The cyclone separator is a critical piece of equipment that utilizes centrifugal force for solid-liquid separation and classification, and is widely used in mining, metallurgy, coal, petrochemical, and environmental protection industries. During operation, the high-speed rotating solid-liquid two-phase flow generates continuous and severe impact and abrasion on the internal walls, particularly at the feed inlet, cone section, and apex discharge port. This wear not only causes shell thinning and structural failure but also reduces separation accuracy and classification efficiency due to increased internal surface roughness, ultimately significantly shortening equipment service life and driving up maintenance costs. Consequently, equipping cyclones with high-performance wear-resistant liners is a core technical measure to ensure their long-term, stable operation. Wear-resistant ceramic materials have become the ideal choice for cyclone liners due to their high hardness, excellent wear re...
