ZTA Ceramic Chute Liner
ZTA Ceramic Chute Liner is a zirconia-toughened alumina lining engineered for chute sections exposed to abrasive bulk material flow and repeated mechanical impact. The alumina matrix delivers high surface hardness, while zirconia reinforcement increases fracture toughness to withstand demanding wear environments.
Where ZTA Chute Liners Are Used
Transfer Chutes
Installed at material transfer points where falling and sliding solids create concentrated surface wear.
Feed & Discharge Chutes
Lined in feed and discharge sections subject to continuous abrasive flow and repeated particle impact.
Hoppers & Bins
Applied to internal walls experiencing high abrasive loading during material feeding, storage, and discharge cycles.
When to Select ZTA
High Impact
Specified for chute areas where bulk materials strike the lining surface with significant impact energy.
Combined Wear
Applied in transition zones where sliding abrasion and impact forces occur simultaneously during material handling.
Heavy Material Flow
Utilized in sections carrying continuous abrasive solids under sustained operational contact.
ZTA Material Composition
Alumina Matrix
Forms the primary ceramic phase, providing the hard exterior required for abrasive material handling.
Zirconia Toughening
Integrated into the crystalline structure to raise fracture toughness and inhibit crack propagation under stress.
