In the grinding of cement, slag, coal, and other materials, vertical mills serve as core equipment whose operational stability directly impacts the economic efficiency of the entire production line. However, due to the large volume and high abrasiveness of processed materials, even wear parts made from conventional wear-resistant materials often exhibit severe wear or even become unusable within just a few months. This necessitates frequent shutdowns for replacement, resulting in significant production losses and maintenance costs.

Severe Challenges: Wear Mechanisms and Typical Failure Components in Vertical Mills

During operation, materials enter the mill through feed chutes and undergo high-pressure crushing by grinding rollers and discs. The pulverized material is discharged by airflow while subjecting surrounding components to intense erosion. Fine particles proceed to the classifier for grading, while coarse particles return to the grinding disc via the recirculation system for further processing. Throughout this process, internal components face two primary wear mechanisms:

l l Erosion wear from high-speed dust-laden airflow

l l High-stress abrasive wear and particle impact

Key wear-resistant components in vertical mills include: conical guard plates and conical liner plates.

Operating in an extremely harsh environment, the lifespan of critical components is severely limited without protection from high-performance wear-resistant materials.

Premature failure of these parts not only increases spare part consumption but also causes unplanned downtime, significantly hindering the continuous and stable operation of production lines.
