Core Overview
High specific gravity pyrite ore is professional heavy aggregate for counterweight concrete and solid counterweight blocks.
With specific gravity 3.8–4.6, graded particle sizes and priority to high density over sulfur index, it is widely used for crane, elevator and washing machine counterweight manufacturing. Stable physical property, low water absorption, perfect replacement of traditional heavy aggregate.

FAQ
Q1: Why use pyrite for counterweight concrete?
A1: It features high specific gravity 3.8–4.6, stable bulk density, complete particle grading, ideal for making compact and heavy counterweight blocks.
Q2: Why sulfur content only ≥25%?
A2: For counterweight usage, high specific gravity is the first priority. Sulfur ≥25% meets basic stability requirement without affecting concrete solidification and long-term use.
Q3: What particle sizes are available?
A3: We supply 0–1mm fine grade, 1–15mm medium grade and 15–50mm coarse grade, can be proportioned according to customer concrete formula.
- Packaging Options: Available in 25 kg bags, ton bag, or custom packaging as per customer requirements. All packaging is durable and designed to prevent moisture ingress.
