- Disk separator
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Grain cleaning and grading machines utilize physical property differences such as size, length, density, surface texture, and shape.
Step 2: Detailed Explanation:
A spiral separator separates seeds and grains based on roundness and rolling friction.
Round seeds roll down helical inclined flights at high speed, generating centrifugal force that casts them into the outer flight, whereas flat, wrinkled, or irregular seeds slide slowly along the inner core.
Step 3: Final Answer:
Therefore, a spiral separator separates grains according to their roundness.
