Import Alumina Grinding Ball — Buy in Bulk from Supplier in China

This alumina grinding ball from Zibo Vanna Trade Co., Ltd. is engineered for wet grinding applications, with an Al2O3 content of 92% and a Mohs hardness rating of 9. The media is designed for use in high-speed stirred grinding mills and ball mills, serving as an abrasive medium for ceramic raw materials, glaze materials in ceramic factories, cement factories, and enamel factories. Its high density, hardness, and wear resistance translate to superior grinding efficiency and minimal material contamination during processing.

The balls are manufactured for both wet and dry grinding methods, with the wet grinding process requiring a final assembly volume of 55% in ball mills. The empirical formula for charging alumina balls is provided as M=3.14*R²*D*L*25%/1000, where M is the charged quantity, D is the ball density, R is the ball mill radius, and L is the ball mill length. For dry grinding, the media is optimized for low toughness and wear to prevent pollution of raw materials, with the ball-to-material ratio adjusted based on the hardness and coarseness of the raw material.

Primary applications include ceramic production, glass manufacturing, and chemical processing industries where non-contaminating, high-efficiency grinding is critical. Buyers in these sectors source the balls for their ability to maintain structural integrity under heavy loads and resist breakage. The product is shipped from Zibo City, Shandong Province, and is available for bulk orders with specifications tailored to the ball mill dimensions and intended grinding method.

Zibo Vanna Trade Co., Ltd. is based in Zhangdian District, Zibo City, Shandong Province, China, operating from China Resources Building on Jinjing Avenue. The company is classified as an imported-tier supplier with a harbor trust tier, indicating a verified business presence in the region. Its focus lies in providing ceramic materials and grinding media for industrial applications, with a specific emphasis on alumina-based products.

The supplier’s profile does not list a response rate or average response time, which suggests buyers should initiate contact directly for inquiries. The company’s description highlights its specialization in alumina grinding balls for high-efficiency grinding, with technical details provided for both wet and dry grinding methods. No additional claims about certifications, client base, or production capacity are made beyond what is explicitly stated in the listing.
