ادامه مطلبSAG Mill Operational Problems The processing capability of a semi-autogenous (SAG) mill is greatly affected by ore geology and operating variables within the mill. The key issues are broadly classified in to three categories: field of breakage, flow through the grate and pulp lifters and charge motion.
ادامه مطلبGearless mill drive (GMD) technology has further expanded the use of large SAG milling allowing Outotec to produce the world's largest SAG mill of 42' in diameter drawing power at 28 MW. Today, Outotec is the world leading supplier of gearless SAG mills operating globally.
ادامه مطلبBased on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.
ادامه مطلبIf a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders.

ادامه مطلبThe 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 ...
ادامه مطلبeach lane has a constant cross-slope, but those of the outer lanes are greater than those of the inner lanes. For high-type roadways (such as freeways), cross-slopes are nor-mally 1.5 to 2.0 percent. Shoulders or parking lanes slope away from the centerline at 2 to 6 percent. As a general rule, superelevated sections will be constructed in a single
ادامه مطلبSingle stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.
