PVC Powder Plastic Extrusion Equipment Conical Twin Screw Extruder
1.introduction of equipment
This machine is mainly used for extruding PVC powder material
SJSZ conical twin screw extruder have advantages such as forced extruding, high quality, wide suitable range, long working life, small cutting rate speed, not-easy decomposition of material, good plasticized characteristics of calendaring, straight shaping of powder material and others. It is equipped with AC governor, automatic control temperature, vacuum exhaust and other devices. the line is suitable for production of pipe, plate and special-shaped materials.
The screw and barrel is made of high quality 38CrMoAlA alloy steel,the surface of screw and barrel is done nitriding treatment,the thickness of nitriding is 0.5-0.8mm,the roughness degree of barrel inner wall Ra≤0.4um ,the hardness of barrel ≥950HV,It has high hardness,anti-wear and anti-rust etc advantage.
This machine adopt high strength hard gear face gear box,the body adopt bevel wheel driving,gear is made from 20CrMoTi and it is treated by cementite and grinding,the distribution box is made from 38CrMoALA and is treated by nitriding,the shaft is made from 40Cr.the distribution adopt SKF bearing.The force lubricating system and force cooling system is equipped.The gear box have advantages of little size,beautiful appearance,high precision,high strength,long working life and low noise etc.
