Metso Cone Crusher Torch Ring 7012080200
When it comes to maintaining the performance and longevity of your Metso cone crusher, choosing the right Torch Ring 7012080200 is essential. This critical wear component plays a vital role in securing the mantle assembly and protecting expensive internal parts during liner changes. In this article, we will explore the function and applications of the Torch Ring, its material options, and how SAIKUANG can provide you with a high-quality replacement.
About Metso
Metso is a global leader in the supply of technology and services for the mining, construction, recycling, and process industries. Headquartered in Helsinki, Finland, the company was incorporated in 1999 through the merger of Valmet Corporation and Rauma Corporation. Metso’s mining and construction business serves customers worldwide, offering a comprehensive range of crushers, screens, and wear parts. The company’s HP Series cone crushers are among the most widely used in the aggregate and mining industries, known for their high productivity and reliability.
Function and Application of the Torch Ring 7012080200
The Torch Ring, also known as a burning ring or cutting ring, is a critical sacrificial component used in the mantle locking assembly of the cone crusher. Its primary functions are twofold:
Mantle Locking and Pre-tensioning: The Torch Ring acts as a compression washer between the head nut and the mantle. It fills the gap between these components, ensuring the head nut can properly tighten and pre-tension the mantle against the head. This prevents the mantle from loosening during operation, which could cause catastrophic mantle spinning and uneven wear.
Protection of Critical Components: The Torch Ring shields the head nut and main shaft threads from direct impact and abrasive wear. More importantly, it provides a designated zone that can be flame-cut to release the tension on the liner during change-outs, protecting the expensive head nut and main shaft from torch damage.
The Torch Ring 7012080200 is specifically designed for the Metso HP100 and HP300 cone crushers. It is a drop-in replacement component with a weight of approximately 2.1 kg. This part is essential for maintaining proper mantle clamping force, which is critical for achieving maximum crushing capacity and reducing wear on other wear parts.
Material Selection and Advantages
The Torch Ring 7012080200 is manufactured from high manganese steel in grades such as Mn13Cr2, Mn18Cr2, and Mn22Cr2. These materials are chosen for their excellent work-hardening behavior. Under impact and abrasion, the surface of manganese steel hardens significantly, increasing its resistance to wear.
| Material Grade | Key Characteristics |
|---|---|
| Mn13Cr2 | Standard high manganese grade with good impact resistance and work-hardening capacity. Suitable for general cone crusher applications. |
| Mn18Cr2 | Premium grade with improved wear resistance and longer service life in abrasive conditions. |
| Mn22Cr2 | Ultra-premium high manganese grade for severe abrasion and high-impact applications. Offers the highest wear life among the three grades. |
All grades are produced under strict quality control and can meet ASTM A128 requirements where applicable. As the Torch Ring experiences impact from crushing forces, its surface hardness increases from the initial range to over 400–500 HB, providing excellent wear protection.
