Primary Grinding Ball Mills. The environment in primary ball milling can best be described by giving equal considerations to both impact and abrasive conditions. The relatively large ball sizes employed [3 4 (75 100 mm)] contribute a significant impact component to the overall wear.
Ball Mill Ball Mills Steel Ball Mill. Our combined experience in ball mill design and process equipment development totals more than 60 years and allows us to put a unique spin on steel and lined mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800s.
With regards to 3.5" 4" media, typically for Ball mills of this size (16'), max size of ball used should be around the 50 60mm. I feel that a 4 ball in a 16 Ball Mill is too large and more suited to SAG Milling. You risk damaging liners (rubber, composite or full steel) as well as trommels and feed chutes in

Laboratory results of marked ball wear tests are used to discuss the relative significance of corrosive and abrasive wear in wet grinding. The electrochemical mechanism was investigated by correlating the corrosive wear with the corrosion current obtained from polarization curves under abrasion.
