_____________________ baffles are installed within ball mills ?
Show answer Hide answer
Answer: A. Horizontal
Explanation
Horizontal internal baffles or lifter bars are installed inside ball mills to lift grinding media. Lifting media ensures proper cascading and cataracting motion for maximum particle impact breakage. Shell liners with horizontal profiles prevent media slippage against the rotating mill wall. Ball mills require internal lifters to impart sufficient kinetic energy to the grinding balls. Rotational speed and mill geometry dictate the optimal height and spacing of internal baffles. Wear resistant alloy steels are used to manufacture durable internal mill lining components.
Mineral processing operations optimize ball mill performance by selecting appropriate liner profiles. Power consumption in tumbling mills depends heavily on the lifting action of internal baffles. Regular inspection of mill liners prevents structural damage to the outer rotating steel shell. Vertical baffles are not standard because tumbling mills rotate horizontally around their primary axis. Options stating no baffles are used ignore the essential role of lifter liners in ball mills. Restricting the count to only two baffles contradicts standard industrial ball mill lining design.
