- Spray dryer
- Blunger
- Ball mill
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Granules are commonly required in ceramic processing for pressing operations.
A spray dryer is used to convert ceramic slurry or slip into dry granules.
In spray drying, the slurry is sprayed into a hot air chamber as fine droplets.
The water evaporates quickly from the droplets.
As a result, powder granules are formed.
These granules have better flowability and are suitable for pressing.
A filter press is used to remove water from slurry and make filter cake.
A blunger is used for mixing and making slip.
A ball mill is used for grinding and mixing raw materials.
Therefore, the equipment used to prepare granules is:
\[
\text{Spray dryer}.
\]
