RoM Ball mills, like SAG mills, utilise coarse rocks in the RoM feed as grinding media but with 25 – 40% steel balls added instead of 5 – 18 % volumetric filling in SAGs which may become advantageous when the coarse fraction in the RoM feed is depleted. RoM ball mills have been introduced to avoid the problems encountered with operations ...
Wet disc mills generally have simpler mechanical structures and fewer moving parts than traditional ball mills, which can mean lower downtime and operating costs. 3. Abrasiveness. Harder materials may wear out the ball mill more quickly than a sturdier designed wet disc mill, requiring more frequent grinding media changes.
