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.

This is because if the solid-to-liquid ratio is too low, the slurry of the ball mill will be too thin which limits the effective use of the energy supplied to operate the mill. Conversely, a higher solid-to-liquid ratio results in a highly viscous slurry that restricts the movement of the balls and reduces the grinding efficiency.

The ball mill Ball milling is a mechanical technique widely used to grind ... materials (e.g. cellulose, chemicals, bres, polymers, hydroxy- ... ball-to-cellulose mass ratio, milling time, ball size and alkaline pre-treatment) on the morphology of the prepared nano-cellulose derivatives was undertaken by the group of Wang.22,23

In, under different ball charge filling ratios, ball sizes, and residence time, a continuous ball mill is studied for optimizing cement raw material grinding process. In [ 5 ], an adaptive control framework is presented for raw material blending process, and corresponding optimal control structure is discussed too.

Quality ratio of grinding ball and material: Generally, the mass ratio of grinding ball and material is better than 5:1. The volume of grinding ball and material filling is not more than 80% of the volume of the ball grinding tank, generally 40-60% is the best.

Effect of Ball Size and Ball to Powder Ratio Variation on Crystallite Size and Formation of Nanocrystalline Materials in Planetary Ball Mill December 2011 DOI: 10.1063/1.3663098

The raw material ratio is only 25 mg, and the ball mill speed is only 100 r/min. In Buzaglo's [ 32 ] study, the content of graphite was only 36 mg. In summary, these two ball milling methods have low production efficiency and high cost, so they are not suitable for road materials.
