1. The mixing homogeneity CV≤5% within 50~90 seconds;

2. Large loading changeable range: The coefficient of the loading changeable range is 0.3~0.8;

3. No segregation: Within one minute after mixing uniformity, no grading phenomenon happens and no segregation caused by the difference of weight, size, etc;

4. Fast discharging and little residue: The bottom is four-leaf opening structure;

5. Large number of liquid additives: Even if 30% liquid is added, materials can still be mixed uniformly.
