HPGR retrofit solutions and Metso Barmac B7150SE VSI wear parts are at the center of a newly announced market expansion strategy by Zigong Rettek New Materials Co., Ltd. (Rettek), a professional manufacturer of wear-resistant carbide tools and components. The initiative marks the company’s formal push into high-demand mining and aggregates markets where equipment durability, uptime, and total cost of ownership are critical.
As global mining and construction operations continue to scale up production while processing increasingly abrasive materials, demand is rising for advanced wear solutions that outperform conventional steel components. Rettek’s strategy focuses on leveraging high-wear tungsten carbide technology to upgrade High Pressure Grinding Rolls (HPGR) and high-capacity VSI crushers, offering operators longer service life and improved operational stability.
HPGR Retrofit Solutions Target Extended Roll Life
HPGR retrofit technology using tungsten carbide studs has become a priority for operators seeking to maximize the return on existing grinding assets. HPGR systems operate under extreme pressure, subjecting roll surfaces to severe abrasion and impact. Traditional steel studs often wear rapidly, resulting in frequent maintenance shutdowns and rising operational costs.
Rettek’s HPGR retrofit solution embeds high-wear tungsten carbide granules and studs directly into roll surfaces, significantly improving abrasion resistance. Field applications indicate that carbide-studded rolls can achieve two to five times longer service life compared with steel-only designs. This improvement translates into reduced downtime, more consistent grinding performance, and lower long-term maintenance costs.
According to Rettek, the growing adoption of HPGR technology worldwide makes retrofit upgrades a strategic opportunity. Rather than replacing entire roll assemblies, operators can extend equipment lifespan while improving wear resistance through carbide retrofitting.
“HPGR retrofits are no longer viewed as a simple repair solution,” a Rettek representative stated. “They are now a performance-driven upgrade, and tungsten carbide is the key material enabling that shift.”
Metso Barmac B7150SE VSI Applications Strengthen VSI Market Focus
Metso Barmac B7150SE VSI wear parts, including carbide rotor tips and inserts, represent another core pillar of Rettek’s expansion strategy. The B7150SE VSI is widely used in aggregates, mining, and industrial sand production due to its rock-on-rock crushing principle and ability to produce highly cubical material.
Operating with rotor speeds ranging from approximately 1,100 to 2,100 rpm and processing feed sizes up to 45 mm, the Barmac B7150SE places intense wear demands on internal components. Rettek’s tungsten carbide rotor tips are designed to withstand high-impact and abrasive conditions while maintaining consistent crushing efficiency.
By improving wear resistance in critical areas, Rettek’s VSI carbide solutions help stabilize output quality, support continuous operation, and minimize unplanned stoppages in high-throughput environments. This makes them particularly attractive for industrial users running capacity levels of up to hundreds of tons per hour.
Integrated Manufacturing Ensures Consistent Carbide Quality
A key differentiator behind Rettek’s HPGR and VSI wear solutions is its fully integrated manufacturing model. Based in Zigong, Sichuan — a globally recognized carbide production hub — Rettek controls the entire production chain, from alloy raw material preparation and batching to pressing, vacuum sintering, tool design, and automated welding.
This end-to-end control allows Rettek to tailor carbide compositions to specific crushing and grinding applications while maintaining strict quality consistency. Advanced brazing and welding processes further ensure reliable bonding performance under extreme operating conditions.
“Full in-house control gives us the flexibility to respond to market needs without sacrificing quality,” the company noted. “It also allows us to optimize production costs while delivering long-lasting carbide solutions.”
Global Market Expansion Backed by Proven Performance
Rettek’s carbide wear parts are currently supplied to customers in more than 10 countries, with applications spanning mining, aggregates, snow plow systems, and industrial crushing equipment. The company’s renewed emphasis on HPGR carbide studs and VSI crusher wear parts reflects growing international demand for durable, high-performance alternatives to traditional wear materials.
Rather than competing solely on price, Rettek’s market strategy emphasizes lifecycle value — reducing downtime, lowering replacement frequency, and improving operational efficiency for end users. This approach aligns with industry trends toward sustainability and cost control, particularly in energy-intensive crushing and grinding processes.
Looking Forward
With the launch of its HPGR retrofit and Metso Barmac B7150SE VSI-focused strategy, Rettek positions itself as a specialized carbide solution provider for modern mining and aggregates operations. By combining advanced tungsten carbide materials, integrated manufacturing, and application-driven design, the company aims to support customers facing increasingly harsh operating conditions.
As demand for high-efficiency crushing solutions continues to grow, Rettek’s message is clear: longer wear life, fewer shutdowns, and reliable performance are achievable through the right carbide technology — and HPGR retrofits and VSI upgrades are where that transformation begins.
