Ceramic Balls are having excellent quality. The balls are having low water absorption, 100% survival in rapid depressurization test, high crushing strength, better impact Resistance (drop test), thermal shock resistance (quench test), very low attrition loss. Today, the balls are widely used in petroleum refining, petrochemicals, fertilizers plant, acid Plants and industrial gas industries. We Manufacture 3 types of ceramic balls with size from are low purity, medium purity and High Alumina balls respectively.
Devson Balls are having:
• Low Water absorption
• 100% survival in Rapid Depressurization Test
• Inert towards liquid water
• High Crushing Strength
• Better Impact Resistance (Drop Test)
• Thermal shock resistance (Quench Test)
• Very low Attrition loss.
• Ceramic ball Low purity (19-26 % Al2O3)
• Ceramic ball Medium purity (40-45 % Al2O3)
• High Alumina Ball (99 % Al2O3)
