Highlights

• Construct equivalent non-spherical particles to study liquid bridge breakage.

• Particle size and liquid bridge volume influence liquid bridge fracture.

• Solid–liquid contact area governs the magnitude of liquid bridge force.

• Liquid bridge fracture is dictated by edge effects and contact angle hysteresis.


Abstract

This study investigates liquid bridge force and fracture behavior in non-spherical wet particles using four equivalent morphological models (ellipsoid, cuboid, oblate cylinder, prolate cylinder) to represent coal particles. The effects of particle size, liquid volume, immersion depth, and kaolinite suspension were examined. Results show that increasing particle size from 3 mm to 9 mm raises the maximum liquid bridge force of cuboid particles from 520.38 μN to 11,275.30 μN. Peak forces occur at liquid volumes of 1–5 μL, with cuboid particles exhibiting the largest variation (1328.87 μN). Greater immersion depth extends fracture distance by up to 25% but minimally affects peak force. In kaolinite suspensions, fracture distance stabilizes at 6 mm while data dispersion increases. The solid–liquid contact area dominates the liquid bridge force, and fracture is controlled by edge effects and contact angle hysteresis. These findings aid optimization of non-spherical wet particle separation.
