2. Features of extruder
- 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.
---.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
- 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
