Identify the non-screening device\nWhich of the following is NOT considered industrial screening equipment for size classification?

Introduction / Context:
Screening separates particles primarily by geometric size using apertured surfaces. Many devices fall under this umbrella (static grizzlies, vibrating screens, trommels), but other separation devices operate on different principles and thus are not “screens.” Distinguishing them avoids specification errors.

Given Data / Assumptions:

• Industrial minerals or aggregates application context.
• Terminology uses standard equipment names.

Concept / Approach:
A Sharpies centrifuge is a type of solid–liquid centrifuge used for fine particle separation from liquids via centrifugal force. It does not employ a perforated screening surface to classify dry or wet solids by size. In contrast, vibrating screens and banana screens are dynamic screens with apertures; grizzlies are stationary bar screens for coarse scalping; trommels are rotating cylindrical screens. Therefore, the centrifuge is the outlier and not an industrial screening device.

Step-by-Step Solution:

Verification / Alternative check:
Process flow diagrams separate screening/sizing blocks from solid–liquid centrifugation blocks; vendors classify them into different product families.

Why Other Options Are Wrong:

• The other listed devices are all aperture-based classifiers and thus are screening equipment.

Common Pitfalls:
Assuming any rotating cylindrical device is a trommel; only those with apertures for size-based separation qualify as screens.

Final Answer:
Sharpies centrifuge
