Against the backdrop of the mining and aggregates industries continuously striving for cost reduction and efficiency improvement, steel-based titanium carbide composite casting liners have officially entered commercial use. This titanium carbide inlaid liner technology successfully addresses the industry's longstanding challenges of high wear, frequent downtime, and excessive consumable costs in cone crushers by redefining the wear-resistant systems of both the mantle and破碎壁 (crushing wall). As a result, it enables comprehensive lifecycle cost management for the entire crushing system.
