Effect of Rod Mill Feed Sizing on Grinding Performance

Rod Mill Fines Content. The presence of "fines" in open circuit rod mill feed has long been recognized as an important factor for both stable and efficient mill operation. Although addition of extra fines to rod mill feed was common practice in the past, few details have been reported. The fortunate exception is the experience at Frood Stobie.

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 ...

Solved 1. A wet overflow mill of dimensions 3.05 mx3.05 m

2. A wet rod mill was loaded to 45% of its volume with a charge consisting of a gold ore and steel rods. The rod diameter was 70 mm. the mill has inner diameter of 1980 mm and was rotated at 21 rpm with a rod load of 23.8 t. The rock volume was 0.4 times the rod volume after taking into the account the porosity of bed.

Titanium Ore Processing and Beneficiation

¾" crushed ore passes through a peripheral discharge Rod Mill at high dilution (35 to 40% solids). This minimizes over-grinding and sliming of the feed particles of titanium. The peripheral discharge product from the rod mill is elevated to a Duplex Mineral Jig making a rougher heavy mineral concentrate for retreatment in a Simplex Mineral Jig.

Autogenous Mill | SpringerLink

The autogenous mill will grind the material to the extent that the content of the particles with particle size <0.074 mm accounts for 20–50% of total quantity of product, and crushing ratio is 4000–5000, which is over 10 times that of ball mill and rod mill. The maximum particle size of the lump ore fed into autogenous mill is 300–350 mm.
