Question:
The peripheral surface speed of faster roll in rubber-roll sheller is
The peripheral surface speed of faster roll in rubber-roll sheller is
Show Hint
Rubber-roll shellers dehusk paddy by differential speed action of two rubber rolls.
Updated On: May 7, 2026
- \(8\) to \(10\,m/s\)
- \(10\) to \(13\,m/s\)
- \(13\) to \(16\,m/s\)
- \(16\) to \(20\,m/s\)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
A rubber-roll sheller is used for dehusking paddy. It contains two rubber rolls rotating at different speeds.
Step 1: Paddy grains pass between two rubber rolls.
Step 2: One roll rotates faster than the other.
Step 3: The difference in speed creates shearing and compressive action.
Step 4: This action removes the husk from the paddy grain.
Step 5: The peripheral surface speed of the faster roll is generally: \[ 10\text{ to }13\,m/s \] \[ \boxed{10\text{ to }13\,m/s} \]
