SAG Mill

The SAG Mill is a machine added by Ender IO.It uses Micro Infinity (µI) to grind (or mill) items into their crushed variants, like Ores into Dusts.The SAG Mill has four output slots; recipes can have 1-4 different outputs, with different chances of obtaining those outputs. Uniquely, the SAG Mill can use Grinding Balls made from various materials to increase energy efficiency (resulting in

What's the Difference Between SAG Mill and Ball Mill

Nov 26, 2019· 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.

SAG mills walk a tightrope of loading efficiency. On the one side, overloaded mills mean inefficient ore reduction, naturally leading to increased energy consumption. On the other side, an underloaded SAG mill leads to an increase in critical impacts, causing damage to critical media and mill liners, and resulting in costly repairs and downtime.

AG/SAG mills are often used as the first stage in a two- or multiple-stage grinding process, where the second stage is carried out by the ball mill, but they can also be used as a one-stage grinder. The absence of, or reduction in the number of, balls means they can be less costly to operate than ball mills. SAG mills of over 40-foot diameter
