8.0 POWDER PROCESSING
3. Crushing or grinding the raw materials into very fine particles.
4. Mixing them with additives to impart certain desirable characteristics.
5. Shaping, drying, and firing the material.
6. Figure 8.3 shows the processing steps involved in making ceramic parts.
Figure 8.3 Processing steps in making ceramic parts.
8.3.3 CRUSHING AND MILLING
1. Crushing and milling are the processes used to reduce the ceramic particle size
from coarse to fine particle distribution.
2. It is important because as fine particle distribution obtained, the properties of
ceramic compaction is improve in term of the density, hardness and fracture
toughness etc.
3. Common equipments to perform crushing and milling activities include jaw
crusher, rotary crusher, hammermill, crushing roller etc.(Figure 8.4).
