Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : In attrition mill, overfeeding lowers the grinder performance.
Reason (R) : The fineness of grinding in attrition mill is controlled by the type of plates and the gap between them.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
• C. (A) is true but (R) is false.
• D. (A) is false but (R) is true.

Hint:

Remember that overfeeding affects the feed rate and throughput balance of a mill, whereas plate configuration and gap settings control the particle size of the processed material.
