SSiC Grinding Barrel


Silicon carbide sand mill lining, AKA grinding barrel, with high hardness, wear-resistance, high-temperature resistance, and high thermal conductivity, is a newly researched silicon carbide wear-resistant product that serves 5-10 times longer than the ordinaries. It guarantees the efficiency and quality of the grind materials by its fast conduct of the heat and performs excellently in resisting the acid and alkali corrosion of certain grind materials.

Oustek’s grinding inner barrel adapts high refractory silicon carbide powder of purity up to 98.5%. Supported by isostatic pressing, net size sintering and mechanical finishing technique, it produces grinding barrel with density up to 3.1kg/m³, smooth barrel wall, minimized tolerance that guarantees the particles fine and evenly processed.


Mainly for grinding in paint and coating, cosmetics, food, daily chemical industry, dye, ink, medicine, magnetic recording material, ferrite, and photographic film, etc.


  • Extremely low wear and tear to prevent material pollution.

Isostatic Pressing

With self-own isostatic pressing equipment, all products use isostatic pressing technology to make the green body uniformly stressed, the density distribution is uniform, and the product performance is greatly improved. There are incomparable advantages when molding complex shapes, elongated products, large-sized products, and precision-sized products.
