Sandvik CH660 Mantle and Bowl Liner Replacement and Material Selection

[MikePhua]

In the maintenance of mining and crushing equipment, selecting the right parts and materials is crucial for ensuring optimal performance. The Sandvik CH660 is a cone crusher commonly used in ore crushing, with key components such as the Mantle and Bowl Liner playing a vital role in its efficiency and durability. The material and wear resistance of these parts directly impact the machine’s performance. This article will discuss common material selections, model replacements, and the benefits of using MN22Cr2 material for the Sandvik CH660 Mantle and Bowl Liner.
Sandvik CH660 Mantle and Bowl Liner

1. Mantle
   The Mantle is one of the core components of the Sandvik CH660 cone crusher, responsible for crushing ore and materials. The Mantle experiences significant wear due to constant friction with the crushed materials, so its wear resistance and strength are crucial. The common Mantle model for Sandvik CH660 is 442-9760. The choice of material and hardness is often determined based on the specific crushing operation and workload. Higher hardness materials offer increased durability and efficiency.
   
2. Bowl Liner
   The Bowl Liner is another key component of the Sandvik CH660, designed to support and contain the crushed materials. Like the Mantle, the Bowl Liner also wears out over time due to constant friction, requiring regular replacement. A commonly used Bowl Liner model is 442-8817. The material selection for the Bowl Liner, just like the Mantle, directly impacts the machine's production efficiency and maintenance schedule.
   

Advantages of MN22Cr2 Material
When selecting materials for the Sandvik CH660 Mantle and Bowl Liner, MN22Cr2 is a popular choice due to its superior wear resistance and toughness. MN22Cr2 is a high-manganese steel material that is well-suited for heavy-duty crushing operations. The specific advantages of MN22Cr2 include:

1. Excellent Wear Resistance
   The high manganese content of MN22Cr2 provides exceptional wear resistance, allowing it to endure extended periods of friction and crushing. This reduces downtime caused by wear and extends the life of the components.
   
2. High Toughness and Impact Resistance
   MN22Cr2 exhibits excellent toughness and resistance to impact, making it ideal for high-load, high-intensity crushing operations. Even when dealing with hard ores, MN22Cr2 ensures reliable performance.
   
3. Extended Equipment Life
   Mantles and Bowl Liners made from MN22Cr2 material help extend the lifespan of the crushing machine, minimizing the need for frequent part replacements and reducing downtime for repairs.
   

Impact of Material Selection
Choosing the right material for the Sandvik CH660 Mantle and Bowl Liner is essential for the equipment’s overall performance. MN22Cr2 provides superior wear resistance, toughness, and impact resistance, making it an ideal material for crushing operations. By selecting the right material, mining companies can reduce maintenance frequency, optimize production processes, and increase production efficiency.
Conclusion
The Mantle and Bowl Liner of the Sandvik CH660 cone crusher are crucial wear parts that directly affect the performance and durability of the machine. MN22Cr2, a high-manganese steel, is an excellent material choice for these parts due to its outstanding wear resistance, toughness, and impact resistance. Using the right materials for these critical components can significantly extend the equipment's lifespan, reduce operational costs, and enhance crushing efficiency.
