(a) High degradation
(b) High dissolution
(c) High flow of material
(d) High surface area
Which are the modes observed in ball mill?​

Answer 1

The size reduction of material has a disadvantage of high degradation.

• Size reduction is the process of reducing large substances into smaller particles. Size reduction is also known as Comminution and Diminution.
• The size reduction operation is done to increase the surface area of the particles, to allow mixing of particles, and to allow particles' rapid penetration.
• But the size reduction operation also has some disadvantages. Many substances are degraded during the process.
• Hence, the correct answer is option A) High degradation.
