The Effect of Powder Specific Gravity on Mixing

The Effect of Powder Specific Gravity on Mixing
The specific gravity of powder is an important factor affecting the mixing process, which can be affected in the following ways.
1. The impact of specific gravity differences between powders on powder mixing:
1) The smaller the difference in specific gravity between powders under the same conditions, the easier it is to achieve uniform mixing. This is because uneven phenomena such as weight segregation are less likely to occur during powder movement;
2) The greater the difference in specific gravity between powders under the same conditions, the more difficult it is to achieve uniform mixing. This is because the heavier powder particles tend to sink during movement, while the lighter powder particles tend to float upwards, making it difficult for uniform mixing.
2. The influence of powder specific gravity on flowability can indirectly affect the difficulty of powder mixing:
1) The larger the specific gravity of the powder, the better its fluidity during mixing. This is because the increase in weight has an impact on powder movement.
2) Generally speaking, the better the fluidity, the easier it is for the powder to homogenize and mix.
Note: If the flowability of the powder is too good, it will actually bring difficulties to homogenization and mixing, and this issue will be discussed in terms of flowability.
