1. Machine body and base are connected flexibly without rigid contact.
2. Machine base is of high intensive, ductile cast iron which is efficient in avoiding crack caused by vibration.
   Ductile cast iron has anti-vibration function of cast iron, intensity of cast steel and good performance in impact resistance.
3. Reducer made in China has similar performance as Flender of Germany
   Reducers are of high manufacturing technology from professional reducer manufactures, which will contribute a lot to stability of the whole machine
4. Elastic sleeve pin sets couplings are adopted between machine body and reducer
   Comparing with Nylon pin which is easy to break off, elastic sleeve pin sets will increase equipment stability greatly.
5. High-density blads are adopted on classifier.
6. Frequency conversion control is adopted in the classifier.
   Frequency conversion control will cost less engergy comparing with electromagnetic speed control and there will be better control acuracy, better flexibility and higher automation level.
7. Bypass powder collector is adopted.
8. Equipments are distributed under same resistance program.
9. Two outlets of powder collector and that of dust collector are distributed within one line.
10. Set maintenance platform
    Setting maintenance plantform will make maintenance of mills more convenient and safer.
