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 ...

Ripple Mills are used to crack the Palm nuts. The nuts enter from top of the mill and are impacted several times between the stationary plates and turning rotor. The impact from the rotor cracks the nuts. The output from the Ripple Mill is a mixture of kernels and Shells. After cracking, next step is the separation of Palm Kernels and Shells.

1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powder-like structures. 3.
