3-7 days for spot goods; Customized delivery time to be negotiated by both parties.High-alumina balls (92-95 grade) are suitable for the ultra-fine grinding of high-end raw materials in the ceramic field, such as precision ceramics and electronic ceramics. With a low wear rate, they ensure the purity of raw materials and grinding efficiency. Medium-high alumina balls (75 grade) are suitable for the grinding of ordinary ceramic raw materials like architectural ceramics and daily-use ceramics. They balance hardness, wear resistance and cost, meeting regular grinding needs.
