Installing lining bricks in the ball mill is an essential operation step to protect the mill shell, optimize grinding efficiency, and ensure the prolonged service life. So the workers should be serious about this task. Before installing the lining bricks on the ball mill, here are several preparatory tasks need to be completed:

1. Cleaning and Strict Inspection:

Firstly, the mill must be thoroughly checked and cleaned for any risk that could affect the installation process. All residual material should be removed from the internal surfaces of the mill shell (ore, slurry, spent grinding media, dust, and debris)and any existing bolt holes or anchor points. Neglecting shell imperfections risks poor brick adhesion, uneven stress distribution, and premature lining failure. Furthermore, the lining bricks must also be carefully inspected to ensure they are free from defects, cracks, or other imperfections.

2. Precision Adhesive Selection and Preparation:

Selecting the correct high-performance adhesive is paramount to the lining's service life. Normally, use epoxy resin or white cement to do the paste work. Before using the epoxy resin, should look through and understand the instructions for use thoroughly. When the mix is improper, whether it is incorrect proportions, insufficient mixing, or the introduction of impurities, which will lead to weak adhesion or complete failure. Meanwhile, some adhesives need to undergo a specific curing period under controlled conditions before application or loading into the mill. Once the adhesive is ready, the ball mill lining bricks should be arranged in the correct pattern and order, with close attention paid to any openings such as the feed inlet and discharge outlet, or any special arrangements.

3. Finished work:

Then, place the bricks in the pre-determined layout and sequence. And ensure the full contact between the bricks, the adhesive, and the ball mill shell. As the installation proceeds, any excess extruded epoxy resin or cement must be removed immediately, before the adhesive cures.

In addition, need to check whether there are small gaps, vpids, or areas.

If it exists, it needs to be filled and smoothed out with the specified adhesive or compatible filling compound.
