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.
Usually, the ball-filling rate is about 40%. The mill balls' size is initially 30–80 cm in diameter but gradually wears away as the ore is ground. In general, the ball mill grinder can be fed either wet or dry. The ball mill machine is classed by electric power rather than diameter and capacity.
The BM2200+ Planetary Nano Ball Mill operates with two grinding bowls in the sizes 20 ml, 45 ml or 80 ml, which turn with a transmission ratio of 1 : –2 relative to the Sun Wheel. The grinding Jar is arranged on the sun wheel of the Planetary Nano Ball Mill off centred.
