Product OverviewPyrite (FeS₂) is an ideal mineral raw material for weighbridge (floor scale) manufacturing, mainly used as counterweight filler and integral molding material. According to actual weighbridge production needs, it is mainly used in two forms: granular (20–60 mesh) for direct counterweight filling, and powder (80–200 mesh) for mixing with concrete, resin and other binders for integral molding. Due to its high natural density, moderate hardness and stable physical properties, it solves the core needs of weighbridge materials: sufficient weight, good wear resistance, easy molding and low cost. Processed through professional crushing and screening, the particle size (granular/powder) is adjustable to match different weighbridge molding processes (castable, press molding, direct filling). Compared with traditional counterweight materials (such as pig iron, lead), pyrite has obvious cost advantages while ensuring load-bearing stability, making it the preferred raw material for medium and large-scale weighbridge production in industrial, mining, logistics and commercial scenarios.

Core Advantages (Customer-Oriented, Highlight Competitiveness)

High Density for Stable Counterweight: Density 4.8–5.2 g/cm³, provides sufficient weight per unit volume, ensuring weighbridge load-bearing accuracy and stability, avoiding drift caused by insufficient counterweight.
Wear-Resistant & Durable: Mohs hardness 6.0–6.5, resistant to long-term pressure, friction and impact, extending the service life of weighbridge bodies and components by 20%–30%.
Cost-Effective Alternative: 40%–50% lower cost than pig iron, lead and other counterweight materials, greatly reducing weighbridge production costs without compromising performance.
Easy to Use & Compatibility: Granular form (20–60 mesh) can be directly filled as counterweight; powder form (80–200 mesh) has good dispersion, compatible with concrete, resin and other binders, suitable for various molding processes (castable, press molding), easy to operate and improve production efficiency.
Wide Adaptability: Suitable for all types of weighbridges (electronic, mechanical) in industrial, mining, logistics, port and commercial scenarios, meeting different tonnage (10–200 tons) production needs.

Application Scenarios

Widely used in weighbridge manufacturing and maintenance, including but not limited to:

Large-tonnage industrial weighbridge (mining, port, logistics) counterweight filling
Weighbridge body integral molding (mixed with concrete/resin to enhance weight and stability)
Weighbridge load-bearing plate, base and auxiliary component manufacturing
Maintenance and reinforcement of old weighbridges (filling counterweight gaps, enhancing stability)

FAQ

Q1: Why is pyrite suitable for weighbridge materials? A1: Pyrite has high density (4.8–5.2 g/cm³) for stable counterweight, good wear resistance to withstand long-term load, and low cost. It is easy to mix and mold with binders, perfectly matching the core needs of weighbridge manufacturing.

Q2: What particle size and form is best for weighbridge use? A2: It depends on the specific use scenario: 20–60 mesh (granular) is suitable for direct counterweight filling, simple and efficient; 80–200 mesh (powder) is for mixing with concrete/resin for integral molding. We can customize the particle size and form according to your weighbridge molding and filling process.

Q3: How does pyrite compare with pig iron as a weighbridge counterweight? A3: Pyrite has similar density to pig iron but 40%–50% lower cost, and better wear resistance. It is easier to mix with binders for integral molding, reducing production steps and costs.

Q4: Can pyrite be used for all tonnage weighbridges? A4: Yes, it is suitable for 10–200 tons of electronic, mechanical and industrial weighbridges, and can be adjusted in dosage and particle size according to the weighbridge tonnage and structure.
