Before installing the lining bricks on a ball mill, several preparatory tasks need to be completed. 

1. Firstly, the mill must be thoroughly cleaned and checked for any damage that could affect the installation process. The lining bricks must also be carefully inspected to ensure they are free from defects, cracks or other imperfections.

2. Second, the correct adhesive must be selected and prepared according to the manufacturer's instructions. This may involve mixing and curing the adhesive before application.Once the adhesive is ready, the ball mill lining bricks should be laid out in the correct pattern and shape, paying close attention to any cutouts or special arrangements required for inlet/outlet pipes, inspection ports or other features.

3. Finally, the bricks are securely affixed to the mill shell using the adhesive, and any gaps or areas of uneven coverage are carefully filled or smoothed over. It is important to ensure that the bricks are installed with a consistent level of compression and are properly aligned, as this will affect the performance and lifespan of the mill.

Overall, careful planning and attention to detail are essential when preparing for the installation of lining bricks on a ball mill. By following these steps, the mill operator can ensure a smooth and successful installation that will provide long-term benefits for their operation.
