Understanding the Core Challenges in Ultrafine Kaolin Handling

Ultrafine kaolin, with its extremely small particle size and high specific surface area, presents unique handling difficulties. Common issues include pipeline clogging due to moisture absorption and agglomeration, significant dust emissions that compromise workplace safety, and excessive equipment wear from abrasive particles. Operators often face reduced conveying efficiency and increased maintenance downtime, directly impacting production continuity and operational costs.

Material Characteristics of Ultrafine Kaolin

Ultrafine kaolin typically features a median particle diameter (d50) below 2 μm, a bulk density ranging from 0.4 to 0.7 g/cm³, and a moisture content sensitive to ambient conditions. Its cohesive and adhesive nature makes it prone to bridging in hoppers and sticking to pipe walls. Additionally, the material exhibits electrostatic charging during pneumatic transport, further complicating flow stability. Understanding these properties is essential for designing an effective conveying system.
