Recommended Rod Mill Bar Length
Ever asked what size/length rods (bars) you need for charging your rod mill? It depends on the rod mill diameter itself. To prevent most conditions leading to rod charge tangling, the generally recommended relationship of rod length to mill diameter Inside liners is 1.4 to 1.6. When this ratio becomes less than 1.25 the risk of […]
Recommended Mill Operating Speed RPM
Here is a table of typically recommended ball mill speed or rod mill speed as a % of critical will operate at. In summary, the larger the mill, the slower you will want the RPM to be set at and the mill to turn. Ref
Radial SAG Grate & Pulp Lifter Design
SABC Grinding Circuit Operation & Optimization
When operating a grinding circuit (at Granny Smith) under a wide range of conditions: campaigning very competent underground ore followed by soft oxide, primary versus secondary crushed feed and finally single-stage SAG and conventional SAG, ball mill and pebble crusher (SABC) configurations. Economics changed and a review of the circuit performance including modelling and simulation resulted in the […]
How a Grate Discharge Ball Mill Works
Here I try to explain how ground slurry is discharged from a grate ball mill (or SAG). How it works is, the slurry flows across the grate as it would a screen panel. On the other side of the grate/screens are veins like a pump impeller. As the mill turns/rotates the slurry is “pumped” out […]
Work Index and Sample Size
In mineral processing, is the Bond work index of an ore different if the determination is made at a finer grind size? Is rock hardness is independent of testing size? The answer to this question is that generally no, the size that the index is measured at does not effect the Bond work index value. Bond work […]

Hydrocyclone Feed Pump and Pressure
For a hydrocyclone to work at peak efficiency the volume of slurry and the feed pump delivery pressure must remain constant. If the cyclone feed pump is allowed to SURGE, the up and down pressure will cause poor separation at the point of high and low operating pressure. There is a cycle to a surging pump […]

Troubleshooting Hydrocyclones
Here is a simple Table for Troubleshooting Hydrocyclones. Other Hydrocyclone Troubleshooting Tips: Underflow is too wet Apex is too large Vacuum control valve is open too far Inlet pressure is too low Pump is cavitating Underflow is too dry (cone is plugging) Apex is too small. Vacuum control valve is closed too far. Percent solids is too […]
