Which grinding mill uses horizontally arranged rods as the grinding media and is known to deliver a more uniform granular product with minimal fines generation?

Introduction / Context:
Different tumbling mills use different media: balls, rods, pebbles, or ore itself. Media geometry affects breakage mode and product size distribution.

Given Data / Assumptions:

• Goal is uniform product with fewer fines.
• Grinding elements are horizontally arranged rods.

Concept / Approach:
Rod mills grind by line contact rather than point contact of balls. This reduces overgrinding and limits fines production, making rod mills suitable for feed to ball mills or for specific sizing where slimes are undesirable.

Step-by-Step Solution:
Identify mill with rods: rod mill.Relate line-contact to minimized fines.Select rod mill accordingly.

Verification / Alternative check:
Flowsheets often place rod mills ahead of ball mills to control fines, validating the choice.

Why Other Options Are Wrong:
Compartment/Tube mills: ball media.Pebble: ceramic/natural pebbles; different duty.

Common Pitfalls:
Assuming all tumbling mills behave the same; media geometry matters.

Final Answer:
Rod mill
