Methods to Estimate AG/SAG Mill Power Requirements
A linkedin.com group was recently discussing this by asking: I’ve tried to estimate AG/SAG Mill power requirements using several different methods: (1) Using the results of SMC data (2) Using SAG Power Index (SPI) data (3) Using the 1989 Barratt method updated on Alex Doll’s Web site (February 16, 2015) (3) Using Don Burgess’ method (11th […]
Understand Fluorine in Copper Concentrate (F in Cu Conc)
A copper flotation concentrate is over limit on Fluorine (F) content and Contamination. When assaying and plotting Copper (Cu) from times concentrates and the related fluorine and Magnesium Oxide (MgO) assays in various ways as shown below; one can see the obvious relationships. In the case, reducing Fluorine content and contamination of the copper conc […]

Table of Bond Abrasion Index for Varied Minerals-Materials
The Bond Abrasion Test determines the Abrasion Index, which is used to determine steel media and liner wear in crushers, rod mills, and ball mills. Bond developed the following correlations based on the wear rate in pounds of metal wear/kWh of energy used in the comminution process. Determining rock abrasivity in the laboratory ref
How Abrasion Index affects Wear Rates
What is the relationship between Abrasion Index affects Wear Rates of steel ball mill and rod mill liners as well as the wear life or consumption of grinding balls or rods. A little bit of data on crusher (gyratory and roll) liner wear life in also shown. Rubber wear data.

Estimated/Approximate Steel Liner Wear Life/Rate
A mill’ steel liner wear rate and total useful operating life is a function of its hardness (mostly). Here is a chart displaying Liner Hardness on the Brinell Scale as a function of the tonnage of ore/rock milled/processed. Not showed here is the impact a mill’s RPM has on the liner’s wear rate. Comminution and Energy Consumption: By […]
Estimated/Approximate Rubber Liner Wear Life/Rate Cost
In a Ball Mill (particularly) the wear rate or wear life of Rubber depends much on the Ball Size/Diameter used in that mill. The grinding media size which itself is much of a function of the ore/material P80 feed size into that mill. The other primary and addition factor contributing to a mill rubber liner […]
