Matters needing attention when Alumina Ceramic Grinding Balls is installed and stopped

The linings of each silo of the ball mill are basically made of metal. When loading the balls in the air mill, you should first load a certain amount of material (or bulk cement) for buffering, and then install the ceramic balls to avoid a height difference of more than 3m. Cause the ceramic ball to hit the steel liner, cause microcrack damage, and increase the damage rate of the ceramic ball during the production process. In addition, during the cement production process, if the grinding is stopped due to reasons such as production and overhaul, it is necessary to avoid long-term empty grinding operation without material to avoid damage to the Alumina Ceramic Grinding Ballss, shorten the filling cycle and extend the service life.
