CO-NELE 150L High-Shear Mixing Granulator for Alumina Granulation

2026.4.16 | CO-NELE

Project Background
In the field of high-end ceramic materials, alumina is widely utilized in refractories, electronic ceramics, and ceramic components for lithium-ion batteries due to its exceptional high-temperature resistance, electrical insulation properties, and mechanical strength. However, practical applications of alumina powder impose extremely stringent requirements regarding particle uniformity, sphericity, and particle size control—presenting a formidable challenge for granulation equipment.
Traditional granulation processes typically suffer from the following issues:
Non-uniform particle size distribution, making it difficult to maintain within a 1mm range.
Low granulation yield (spherization rate), negatively impacting the quality of subsequent sintering processes.
Lack of process visibility, resulting in an absence of real-time monitoring capabilities.
To address these critical pain points, the client adopted the CO-NELE CRV09 150L High-Shear Mixing Granulator.
