- Powder dryers: Remove moisture from powders using heat or vacuum.
- Powder classifiers: Separate particles of different sizes or shapes.
- Powder compactors: Press powders into a solid form.
2. Describe the process of powder blending and its importance
Importance of Powder Blending
- Ensures uniform distribution of ingredients.
- Improves product quality and consistency.
- Prevents segregation and agglomeration of powders.
Process of Powder Blending
- Choose the appropriate blending equipment and settings.
- Load the powders into the blender.
- Operate the blender for a specific time or until the desired blend is achieved.
3. What are the common problems encountered in powder handling and how do you address them?
Common problems in powder handling include:

- Equipment corrosion: Use corrosion-resistant materials, coat equipment surfaces, or control environmental conditions.
- Cross-contamination: Clean equipment thoroughly, separate different powders, or use dedicated lines for each material.
4. Explain the principles of powder compaction and its applications
Powder compaction involves applying pressure to powders to form solid shapes. Principles include:
- Particle rearrangement: Powder particles are rearranged under pressure to achieve higher density.
- Plastic deformation: Particles undergo plastic deformation, resulting in increased bonding.
- Interparticle bonding: Particles form bonds due to intermolecular forces or chemical reactions.
Applications of powder compaction:
- Pharmaceutical tablets
- Ceramic parts
- Metal components
5. Describe the role of particle size and shape in powder handling
Particle size and shape significantly affect powder behavior:
- Size: Smaller particles have a larger surface area, affecting flowability, caking, and reactivity.
- Shape: Irregularly shaped particles can interlock, leading to poor flowability and compaction.
Controlling these factors is crucial for optimizing powder processing and handling.
6. Explain the safety precautions and regulations for working with powders
Safety precautions for handling powders include:
- Wearing appropriate personal protective equipment (PPE), including respirators, gloves, and eye protection.
