Recently, our company has made significant progress in the R&D project for wear‑resistant components of crushing equipment. The next‑generation composite‑reinforced crusher tooth plate has officially completed its trial production and has entered the stage of large‑scale operational validation. Designed specifically for high‑impact, high‑wear applications in mining, metallurgy, building materials, and solid waste treatment, this product employs a composite manufacturing process that combines a high‑toughness cast matrix, a surface‑clad wear‑resistant layer, and hard‑alloy columnar teeth for reinforcement, thereby achieving comprehensive improvements in impact resistance, wear resistance, and service life.

As a critical wear component of the crusher, the toothed plate endures repeated impacts from large feed material, intense compressive forces, and abrasive wear during operation. Its performance directly affects equipment throughput, maintenance intervals, and the customer’s overall operating costs. Conventional single-material toothed plates typically struggle to balance toughness and wear resistance, leading to cracking, rapid wear, and premature failure of the tooth tips. To address these industry challenges, our R&D team has conducted extensive research and successfully developed a multi-layer composite‑reinforced toothed plate.

In terms of the matrix material, the new product is manufactured from a high‑strength, tough alloy cast steel, with a tensile strength of ≥850 MPa, a yield strength of ≥650 MPa, an impact toughness (AKV, at room temperature) of ≥35 J/cm², and a hardness maintained within the range of HB 280–320. By optimizing the casting process and heat‑treatment regimen, the internal microstructure has been significantly refined, and the overall load‑bearing capacity enhanced, ensuring that the tooth plate maintains excellent stability even under continuous impact from large ore blocks, thereby effectively reducing the risks of fracture, chipping, and spalling.

In terms of wear resistance enhancement, the company employs an advanced automated surfacing process to create a high-hardness wear‑resistant layer in the primary wear zones of the tooth plates. The surfacing layer achieves a hardness of HRC 58–63, with a single‑layer thickness of 4–8 mm and a bond strength of ≥350 MPa, delivering outstanding resistance to abrasive wear and erosion. Laboratory abrasion tests demonstrate that the wear life of the surfaced areas is 2–3 times longer than that of conventional high‑manganese steel tooth plates. Furthermore, post‑weld stress‑relief treatment and a gradient transition design ensure that the wear‑resistant layer remains intact under high‑impact loading, preventing delamination and cracking.

At the critical wear zones of the crushing teeth, the company has pioneered an innovative brazed carbide‑pillar‑tooth reinforcement technology, with targeted upgrades to the tooth‑tip area. The pillar teeth are manufactured from high‑performance tungsten–cobalt cemented carbide, achieving a hardness of HRA 88–90, a flexural strength of ≥2200 MPa, and a compressive strength of ≥4000 MPa. A high‑strength brazing process ensures a robust bond between the pillar teeth and the tooth‑plate body, significantly enhancing cutting and crushing efficiency at the tooth tips while minimizing tip rounding and dulling. In practical applications, the service life of the tooth‑tip region is expected to increase by more than threefold.

Based on simulated operating conditions and preliminary field validation, the new-generation composite‑reinforced tooth plate delivers a 80%–200% longer overall service life compared with conventional monolithic cast‑steel tooth plates. The replacement interval for each set of tooth plates is significantly extended, and equipment downtime for maintenance is reduced by more than 30%, effectively helping customers lower material costs per ton of ore and enhance the continuous operational efficiency of their equipment.

In recent years, our company has consistently invested in the R&D of high-end wear-resistant materials and critical mining components, steadfastly driving product upgrades through materials innovation. The successful launch of this composite‑reinforced crusher tooth plate marks a significant milestone, elevating our capabilities in the field of high‑performance wear parts to a new level.

Going forward, our company will continue to focus on the specific operating conditions of our customers, steadily advancing the product upgrades of our crusher tooth plates, toothed rolls, wear‑resistant liners, and other related series. By delivering products that meet even higher performance standards, leveraging cutting‑edge manufacturing processes, and providing a more comprehensive service system, we will help our industry clients achieve efficient, safe, and stable production.
