What's the Difference Between SAG Mill and Ball Mill
The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

Grinding Mill Computer Model
Initial indications are that the mill motor size recommended is higher than that supplied by the manufacturer though this probably reflects the less accurate estimate of the mill data base with only a limited number of variables considered. 3.2 Rod Mill Design A different approach is taken with the rod mill design where equations by Bond and
Grinding
Optimize mill operation – with gearless mill drives. Siemens has provided almost 100 SIMINE Gearless mill drives to the mining industry since 1980. In these thirty-plus years, SIMINE Gearless mill drives have accumulated a combined total of over 500 years in operation time – and this number is steadily growing even as you read this.
STEPPING FORWARD: USING VARIABLE SPEED DRIVES …
The breakage rate function shape of the SAG mill is largely governed by the mill load particle size distribution and mill speed. The feed in the mill contains fractions of ore that serves as the grinding media. Larger ore fractions break the smaller particles but also breakdown themselves and exit the mill as a product.
