Achieving cost reduction and improved durability! Repairs and maintenance using appropriate methods!
We will introduce examples of repairs and maintenance for the "Vertical Mill for Coal Pulverization." When repairing the shaft of the "Eccentric Shaft," we recommend plating repairs over build-up repairs due to their superior durability. This method has less thermal impact and reduces the effect on the main body. Additionally, for the "Reduction Cylinder," we provide comprehensive support based on inspection results, including plating repairs, reverse engineering, and procurement of consumable parts. 【Case Overview】 <Eccentric Shaft> ■ We recommend plating repairs over build-up repairs for the shaft due to superior durability. ■ There is less thermal impact, which can reduce effects on the main body. <Reduction Cylinder> ■ We collect used reduction cylinders for disassembly and inspection. ■ After repairs, we conduct trial runs and operational tests before returning them. ■ Maintenance is possible even without drawings, and we can accommodate any manufacturer. *For more details, please refer to the PDF document or feel free to contact us.
