UNIQUE POLYMER SYSTEMS provides specialised solutions for the protection and repair of industrial equipment exposed to extreme wear. This case study details the successful repair of a coal grinder using our UPS 519 HD HEAVY DUTY CERAMIC to rebuild and protect worn steel sections.

In an industrial setting, the steel sections within a coal grinder were experiencing severe wear due to the abrasive nature of the coal. Over time, this constant flow of material had eroded the recessed sections of the steel work, threatening the grinder's performance and requiring immediate repair to prevent further degradation.

The primary challenge was to restore the worn sections of the coal grinder to their original condition, ensuring that the repairs would withstand the harsh operating environment and prevent future wear. The solution needed to effectively fill and smooth out the damaged areas, eliminating any exposed leading edges that could exacerbate wear.

UNIQUE POLYMER SYSTEMS provided a targeted repair solution using UPS 519 HD. The repair process involved the following steps:

Surface Preparation

- The substrate was abrasive grit blasted to remove any existing coating and prepare the surface to ISO 5801/4 SA 2.5 (SSPC-SP 10/NACE 2) standards. This preparation was crucial for ensuring optimal adhesion of the repair material.

Application of UPS 519 HD HEAVY DUTY CERAMIC

- UPS 519 HD was applied to the damaged areas of the grinder using an applicator. The material was used to fill and smooth out the recesses, effectively rebuilding the worn sections and removing any exposed leading edges. This approach ensured that the repaired areas were fully protected against further wear and abrasion.

The application of UPS 519 HD successfully restored the coal grinder to its original condition. The repaired sections were effectively protected from future wear, ensuring that the grinder could continue to operate efficiently under demanding conditions.

This case study demonstrates the effectiveness of UNIQUE POLYMER SYSTEMS' heavy-duty ceramic coatings in restoring and protecting industrial equipment subjected to extreme abrasion. Our advanced materials and precise application techniques provided a durable solution that extended the service life of the coal grinder and maintained its operational efficiency.
