Grinding Ball Wear & Breakage by Impact & Abrasion Tests

18/10/2017· Flaking and pitting modes do not develop normally during grinding of ore in a ball mill because abrasive wear proceeds at a faster rate. Steel balls abrasion. The abrasive wear of the steel balls determined from the pin-on drum wear test ranged from 0.577 to 1.094 mm³/m. However, the most abrasion resistant type of balls, B1, had too short an impact life to be useful; and the least abrasion- …

Ball Mills - an overview | ScienceDirect Topics

3.6.1.1 Ball Milling. A ball mill is a type of grinder used to grind and blend bulk material into QDs /nanosize using different sized balls. The working principle is simple; impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell.

01/06/2018· The ball mill, liners and grinding media employed were made from stainless steel. This material of construction is superior over all else because of its durability and resistance to wear and tear. It is due to these reasons that contamination of the material was ruled out. Experimental validation on the absence of contamination through microanalysis (EDX) or chemical (ICP) techniques would ...
