The alumina ball produced by Jingang company adopts selected high-quality raw materials, advanced molding technology and high-quality grinding media calcined by high-temperature tunnel kiln. Products with high strength, high hardness, high wear resistance, large ratio, small size, high temperature resistance, corrosion resistance, pollution-free, seismic stability and other excellent characteristics, is the best grinding medium for glaze, billet and various mineral powder processing. The products are widely used in ceramics, cement, chemical industry, glass, coating, refractory, inorganic mineral powder and other industries. They are grinding media for ball mill, tank mill, vibration mill and other fine grinding equipment. Their grinding efficiency and wear resistance rate are much better than that of common pebbles or natural pebbles.

Jingang company selects high-quality alumina as the basic raw material, with high purity, less impurities and stable quality. Kanban production is implemented, and the whole production process can be controlled and traced. In the process of product production, every step of the process has basically realized the microcomputer automatic control. According to the specific requirements of customers and the needs of the construction site, the process control of products can be adjusted in time, different specifications of products can be produced, and each batch of products can be sampled and strictly inspected. The process and result inspection ensure the stable performance and excellent quality of the finished products, and finally reach the customers Use requirements to improve the effectiveness of the whole process.
