Ball Mill Abrasion Index

A Mill Abrasion Test for Wear Resistance of Armour Stone

— The abrasion mill test uses increments of milling time to generate a weight loss curve, the slope of which gives the abrasion resistance index. This new index, k s is compared with wet attrition and aggregate abrasion values for a suite of 11 rocks with wide ranging strengths. Los Angeles Abrasion Test results are briefly mentioned.

Consumption of steel grinding media in mills – A review

— One of the earliest models was that of Bond (1943), who proposed a specific consumption rate for balls Ω E (kg/kW h) in wet mills of (14) Ω E = 0.16 (A i-0.015) 1.3 and for dry balls (15) Ω E = 0.023 (A i) 0.5 where A i is an abrasion index that depends on the ball material, which could range from A i = 0.016 for dolomite to A i = 0.891 for ...

ball mill abrasion index

Bond estimated the amount of wear in terms of kilograms per kWh based on the abrasion index, A;, i.e., Wet Ball Mill = kg kWh = 0.16(A i-0.015) 0.33; Dry Ball Mill = kg / kWh = 0.023A i 0.5; Replacement Ball Size. Rowland and Kjos proposed the use of their equation for the determination of the initial and replacement media size.

Ball Mill

The "KSJ" Tumbler Index Ball Mill for iron oxide lump cores, sinters, and pellets consists of a cylindrical drum constructed of mild steel plate. The two circular sides of the drum have two stub axles attached through two circular flanges. The axles are held in two double-row self aligning ball bearings with the common axis of the axles located in a horizontal plane.

Testwork: Bond abrasion index

The Bond Abrasion Index is a measure of how readily a rock sample will wear away steel that comes into contact with it. It is conventionally used to estimate the liner and media wear rate in rod mills, ball mills and crushers. This is a batch test and returns a result in units of grams (the amount of metal that wears off the test coupon).
