Tset Series Twin-Screw Co-Rotating Water Cooling Strand Pelletizing Extrude

What is filler masterbatch?
Filler masterbatch is composed of various additives, filler(example:CaCo3, Talc,Titanic,etc) and a small amount of plastic resin carrier,produced by mixer, twin screw extruder and pelletizing.In order to facilitate the operation during plastic molding.blowing process 120-1000kg/hr plastic single screw extrusion and pelletizing line.

SW series single screw extrusion and pelletizing system is a specialized and reliable system, it’s specially designed for recycling medium and large quantities of heavy regrind materials (> 300 g/l) such as PE, PP, PS, ABS, PA and PC etc. rigid plastic scrap. the material is transported directly into the extruder by a screw conveyor without being pre-cut or compressed. The rate of material feeding is controlled automatically by the load on the extruder motor. Solid foreign substances are filtered by a continuous melt filter available with or without backflushing system. It’s an efficiency and continuous system that makes rigid plastic into granules with gentle remelting, significant volatilization and impurities-filtration.

The particular advantage of our system is that no heating or other treatment of the material is necessary before extrusion. A clear and easy-to-use touch screen ensures a comfortable starting and stopping process and operation of the line. Our system comprises five machine sizes which together cover an output range of 120 – 1000 kg/h. Each machine can be equipped with degassing, high vacuum, backflushing filter and pelletizing systems (strand, water-ring or under-water: Depend on the type and quantity of the material.

1.The gearbox

· New-style project of parallel three-axises driving makes the convey axis, convey chain, decelerate and the torque assignment get together, which keep it compact, and the key bearings are imported.
· The select material of drive components is dainty, including super intension alloy cementiteing steel, cementiting and quenching, gear grinding technics, strengthening of tooth face. So they can ensure high torque, high precision and low noise.
· Soakage and coerce lubrication integrate smoothly. When the hydraulic circuit is over pressed, it alarms.

2.The feeding system

· Metering feeders are equipped with single screw, twin screw, hollow screw, forced-feeding, side feeding, liquid-adding system,etc.

3.Screw

· The screw elements and then kneading blocks are designed accurately, by precise processed, agile combination, with interchangeability, which can fulfill efficient self-cleaning, transmission, compounding, pressure-forming.
· The screw material is made of high tool steel 38CrMoALA or W6Mo5Cr4V2 by special heat-treament.

4.The barrel

· Eurostyle rectangle barrel, reflux refrigeration is optimized and disposed, which makes temperature difference in C areas smaller.
· According to the material and special techinics demands, the material of cylinder can use high quality nitrided steel, corrosion proof or antifriction with corresponding process.

5.The heater

· Innovated design of heater tightened style insures high efficiency of heat transfer and high longervity of heater.

6.Pelletizing

· Variou modes of pelletizing, such as water-cooling strand, air-cooling pelletizing, water-ring pelletizing, under water pelleting, etc
