A discussion on the measurement of grinding media

2016-7-1  In fact, wet grinding gathers all the necessary elements for the occurrence of an active corrosion process: large surface area of the grinding media, an even larger surface area of ore being ground, an open circuit corrosion potential in the mineral particle, more noble (cathode) than the grinding media (anode), and continuous abrasion which removes any protective film that may have formed on the surface of the grinding media . Additionally, the abrasive wear

Consumption of steel grinding media in mills A

2013-8-1  Mill feed rate is thought to influence consumption of grinding media in that it influences the wear mechanisms acting on the media. At low feed rates, impact forces are considered to dominate over abrasion ( Gates et al., 2007 ) and Howat and Vermeulen (1988) have observed that at low feed rates, when the residence time of particles within the

Exploring ball size distribution in coal grinding mills

2014-5-1  It has been shown that mill capacity is linearly correlated to media surface area, thus using 30 mm balls as top size which leads to a fine ball size distribution in the mill is evidently a better approach than the current approach of using larger ball sizes. However the fact that the coal feed to this plant is known to be contaminated with a small fraction of hard-to-grind stone, which will strongly impact on

Marked Ball Wear Test 911 Metallurgist

2018-4-10  Marked Ball Wear Tests. The effect of mill atmosphere on the ball wear of mild steel during grinding of coal with and without additions of pyrrhotite is shown in Figure 1. The ball wear after 60 minutes of grinding increased from 4.7 to 8.5 to 23.0 mg/ball when the mill atmosphere was changed from nitrogen to air to oxygen, respectively.

Grinding Media Wear Rate Calculation in Ball Mill

2017-4-29  Then in ball-wear formula (25), T = 6.9/K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = 6.9Wt/Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/6.9Wt are all
