Ceramic Ball Mill

Ceramic Brick Lined Ball mill

Ceramic ball mill linings will eventually wear down and need replacement. Even old pebble mills with Burrstone linings can be relined with high-alumina brick. We tear out and dispose of the old brick, check the steel shell thickness, repair or replace and thin or corroded section and the install the new brick lining.

We use only high quality, fine-grain 90% (or 96%) alumina brick with tongue and groove design. Bricks are secured and grouted with pure Portland cement or two-part epoxy. When it is time to reline a mill that is also a good time to check the bearings and drives components. If the mill is old and has babbitted bearings we can machine the trunions and replace the old friction bearings with sealed roller bearings. We can also rebuild or replaced drive components including ring & pinion gears and reducers and motors.
