Import Alkaline Ceramic Ball For Water Filter — Buy in wholesale FOB from Supplier in China

Zhangqiu Longxin Corundum Products Co., Ltd supplies alkaline ceramic balls in graded sizes from 1 mm to 20 mm, with a beige appearance and claimed magnesium content of forty percent. The material exhibits an oxidation-reduction potential (ORP) of minus 50 mV maximum and raises water pH to a maximum of 10, functioning by slow dissolution of mineral content into filtered water. Density ranges from 1.35 to 1.40 g per cubic centimetre, with bulk density at 0.74 to 0.78 g per cubic centimetre, figures that align with porous ceramic structures designed for extended contact time in filtration columns. The company is based in Jinan, Shandong Province, with postal code 250200, though buyers should confirm current production capacity and whether the balls are sintered or extruded, as this affects mechanical durability and dissolution kinetics.

The ceramic matrix is typically formulated from magnesite or dolomite-derived materials combined with clay binders and fluxes, fired to achieve controlled porosity and specific surface area. Standard industry practice for functional ceramic balls includes testing for compressive strength, attrition loss during tumbling, and leachable heavy metals under NSF/ANSI 61 or similar potable water contact standards. Zhangqiu Longxin claims a service life of at least one year and anti-bacterial properties, both of which require third-party validation, as anti-bacterial claims in water treatment are regulated in many import markets. The nutrient release function, cited as more than twenty kinds, should be specified by element and concentration range, since indiscriminate mineral addition can exceed safe drinking water limits for elements such as magnesium, calcium, or trace metals.

These balls suit manufacturers of domestic countertop filters, commercial alkaline water systems, and industrial wastewater pH adjustment units. The 1 mm to 20 mm size range covers applications from precision cartridge inserts to loose media in large pressure vessels. Zhangqiu Longxin packs in twenty-kilogram woven bags with one thousand kilograms per pallet, a configuration suited to sea freight consolidation. Buyers should note that no MOQ, price, lead time, or certification details appear in the source data, so all commercial terms must be confirmed directly with the supplier. The Shandong location offers rail and port access via Qingdao, approximately three hundred kilometres east, a logistics detail relevant for container planning.

Zhangqiu Longxin Corundum Products Co., Ltd operates from Jinan City, Shandong Province, postal code 250200, a region with established refractory and ceramic manufacturing clusters. The company name references corundum, implying aluminium oxide-based product lines, yet this listing focuses on magnesium-rich alkaline ceramic balls, suggesting either a diversified portfolio or a trading division. Trust tier is harbour with zero percent response rate and zero logged response hours, indicating potential communication challenges that buyers must anticipate. No employee count, revenue, year of establishment, or factory certification appears in the profile, preventing verification of production scale or quality-system maturity.

The supplier's product description emphasises functional claims, pH restoration, mineralisation, anti-bacterial action, and odour removal, without referencing supporting standards or test protocols. Buyers should treat these as marketing statements pending documentary evidence. The Jinan location provides rail connectivity to Qingdao Port and road access to Tianjin and Shanghai alternatives, logistical options to explore once contact is established. The absence of any client references, case studies, or export history in the visible profile means due diligence must focus on factory audit, sample testing, and third-party certification rather than reputation verification.
