WearTech offers alumina grinding balls and wear ceramics in 92%, 95%, 97%, and 99% Al₂O₃ content grades. Each grade is engineered for specific wear conditions — 92% alumina is ideal for standard grinding applications, while 97-99% high-purity alumina is suited for extreme abrasion and contamination-sensitive processes. We recommend the optimal grade based on your material hardness, particle size, and throughput requirements.

Our standard MOQ is 100 kg for alumina grinding media (balls, beads, cylpebs) and 50 pieces for custom ceramic liners and tiles. For first-time orders, we accept smaller trial orders of 50 kg to allow customers to test product performance before committing to bulk purchases. Contact us at wangxia@weartech-pro.com for specific product MOQs.

Standard products such as alumina grinding balls and stock-size tiles ship within 7-15 working days. Custom-engineered products including shaped ceramic liners, ceramic-rubber composites, and hydrocyclone systems require 15-30 working days depending on complexity. Urgent orders can be accommodated — contact us to discuss expedited production timelines.

Yes! WearTech provides free samples for qualified buyers. We send representative samples of grinding media, wear tiles, and ceramic linings so you can evaluate hardness, wear rate, and fit before placing a production order. Sample shipping is complimentary for orders above our MOQ threshold. Request samples by emailing your application details to wangxia@weartech-pro.com.

WearTech is ISO 9001:2015 certified for quality management. All products undergo strict in-process quality control including dimensional inspection, hardness testing (Rockwell/Mohs), wear resistance testing, and chemical composition analysis via XRF spectroscopy. We provide third-party inspection reports (SGS, TÜV) upon request and support customer on-site quality audits.

Absolutely — custom engineering is our core strength. We manufacture ceramic products to your exact drawings, CAD files, or application specifications. Our engineering team provides free design consultation, material selection guidance, and dimensional optimization. Custom capabilities include ceramic-lined pipes (DN50-DN2000), shaped wear tiles, cyclone liners, and ceramic-rubber composite panels.

All products are carefully packaged to prevent damage during ocean freight and air transport. Grinding media is packed in 25 kg PP woven bags on fumigated wooden pallets. Ceramic tiles and liners are wrapped in foam separators, packed in plywood crates, and secured with steel straps. Heavy items use reinforced wooden cases. Every package includes product labels, batch numbers, and packing lists.

WearTech accepts T/T (bank wire transfer), L/C at sight, Western Union, and PayPal for sample orders. Standard terms are 30% deposit upon order confirmation, with 70% balance paid before shipment against copy of B/L. For established customers, we offer flexible terms including net-30 payment or D/P at sight.

WearTech ceramics serve 6+ major industries: mining (ore grinding, slurry transport, hydrocyclones), power generation (coal mills, ash handling, FGD systems), steel & metallurgy (sintering plants, blast furnace feed), petrochemical (catalyst support, acid-resistant pipes), cement (raw mill grinding, clinker handling), and ports (bulk conveyors, ship unloaders). Our products withstand temperatures up to 1,800°C.

Alumina grinding balls (92-99% Al₂O₃) offer excellent wear resistance at a lower cost — ideal for cement, mining, and ceramics. Zirconia beads (Y-TZP, HRA 90+) provide zero contamination and ultra-fine grinding down to sub-micron sizes — essential for electronics, pharmaceuticals, and high-end coatings. We help you select the right media based on your material, target fineness, and contamination tolerance.

WearTech alumina ceramic parts typically last 10-200× longer than manganese steel equivalents. In high-abrasion slurry pipelines, our 95% alumina tiles last 50-80× longer than AR400 steel. In dry grinding, alumina balls last 5-10× longer than natural flint pebbles. This translates to significantly lower total cost of ownership despite higher initial investment.

Yes — we export to 40+ countries across Asia, Europe, the Americas, Africa, and the Middle East. We handle all logistics including export documentation, customs clearance, and door-to-door delivery via FOB, CIF, or DDP terms. Shipping from Qingdao port, ocean freight takes 15-35 days depending on destination. Air freight is available for urgent sample deliveries.
