Question

A generalized relation for crushing is \[ \frac{d(P)}{m} = -K \frac{dD}{D^n} \] The solution for this equation leads to Rittinger's law for 'n' equal to ______.

• A. 1
• B. 2
• C. 3
• D. 4

Hint:

Rittinger's law is applied when the energy required for size reduction is proportional to the surface area created by the reduction.

Answer 1

The Correct Option is A

- The given equation represents the generalized form for the crushing process where the exponent 'n' in the equation corresponds to the Rittingers law. 
- For the Rittingers law, 'n' is equal to 1, which suggests that the energy required for crushing is directly proportional to the size reduction. 
Conclusion: 
The correct value of 'n' according to Rittingers law is 1. 
Therefore, the correct answer is (A).
