White corundum grinding wheels have a wide range of applications and a promising industry development outlook.

After years of development, the production process of white corundum grinding wheels in our country has matured and can fully meet the needs of large-scale production.
White corundum grinding wheels refer to abrasives made from industrial alumina powder as the main raw material smelted in an electric arc furnace. White corundum grinding wheels have advantages such as good cutting performance, high hardness, and environmental friendliness, and are widely used in fields such as plastic products, furniture manufacturing, and mechanical parts. Depending on the binder, grinding wheel manufacturing process, and abrasives used, white corundum grinding wheels can be divided into different specifications, including 14mm, 16mm, and 18mm white corundum grinding wheels.
According to the "2023-2028 China White Corundum Grinding Wheel Industry Market Deep Research and Development Prospect Forecast Report" released by the New Thinking Industry Research Center, the main raw material for white corundum grinding wheels is industrial alumina powder. Industrial alumina powder, also known as industrial aluminum oxide powder, appears as a white amorphous powder and has characteristics such as strong chemical stability, low production cost, and high purity, making it suitable for producing artificial abrasive white corundum. In recent years, the production of alumina in our country has maintained a steady growth trend. According to data from the National Bureau of Statistics, the production of alumina in our country reached 77.475 million tons in 2021, a year-on-year increase of 5.0%. The sufficient supply of raw materials lays a foundation for the development of the white corundum grinding wheel industry in our country.
The production of white corundum grinding wheels requires processes such as raw material crushing, acid washing, sorting, drying, roasting, grinding, and polishing. The main production equipment for white corundum grinding wheels includes ball mills, cleaning tanks, high-temperature electric furnaces, drying ovens, and ventilation boxes. The performance and quality of white corundum grinding wheels produced using different abrasives and binders vary to some extent. After years of development, the production process of white corundum grinding wheels in our country has matured and can fully meet the needs of large-scale production.
White corundum grinding wheels are mainstream products in the grinding wheel market, capable of polishing the burrs of products or equipment, and are widely used in fields such as metal components, ceramic materials, mechanical parts, and furniture manufacturing. In recent years, with the rapid economic development and the continuous improvement of the national living standards, the furniture industry has ushered in broad development space. According to statistics from the China Furniture Association, the production of furniture in our country reached 1.12 billion pieces in 2021, a year-on-year increase of 23.1%. Driven by downstream demand, the market scale of white corundum grinding wheels in our country will further expand.
There are many white corundum grinding wheel production enterprises in our country, mainly small and medium-sized enterprises. Zhengzhou Zhongxin Grinding Wheel Co., Ltd., Zhengzhou Yufa Abrasives Group Co., Ltd., Zibo Huanyu Abrasives Co., Ltd., and Shandong Luxin High-tech Industry Co., Ltd. are the main suppliers of white corundum grinding wheels in our country.
Industry analysts from New Thinking indicate that white corundum grinding wheels are widely used in many fields, and as market demand gradually releases, the development prospects of the industry will continue to improve. Benefiting from the sufficient supply of raw materials and prices remaining within a reasonable range, the production of white corundum grinding wheels in our country continues to increase. Currently, the production technology of white corundum grinding wheels in our country has matured, and the industry is gradually developing towards the mid-to-high end. With the continuous growth of local enterprises, the concentration of the white corundum grinding wheel industry in our country is expected to further increase.
