  • Grinding Ball Wear & Breakage by Impact & Abrasion Tests

    18/10/2017· Two types of laboratory wear tests were run on the grinding balls, repeated impact tests and abrasion tests The repeated impact tests simulated the ballonball impacts that occur in rotating ball mills that are known to cause balls to spall and break The abrasion test was chosen to simulate the abrasive wear that results from contact between ore and balls in ball mills No corrosion tests28/08/2017· During the “marking” method in one test (or one mill) can check several types of grinding balls Grinding balls have the same diameter but produced by different material (the raw materials chemical composition) Each type of grinding media marked differently – by different amount of holes As a rule, three or more tons of marked grinding balls loaded into ball mill Please note, largest experience party by tonnage means more representative testThe industrial tests stages V Marking grinding balls method07/05/2019· The industrial tests are divided into three groups depending on the kind: – tests by using ”marked grinding balls”; – tests conduction by the ” replacing grinding balls method ”; – tests providing with a new grinding balls (the new grinding balls loaded into an empty test mill)TESTING OF GRINDING BODIES IN THE BALL MILL
