
Shearing method: surface heat shearing (air-cooled)
Particle specifications: Φ3–4 mm round cakes / cylindrical
III. Equipment Composition (the entire line)
High/low speed mixing unit: PVC powder, stabilizer, plasticizer, filler premix
Screw feeding machine: automatically conveys the mixed material to the main machine
SJSZ80/156 conical double main machine: plasticizing, melting, extruding core
Hot cutting die head: porous die head + rotating cutter
Three-level pneumatic conveying cooling system: particle cooling, conveying, screening
PLC control cabinet: automatic control of temperature, speed, pressure
IV. Main Applications
Hard PVC (UPVC): pipes, profiles, plates, granulation
Soft PVC: cable material, hoses, artificial leather, transparent granules
High filling / modified PVC: calcium carbonate, wood plastic, recycled material granulation
Advantages: low shear, decomposition prevention, good exhaust, dense particles without air pores
