Our factory produces ballast steel shot with a drainage density of 7.5, weighing 4.8 tons per cubic meter. The eight treasure porridge boxes weigh 1800G, and are widely used in casting sand boxes, coal feed port ground hardening, bridge pavement hardening, and bridge ballast. Also for mechanical ballast, mining gold淘金, elevator counterweights, and sports equipment industries.

Gravel ballast, primarily used for weighting engineering machinery, ships, bridges, and other products. Mainly used in fields such as casting, forging, machinery, metallurgy, heat treatment, steel structures, grid structures, containers, ship repair and construction, bridges, mines, etc., for sand removal, rust removal, reinforcement, shaping, stress relief, and surface cleaning and painting of various profiles; pre-treatment of roughness (texturing) before electroplating, stone cutting, magnet ball casting, as an additive for heavy concrete and blast furnace refractory materials to enhance its wear resistance, high-temperature resistance, erosion resistance, electrostatic shielding, radiation protection, oil well filter drums, ballast, etc.

Our company specializes in producing casting sand and steel shot. The ballast sand is made from this waste material, with a specific gravity of about 7.5 tons per square meter. We can also produce ballast sand with appropriate specific gravity according to customer requirements. Color: Brown, Specific Gravity: Above 4.5g/cm³. This product is also suitable for washing machine accessories casting blocks, casting rings, guard blocks, balancing blocks, steelmaking, ironmaking. Available in block, polygonal shapes, powdered, granular forms. Sand-filled ballast blocks.
