VSI & HSI Crusher Wear Parts Built to Outlast the Rock
High-chrome cast iron and manganese steel crusher wear parts engineered at our Texas foundry for maximum wear life, reduced downtime, and lower cost-per-ton in demanding crushing applications.
Crusher Wear Parts That Keep Your Operation Running
Every hour of crusher downtime costs your operation thousands in lost production. The right crusher wear parts are the difference between a plant that hits tonnage targets and one that constantly falls short. At C.L. Dews & Sons Foundry, we cast both VSI crusher wear parts and HSI crusher wear parts using metallurgy matched to your specific feed material and application.
Impact crushers are the workhorses of aggregate production, mining, and recycling operations. Whether you run a vertical shaft impactor (VSI) or a horizontal shaft impactor (HSI), the internal wear components take a relentless beating from abrasive rock, ore, and demolition material. When those parts wear out prematurely, you pay for it in unplanned shutdowns, labor costs, and missed delivery windows.
We have been casting crusher wear parts at our Texas foundry for decades. Our team works directly with plant managers and maintenance crews to dial in the alloy composition, hardness profile, and dimensional tolerances that deliver the longest possible wear life for each crusher model and feed condition.

VSI Crusher Wear Parts
Vertical shaft impact crushers rely on high-velocity rotor action to throw material against anvils, wear plates, or a rock-on-rock curtain. Every internal surface exposed to that impact stream needs to be engineered for extreme abrasion resistance. Our VSI crusher wear parts are cast in alloys that balance hardness with just enough toughness to resist fracture under repeated high-energy impacts.
Rotor Tip Inserts
High-chrome or tungsten carbide composite tips engineered for maximum material acceleration and consistent product shape.
Wear Plates & Cavity Liners
Precision-fit plates that protect the rotor body and upper/lower wear areas from abrasive feed material erosion.
Anvils & Anvil Rings
Heavy-duty anvils cast in high-chrome iron that absorb repeated high-velocity impacts without cracking or spalling.
Feed Tubes & Distributor Plates
Wear-resistant feed components that ensure even material distribution across the rotor for balanced crushing action.
HSI Crusher Wear Parts
Horizontal shaft impactors use rotating blow bars to strike incoming feed material against stationary breaker plates or aprons. The blow bars absorb enormous kinetic energy with every revolution, and the breaker plates take the rebound. Our HSI crusher wear parts are cast for the specific wear pattern each component faces, whether that is direct high-energy impact or sustained abrasive sliding.
Impact Blow Bars
Available in high-chrome iron, manganese steel, and martensitic steel. Alloy selection depends on feed abrasion index and desired wear profile.
Breaker Plates & Aprons
Thick-section castings that absorb redirected material energy. Designed with replaceable wear surfaces to extend service intervals.
Liner Plates & Side Plates
Precision-ground liners that protect the crusher housing. Cast in abrasion-resistant alloys to handle high-tonnage throughput.
Rotor End Discs & Wedges
Structural rotor components cast to tight tolerances for secure blow bar retention and balanced rotor operation at speed.
Materials & Metallurgy
Alloy selection is the single most important factor in crusher wear parts performance. We do not offer a one-size-fits-all casting. Instead, our metallurgists work with your operational data, including feed hardness, moisture content, throughput rate, and crusher speed, to specify the alloy grade that delivers the lowest cost-per-ton for your application. Our alloys meet or exceed ASTM A532 standards for abrasion-resistant cast irons.
High-Chrome Cast Iron
Our primary alloy for crusher wear parts. Chrome content from 15% to 28% creates hard chromium carbides throughout the matrix, delivering exceptional abrasion resistance in high-impact environments.
Manganese Steel (Hadfield)
Austenitic manganese steel work-hardens under repeated impact, making it ideal for blow bars and crusher liners in applications with heavy, large-feed material and extreme impact loading.
Martensitic Steel
For applications that demand a balance of toughness and hardness. Martensitic blow bars resist fracture in cold-weather operations and secondary/tertiary crushing stages.
Composite & Carbide Inserts
Tungsten carbide tips and bimetallic composites for extreme-abrasion zones like VSI rotor tips, extending wear life well beyond monolithic alloy components.
Industries We Serve
Aggregate
Production
For applications that demand a balance of toughness and hardness. Martensitic blow bars resist fracture in cold-weather operations and secondary/tertiary crushing stages.
Mining & Mineral Processing
Hard-rock mining operations crushing ore through primary, secondary, and tertiary stages require alloys matched to each stage’s specific wear conditions.
Recycling & Demolition
Concrete, asphalt, and C&D recycling operations face unpredictable feed that demands tough, impact-resistant crusher wear parts.
Why Choose C.L. Dews & Sons Foundry
When you source crusher wear parts from Dews, you are buying directly from the foundry that pours the metal, not a distributor reselling imported castings. That means faster lead times, full traceability on every heat, and direct access to our metallurgy team when you need to adjust an alloy for a new feed material or crusher configuration.
In-House Pattern & Tooling
We build and maintain our own patterns. Need a custom profile or a dimensional modification for a specific crusher model? We handle it in-house without third-party delays.
Metallurgical Engineering
Our team analyzes your worn parts, reviews your feed data, and recommends alloy adjustments that extend wear life. We treat every order as an engineering project, not just a casting job.
Quality Assurance
Every casting is tested for hardness, dimensional accuracy, and microstructure before it ships. We maintain full heat traceability so you always know exactly what alloy is in your crusher.
Domestic Production
Cast in our Texas foundry. Shorter lead times, no import uncertainty, and the ability to respond quickly when you need emergency replacement parts to keep your plant running.
