2. Features of extruder

(1) Barrel

• euro-style rectangle barrl, reflux refrigeration channel is optimized and disposed,which makes temperature difference in D areas smaller.
• innovated design of heater tightened style insures high efficiency of heat transfer and high longevity of heater.
• the material is used high quality nitrided steel ,corrosion proof or antifriction with correspounding process.

(2) screw

---.the screw is made of high tool steel 38 CrMoALA or W6Mo5Cr4V2 by special heat-treatment , which is

possessed with high corrosion-resistat and high functions

(3)metering feeders

• various metering feeders --- single screw ,twin screw ,hollow screw,forced-feeding, side- feeding.

(4) new-style gear transmission system

• new-style project of parallel three-axises driving makes the conve axis,convey
• chain,decelerate and torque get together ,which keep it compact ,and the key bearings are imported
• soakage and spraying lubriation integrate smoothly
• technics,strengthening of tooth face,so they can ensure high torque,high precision and low noise
• the selecte material of drive components is dainty,including super intention alloy cementiteing steel,cementiting and grinding.

(5) electric control cabinet

• frame structure control cabinet
• imported electrical elements
• imported temperature control system
• imported driving system
• interlock and multi-protection
• adopting imported PLC(OMRON or SIMES) to achieve optimized process control. stronger function,steady performance and much higher accurancy
• it can be also accomplished full-set link-lock protection,trouble safeguard,fault alarm cluing and so on
• operation interface on touching screen is visual and marked ,which is brief and easy to use.

(6) pelletizing system

---.various modes of pelletizing,such as water-cooling strand,air-cooling pelletizing,water-ring pelletizing,under water pelletizing
