Customized Cast & Machined Sizer Segments – Impact-Resistant High Manganese / Alloy Steel Crushing Teeth for Ore Sizers
At Y&J Industries, we deliver precision‑engineered components that power the mining, crushing, and mineral processing industries worldwide. Our portfolio is designed to withstand extreme mechanical stresses, abrasive environments, and heavy dynamic loads, ensuring reliable performance and reduced downtime in the most demanding operations. Within our customized Mining Machinery parts portfolio, sizer segments are the key working elements installed on crushing rolls. Every segment is fully customized – cast from high manganese steel or alloy steel, CNC machined, and finished exactly to your engineering drawings or physical samples. You define the tooth profile, material grade, and attachment method; we focus on precision manufacturing and can provide practical Design for Manufacturability (DFM) feedback to help your design transition smoothly into reliable production.
Casting & CNC Machining – Made Exclusively to Your Drawings or Samples
All sizer segments we produce are manufactured through a combined process of sand casting (or shell mold casting, depending on geometry) followed by precision CNC machining. Casting delivers the near-net tooth shape with excellent material density, while machining ensures accurate mounting features, bore dimensions, and flank surfaces. Y&J Industries is a Chinese manufacturer specializing in customized mechanical components through integrated casting, forging, and machining. For sizer segments, casting plus machining is the primary production route, allowing the cost-effective creation of complex, wear-resistant profiles.
Simply provide your complete engineering definition: 2D drawings (PDF, DWG), 3D models (STEP, IGES), or a physical sample, along with your specified material grade (high manganese steel, chromium-alloy steel, etc.) and any supplementary heat treatment or surface hardening requirements. We faithfully reproduce your segment with strict dimensional control and full material traceability. We do not offer tooth design services; however, upon request we can review your design from a DFM perspective, offering localized suggestions on casting draft, radii, or machining stock to improve castability and service life – without altering your functional intent. Minimum order quantity is not fixed; it depends on the material, process complexity, and segment dimensions. We adapt to your batch size, whether a single prototype ring or full production volumes.
Material Options – High Manganese Steel and Alloy Steel for Maximum Wear Resistance
You specify the material based on your ore characteristics and crushing conditions. We cast with full traceability:
High Manganese Steel – Offers exceptional toughness and self-work-hardening ability under impact, ideal for abrasive, high-stress applications where tooth breakage must be avoided.
Alloy Steel (e.g., chromium-molybdenum, nickel-chromium grades) – Provides a balance of strength, wear resistance, and dimensional stability, particularly suited to ores with moderate abrasiveness but high loading.
Additional treatments – including heat treatment, surface hardening, or hardfacing on wear tips – can be applied per your specification. Every heat is verified with mill certificates and mechanical testing as required.
Engineered for Efficient Reduction and Consistent Product Sizing
Sizer segments are the active crushing elements that grip, shear, and compress large ore lumps directly on the roll. Their specialized tooth profiles – defined entirely by your design – engage feed material aggressively while controlling the proportion of fines. By combining strong cutting action with precise geometry, they deliver efficient size reduction and a consistent product gradation across a wide range of materials.
Key performance characteristics manufactured into every segment:
Impact-resistant cast structure – Withstands sudden shock loads from tramp metal or hard rock without tooth fracture.
Optimized tooth geometry – Your profile ensures effective nip and fracture, minimizing over-crushing and maintaining a low fines ratio.
Accurate mounting interfaces – CNC-machined bores and contact faces guarantee secure fitting to the roll hub and correct tip positioning.
Modular design – Segments are designed per your specification for easy installation and replacement when required, supporting high crusher availability.
Together, these features make sizer segments a durable, efficient solution for modern ore crushing operations – and because every segment is built to your unique design, it integrates seamlessly with your sizer roll assembly and maintenance procedures.
