Import 75mm Alumina Packing Ball — Buy in wholesale FOB from Supplier in China

The 75mm alumina packing ball from Zibo Win-Ceramic Material Co. Ltd is a spherical ceramic media engineered for high-temperature, high-pressure industrial reactor systems. Manufactured from high-purity alumina, these 75mm diameter spheres serve as structural packing and catalyst support within hydrocracking, refining, CRCC, isomerizing, and demethylating systems across petrochemical and natural gas processing plants. The source description confirms primary function: increasing gas or liquid distribution uniformity while protecting mechanically weaker active catalysts from crush forces and thermal shock.

Alumina packing balls in this size class typically exhibit bulk densities between 1,500 - 1,800 kg/m³ and alumina content ranging from 92% to 99% depending on grade, though the listing does not specify exact purity for this batch. The material confers inherent resistance to strong acid corrosion, thermal vibration, and sustained pressure cycling, properties critical to reactor longevity. Zibo Win-Ceramic's location in Shandong Province, a recognised Chinese ceramic manufacturing cluster, suggests access to established raw material supply chains and sintering infrastructure for alumina ceramics.

Buyers for this product are predominantly petrochemical EPC contractors, refinery maintenance teams, and catalyst system integrators requiring reliable tower packing for new builds or turnarounds. The supplier's Harbor trust tier and 0.00% response rate signal an unverified engagement history, so direct confirmation of current production capacity, available alumina grades, and test certificates is essential before contract. Standard trade terms for Chinese ceramic exports typically involve FOB Qingdao or Shanghai with containerised shipment.

Zibo Win-Ceramic Material Co. Ltd is located at No.22, Changguo Western Road, Zhangdian District, Zibo, Shandong Province, 255000, China. The supplier holds a Harbor trust tier, which represents an entry-level verification status on the platform with no active response signals. The 0.00% response rate and zero average response hours indicate that no buyer enquiries have been answered through the platform channel, so direct outreach via the listed Shandong address or alternative contact methods is necessary to assess operational readiness.

The company profile does not disclose founding year, employee count, revenue, factory floor area, specific clientele, or ISO certification status. What the listing does state is a product focus on alumina ceramic packing media for heavy industrial reactor applications, suggesting specialisation in structural ceramics rather than general commodity trade. Buyers should request a company profile, quality management system certificates, and reference installations before advancing to sample or trial orders.
