The bond abrasion test determines the abrasion index which is used to determine steel media and liner wear in crushers rod mills and ball mills. bond developed the following correlations based on the wear rate in pounds of metal wear/kwh of energy used in the comminution.
The cost of replacement of the metal worn from the working surfaces of the balls and liners of a mill often represents a considerable fraction of the cost of operation of the plant and so is of some real economical importance. in spite of this importance, however, the amount of information in available on this subject is amazingly small and, unfortunately, is insufficient to form the basis of.
The experimental results showed that the abbott-firestone curve can evaluate the lifter surface topography. the wear rate of the lifter specimen is increased first and then decreased with mill speed and grinding media size. increasing ball filling will increase the wear rate, and the grinding media shape of ball has a maximum wear.
The liner has a great important role in protecting the cylinder and effecting the movement of steel balls. as the grid ball mill's inside suffered the continuous impact of the steel ball and ore, so we have special requirement s for the ball mill liners mechanical characters. firstly, the liner must high wear resistance and impact.
