The ball mill is a rotating cylindrical vessel with grinding media inside, which is responsible for breaking the ore particles. Grinding media play an important role in the comminution of mineral ores in these mills. This work reviews the application of balls in mineral processing as a function of the materials used to manufacture them and the …
Basic Mill Linings. Use rubber linings wherever possible due to lifetime, low weight, easy to install and noise dampening.; When application is getting tougher use steel-capped rubber, still easier to handle than steel.; When these both options are overruled (by temperature, feed size or chemicals) use steel.; Ore-bed is a lining with rubber covered permanent …
