Top/Bottom Wear Plates for Sandvik VSI Crusher

Product Overview

In Sandvik VSI crushers, these plates shield the crusher’s frame and rotor housing from the constant barrage of high-velocity material—preventing costly structural damage while maintaining optimal material flow paths. Constructed from high-chrome cast steel with strategic tungsten carbide reinforcements, they deliver targeted wear resistance where it matters most: the top plate’s impact zone and the bottom plate’s sliding contact area. This specialized design ensures balanced wear across components, reducing maintenance frequency and extending overall crusher lifespan.

Product Specifications

Material Construction: Plates cast from high-chrome cast steel (18-22% chromium) with tungsten carbide inserts (WC ≥80%) brazed into high-wear zones, achieving 60-65 HRC hardness in critical areas.

Thickness Optimization: Top plates feature 25-40 mm thickness (thicker at impact points) to absorb initial material impact, while bottom plates are 30-50 mm thick to withstand sliding abrasion from cascading material.

Weight Distribution: Top plates weigh 25-60 kg (55-132 lb); bottom plates 35-80 kg (77-176 lb), with balanced weight distribution to prevent frame stress.

Model Compatibility: Precision-engineered for Sandvik VSI crushers including CV128, CV229, and CV320, with mounting dimensions matching OEM specifications for drop-in installation.

Features

Targeted Wear Protection:

Tungsten carbide inserts in the top plate’s impact zone extend service life by 20-30% compared to all-steel plates, withstanding direct hits from uncrushed feed material .

The bottom plate’s high-chrome matrix resists sliding abrasion, maintaining a smooth surface for material flow even after prolonged contact with abrasive aggregates.

Flow Optimization:

Computer-aided design (CAD) contoured surfaces guide material into the rotor with minimal turbulence, reducing fines generation by 15% and improving cubical particle shape .

Tapered edges on bottom plates prevent material trapping, eliminating “dead zones” that cause uneven wear and blockages.

Structural Reinforcement:

Reinforced ribbing on plate backsides enhances rigidity, preventing warping under thermal stress and maintaining dimensional stability at operating temperatures up to 300°C (572°F).

Bolt holes reinforced with steel bushings distribute clamping force evenly, preventing fastener pull-out under vibration.

Maintenance Efficiency:

Bolt-on design with high-tensile steel fasteners (10.9-grade) allows replacement through side service doors, reducing downtime by 50% compared to welded plates .

Weight-matched plate sets ensure balanced rotor loading, reducing vibration and extending bearing life in the crusher assembly.

Applications

Concrete Aggregate Production: Protects crushers producing 3/8-inch to 1.5-inch aggregates, where particle shape uniformity is critical for concrete strength.

Iron Ore Processing: Withstands abrasion from high-silica iron ores, maintaining performance in primary and secondary crushing stages.

Construction Waste Recycling: Handles concrete debris and asphalt, resisting impacts from embedded steel and aggregate fragments.

Basalt Quarrying: Ideal for processing hard, abrasive basalt used in road construction, where wear rates on standard plates are typically high.

These wear plates combine durability engineering with flow dynamics optimization, ensuring Sandvik VSI crushers deliver consistent performance and reduced maintenance costs in the most demanding applications.
