Henan DOMILL Abrasive Technology Co., Ltd (“DOMILL Abrasive”for short) was established in June 1993, with subsidiaries of "Yichuan Dongfeng Abrasives Co., Ltd" and "Yichuan Longquan Dongfeng Abrasives Co., Ltd", is one of the TOP10 fused alumina manufacturers in China. From furnacing, sizing, calcining and surface treating, DOMILL produces abrasive grains and powders for abrasive tools manufacturing, blasting media, refractories, industrial ceramics, lapping & polishing, fillers and additives, etc., and the products are widely used in various fields of manufacturing industry.
30+ years of experience
1000+ types of products
50,000+ tons of abrasive grains and powders
DOMILL Abrasive is the "High Quality Products of Henan Province". The quality control start from the selection of ripe bauxite.
DOMILL strategically invests in white fused alumina production plant. White Fused Aluminum Oxide is made by the fusion of controlled quality Bayer Alumina in an electric arc furnace at temperatures higher than 2000 degrees accompanied by a controlled solidification process to achieve good strength.
After 30 years of development, DOMILL abrasive is mainly used in abrasive tools manufacturing, blasting media, refractory, anti-wear, filler and polishing. These abrasive tools and media are used in almost all fields of manufacturing, including aerospace, transportation, energy, construction, automotive and so on. DOMILL Abrasive has own understanding of the application of abrasive, can meet the needs of customers, to give the most ideal choice.
Alumina Based Abrasive is mainly an abrasive containing Aluminum Oxide(Al2O3) , the Mohs hardness scale is 9.0. The common Alumina Base Abrasive includes Brown Fused Alumina, White Fused Alumina, Pink Fused Alumina, Black Fused Alumina, Monocrystalline Alumina, Zirconia Alumina and Ceramic Aluminum oxide.Read More
Calcination is a kind of abrasive processing method, of applied to Brown Fused Alumina. These may be either 1050℃ as medium temperature heat treated or 1350℃ temperature heat treated, both enhance toughness, 1350 heat more so than 1050 heat.Read More
Hardness: Resistant ability of abrasives when a compressive force is applied. Hardness are classified into scratch hardness and indentation hardness based on different modes of compressive force. Moh's hardness belongs to the former, and knoop hardness to the latter. Generally, the higher the major chemical composition content in abrasives, the higher the hardness.Read More
