Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Screening equipment separates particulate mixtures into size fractions using perforated or woven mesh surfaces.
Step 2: Detailed Explanation:
Vibratory screens utilize high-frequency, low-amplitude vibration to fluidize the particle bed and pass fine particles through apertures without blinding or clogging.
While they offer exceptional sharpness and precision for separating very fine particles and flours, their throughput capacity per unit area is limited compared to heavy rotary or horizontal reels.
Step 3: Final Answer:
Hence, vibratory screens provide accurate separation of fine sizes with limited capacity.
