Advantages and disadvantages of various processes of granulating powder

Advantages and disadvantages of various processes of granulating powder:

1. The advantages of the mixing and mixing granulation method are: the structure of the molding equipment is simple, the output of a single machine is large, and the particles are easy to dissolve; the disadvantage is that the uniformity of the particles is not good, and the formed particles have low strength.

2. The advantages of the pressurized granulation method are that the formed pellets have high bulk density, little added plasticizer content, and simple equipment and technology.

3. The advantage of fluidized granulation is high production efficiency, but the disadvantage is that the prepared particles are relatively loose, with poor sphericity and surface finish.

4. The advantage of spray and dispersion mist method is that the granulation process and drying process of the powder are carried out at the same time. The disadvantage is that the particle strength is low, the particle size is small, the particle shape is not easy to control, and defects such as hollows and surface pits are easy to appear.
