D202275 METSO
Product Introduction
The METSO D202275 is a genuine cone crusher mantle designed for Metso Nordberg® HP Series crushers, including the HP4, HP5, HP400, and HP500 models. As a critical wear component, the D202275 mantle is the inner lining of the moving cone assembly and is directly responsible for the crushing action in high-pressure compression crushing applications. Manufactured by METSO—now operating as Metso following the merger with Outotec—this part is engineered to deliver maximum durability, consistent performance, and optimal shape control in demanding mining, quarrying, and aggregate production environments.
The D202275 is forged from high-manganese steel (Mn14Cr2 or similar), a material renowned for its ability to work-harden under impact. This means the more the mantle is subjected to crushing forces, the harder and more wear-resistant its surface becomes, significantly extending service life compared to standard steel alloys. The mantle’s precision casting and dimensional accuracy ensure a perfect fit with the crusher’s head bushing and main shaft, maintaining consistent chamber geometry for uniform product size and reduced fines generation.
Used in secondary and tertiary crushing stages, the METSO D202275 mantle plays a vital role in achieving high throughput and energy efficiency. Its design optimizes the crushing chamber profile, allowing for better material flow and reduced blockages. As an OEM (Original Equipment Manufacturer) part, the D202275 guarantees compatibility, reliability, and performance that meets the rigorous standards set by Metso for its HP Series crushers—machines known worldwide for their robustness and productivity.
Core Advantages and Technical Highlights
Superior wear resistance with high-manganese steel construction
The D202275 is cast from high-manganese steel, a material specifically chosen for its exceptional toughness and ability to harden under dynamic loading. This self-hardening property makes the mantle ideal for crushing hard rock such as granite, basalt, and iron ore, where abrasive wear is a major concern. Compared to alternative materials, high-Mn steel provides a longer service life, reducing the frequency of liner changes and associated downtime.
Precise OEM fit and chamber geometry for optimal performance
As a genuine Metso part, the D202275 is manufactured to exacting tolerances, ensuring a seamless fit with the crusher head and outer mantle (concave). This precision maintains the designed crushing chamber profile, which is critical for achieving consistent product size, high reduction ratio, and minimal recirculation load. Proper chamber geometry also reduces stress on other crusher components, such as the main shaft and thrust bearing, enhancing overall machine longevity.
Designed for HP4, HP5, HP400, and HP500 crusher compatibility
The D202275 is specifically engineered for use in Metso HP4, HP5, HP400, and HP500 cone crushers—some of the most widely deployed models in the industry. This broad compatibility makes it a versatile and reliable replacement option for operators across the globe. Whether used in a fixed plant or mobile crushing unit, the D202275 ensures seamless integration and performance continuity.
Enhanced safety and reduced maintenance downtime
The mantle’s robust design and secure mounting system minimize the risk of loosening or ejection during operation, a critical safety consideration in high-energy crushing environments. Its standardized replacement procedure allows for relatively quick changeouts during scheduled maintenance, helping to maximize uptime. When paired with genuine Metso concaves and proper crusher settings, the D202275 contributes to a balanced wear pattern and predictable maintenance cycles.
Typical Application Scenarios
The METSO D202275 is extensively used in hard rock mining operations, where it crushes materials like granite, basalt, quartzite, and copper ore in secondary and tertiary stages. In quarries producing construction aggregates, the mantle helps generate well-graded stone for concrete, asphalt, and road base, ensuring product quality and compliance with industry standards.
In large-scale mining projects, such as open-pit copper or iron ore mines, the D202275 mantle operates in high-capacity crushing circuits, where reliability and wear life directly impact production costs. Its use in mobile and modular crushing plants further demonstrates its adaptability to both permanent and temporary installations.
The D202275 is also employed in recycling applications involving concrete and demolition waste, where its impact resistance and wear properties are advantageous. In infrastructure projects, such as tunneling and dam construction, it supports on-site crushing operations, reducing transport costs and environmental impact.

Installation, commissioning and maintenance instructions
Installation preparation: Before installing the METSO D202275, ensure the crusher is locked out and depressurized. Clean the head assembly and main shaft thoroughly. Inspect the taper and threads for damage. Apply a high-temperature anti-seize compound to the mounting surface. Use proper heating methods (induction heater) to expand the mantle for a thermal fit onto the crusher head. Follow Metso’s specified torque and seating procedures to ensure secure mounting.
Commissioning steps: After installation, verify proper alignment and clearance between the mantle and concave. Set the CSS (Closed Side Setting) according to the material and desired output. Run the crusher under no-load conditions to check for vibration or abnormal noise. Gradually introduce feed material while monitoring power draw and product size. Adjust settings as needed to optimize performance.
Maintenance suggestions: Regularly inspect the D202275 for uneven wear, cracks, or movement. Monitor the crusher’s amperage and throughput as indicators of liner wear. Replace the mantle when wear reaches the safety mark or when product quality degrades. Always replace mantles and concaves as a matched set to maintain chamber symmetry. Maintain proper lubrication and sealing to prevent contamination.
