In vertical shaft impact (VSI) crushers, material is accelerated to high velocities and crushed upon impact with internal surfaces, making wear resistance critical to maintaining throughput and product quality. These plates are precision-engineered to withstand extreme wear, minimizing unplanned downtime and ensuring consistent performance in high-volume mining, aggregate, and recycling operations where equipment reliability directly impacts profitability.
Material: Forged from high-chrome cast steel (12-15% chromium content) or tungsten carbide-reinforced alloys, these materials offer superior hardness (50-60 HRC) and abrasion resistance, outperforming standard steel in high-wear environments.
Thickness: Optimized between 20-30 mm to balance weight and durability, providing sufficient material to withstand prolonged impact without excessive rotor inertia.
Weight: Upper plates (such as part number B96334135A) weigh 20.1 kg (44.3 lb), while lower plates (e.g., B96334140A) weigh 27.3 kg (60.2 lb), ensuring balanced rotor dynamics during operation.
Compatibility: Exclusively designed for the Metso B7150SE VSI crusher, featuring precision-machined mounting holes and contours that align perfectly with the crusher’s internal geometry for seamless installation.
Advanced alloy compositions incorporate chromium carbides and tungsten particles, creating a hard, wear-resistant matrix that minimizes material loss, extending service life by 20-30% compared to generic steel plates.
Strategic hardfacing with nickel-based alloys on high-impact zones further reduces erosion from high-velocity material flow, particularly in quartz-rich or abrasive ore processing.
Bolt-on design with high-tensile steel fasteners allows replacement through the crusher’s side service doors, reducing downtime from hours to minutes—a critical advantage in 24/7 production environments.
Weight-matched plate sets ensure uniform rotor balance, preventing excessive vibration that can damage bearings and other critical components.
Contoured surfaces with precision-engineered angles guide material flow, promoting uniform impact distribution and enhancing the crusher’s ability to produce cubical product shapes—a key requirement for high-quality concrete and asphalt aggregates.
High-temperature resistance up to 300°C ensures dimensional stability even when processing hot materials, such as recycled asphalt pavement (RAP) or freshly crushed volcanic rock.
Aggregate Production: Protects crushers during the production of concrete aggregates (3/4-inch to 2-inch sizes) and asphalt chips, maintaining consistent particle shape and reducing oversize material.
Mining: Handles abrasive ores including gold, iron ore, and coal, where high silica content accelerates wear on unprotected surfaces.
Recycling: Processes construction and demolition debris, including reinforced concrete and brick, where embedded steel and aggregates create mixed wear conditions.
Quarrying: Ensures reliable performance in limestone, granite, and basalt crushing, where material hardness ranges from 50 to 300 MPa on the Mohs scale.
By combining industry-leading durability with precision engineering, these wear plates are integral to maximizing the operational efficiency and lifespan of the Metso B7150SE VSI crusher, delivering consistent results in the most demanding processing environments.
