Ring Die Pellet Mills

NPM provides the latest and sophisticated pellet mill in China and binder not required. As a leading China pellet mill maufacturer, now we have two models, one is AKG420 and another is AKG508.

Specification of Model AKG420
Capacity: 1-1.5T/hr without binder, 100% saw dust basis.
1.5-2T/hr without binder, straws basis

Power: 0.75kw+1.5kw+0.75kw+90kw

Specification of Model AKG508
Capacity: 1.5-2.0MT/hr without binder, 100% saw dust basis.
2.5MT/hr without binder, agriculture straws basis.
Power: 0.75kw+1.5kw+0.75kw+115kw


1. Adopting aerodynamic technology & the current round principle: reduces the temperature in pelletizing chamber to around 90°C. As a result the machine can work well continuously.

2. Timing feeder can control the feeding speed to reduce the block ratio.
3. The body is more durable because we use spheroidal graphite cast iron.
4. Capacity increased after adding another force feeder made from stainless steel to increase the feeding spread area.
5. Improved U type screw conveyor. Adjustable feeding speeds allow continuous feeding without blockage.


6. Using the most famous brand of motors in China: WANNAN motors perform better than Simens. The electrical components are made from DELIXI (same brand that Chinese satellite launch center uses).

7. Gear driven through high precision gears.
The gears are treated by hardness quenching and processed by a milling machine. Thus maintain high concentricity with the shaft. These guarantee high performance and improved capacity over belt driven models.

8. Lubrication System, adding grease to main shaft guarantees lubrication without having to turn the machine off.

9. Key parts
The key working parts become stronger after modifying the material, heating processing technology etc. These main parts are forging pieces. Now, the processing of our ring die can reach 800-1000MT. The ring die is assembled by quick-discharge clip.

Other features:
1. Use imported bearings (NSK) & seals to get better transmission performance, stable operation, and reduced noise.
2. Installed an advanced compensation serpentine-spring coupling to increase safety. Also has a new structure and lower failure rate during operation.
3. We have a patent on the ring die and four utility model patents on the pellet mills. The holes are very smooth under our patent processing technology.
4. High efficiency, lower power consumption, stable operation and production.

* Adopting aerodynamics technology & the current round principle, reduces the temperature in pelletizing chamber to around 90°C. As a result the machine can work well continuously.
* Controls temperature & exhausts extra steam through air circulation. As a result, performs well in non pressing areas to extend the life of ring die & bearings. The machine can run continuously.
