(2) strong basicity: NaOH mass concentration is about 25%, pH14~15；
(3) impact of abrading-ball: abrading-ball is rotated with ball mill, liner plate is detached from when abrading-ball is raised to certain height, with one
Fixed speed makees parabolic motion, then falls on liner plate, therefore, percussion of the liner plate by normal direction.
(4) abrasion of aluminum ore: there are aluminum ore particle (Mohs' hardness 7) between abrading-ball and liner plate, impact in abrading-ball
In liner plate and thereafter motion process tangentially, aluminum ore is worn (three-body-abrasion) to backing surface.
Under the above harsh operating condition, liner plate had not only born the corrosion of hot highly basic medium, but also bore the three-body mill with impact
Damage, meanwhile, it mutually promotes between corrosion and impact wear, so that the service life of liner plate is only had some months, cause to be produced into this way
This rising, and influence normal production operating.
The operating condition of corrosive wear is ever-changing, and the corrosive wear mechanism of material is different under different working conditions, researcher
