Corundum Heat Carrier Balls
Aluminum Oxide (Al₂O₃) · Corundum Balls · Alumina Heat Carrier Balls · Ceramic Heat Transfer Media · Alumina Spheres
Corundum heat carrier balls are dense ceramic spheres manufactured primarily from high-purity aluminum oxide. They are engineered for high-temperature applications where thermal stability, heat capacity, and wear resistance are critical. The material is extremely hard, dense, and highly abrasive, making equipment durability a primary consideration in bulk handling systems. KWS designs heavy-duty conveying systems capable of handling corundum media while minimizing wear, breakage, and maintenance requirements.
