corrosive wear in wet ore grinding systems

Corrosive Wear in Wet Ore Grinding Systems -

1985-6-1  Wear processes in ball and rod mills have recently received increased attention in order to increase efficiency and conserve grinding media. Direct removal of metal from the grinding media surface by abrasive wear occurs in both dry and wet grinding. Additional corrosive wear is apparent during wet grinding, in which less resistant corrosion product films are abraded away.

CONTROL OF CORROSIVE WEAR IN GRINDING BALLS

1991-1-1  255 CONTROL OF CORROSIVE WEAR IN GRINDING BALLS DURING WET GRINDING OF HEMATITE ORE A.W. Lui, V.S. Sastri and J. McGoey Metals Technology Laboratories, CANMET, 568 Booth Street Ottawa, ON, Canada K1A0G1 ABSTRACT Reduction of wear loss of steel balls during wet grinding of hematite ore was achieved by the use of corrosion inhibitors.

Influence of pyrrhotite on the corrosive wear of

1984-6-1  In the absence of sulfide-bearing minerals such as pyrrhotite, corrosive wear of the grinding balls in the wet grinding of magnetite ore was relatively small, even in the pres- ence of oxygen. The presence of pyrrhotite significantly increased the corrosive wear of mild steel and HCLA steel balls, especially in the presence of oxygen.

Practical aspects of corrosion in the wear of grinding ...

1987-5-1  An extensive program of marked ball wear testing (MBWT), laboratory corrosion studies, and worn ball surface analyses has been used to gain insight about the role of corrosion in the overall wear process. In some environments, localized corrosion is observed; the actual wear mechanisms in such cases are pitting/spailing and abrasion. Factors affecting the occurrence of pitting include the ...

Wear of grinding media in the mineral processing

1989-11-1  Within the mineral processing industry, a range of grinding conditions exists which include semiautogenous grinding (SAG), rod milling, and conventional ball milling. Each of these mill environments presents a unique environment for grinding media, requiring the application of specific physical and chemical properties for optimum grinding media performance.

Assessment of wear mechanisms in grinding media

1985-8-1  The effect of grinding media composition, mineral type, and slurry environment on the wear rate of various grinding media (balls) are discussed. Sufficient wear data have been obtained and correlated. Modes of wear were determined from examination of the ball surfaces using scanning electron microscopy. Five modes of wear have been identified to be operative under certain slurry conditions

What is the Effect of Chromium on Wet Grinding

2018-9-18  Because of higher efficiency, wet grinding is more widely used than dry grinding, but leads to an increased consumption of grinding media due to corrosion in some ores. In dry grinding, the wear rate of high chromium cast irons is frequently ten

Effects of percent solids and mill loading on ball wear

1985-8-1  The effects of percent solids, mill loading, and grinding time on product size distribution and ball wear were studied in a laboratory ball mill for a taconite ore. Mild steel balls and HCLA steel balls were used to examine the role that ball hardness play in grinding. Net production of −44-µm (−325-mesh) material reached maximum at 70% solids, whereas the ball wear decreased as pulp ...

Determining Corrosion Rates in Industrial Ore

2017-11-21  Pea Ridge Iron Ore Co. charges carbon steel grinding rods that are 3 in In diam and 13 ft in length. The total grinding rod wear rate is 0.9 lb/st of dry ore. This is equal to a linear penetration rate of 230 mpy; therefore, corrosion is directly responsible for about 4 pct of the total grinding media wear in the rod mills at Pea Ridge Iron Ore Co.

A discussion on the measurement of grinding media

Wet grinding can also add a corrosive component to total wear mechanism, and then wear rates are expected to rise from synergies between corrosive and abrasive components. Though corrosion phenomena are broadly accepted to happen in wet grinding - even when the ball alloy has high chromium content - studies on verifying its importance are scarce.

How to Reduce Steel Consumption in Grinding Mills

2017-8-26  An indirect method of measuring corrosion contribution is to compare steel wear in wet and dry grinding. Metal loss per ton of ore ground is higher in wet grinding than in dry grinding for a typical ore of average work index 13 kWh/t. It is difficult to explain the large increase in the rate of metal loss in wet grinding unless some mechanism ...
