"We had to design the system accordingly by using 20,1/2-foot-long lining plates
for the required horizontal clearance and strong triple rail with large bracing for the 15-foot cantilever required under the bottom brace of the system.
Magnetic ball mill lining plates have been granted two state-issued patents and are now in use in more than 100 balls mills in China, at operations such as the iron ore mines of Waitoushan, in Liaoning Province, Shirengou, Hebei Province and Wuyang, Henan Province, as well as the Wulong gold mine in Liaoning.
The operating principle of these lining plates is that particles of ore and the balls of the grinding media are attracted onto the liner plates and gradually form a protective layer.
* Lighter weight - Due to the thinner lining plates and the fact that fastening bolts are not used, the weight of the magnetic plate lining is 40-50% of that of the manganese steel liner, reducing the necessary power for the ball mill by 6-10%
