75% Mid-high Microcrystalline Alumina Ceramic Grinding Ball, Diameter 60mm, High Density/Super Wear Resistance


HQ75 series are made by solid granulation and micro-powder. Special structure makes high bulk density, high strength, good resistance to abrasion, no corrosion and no pollution, high grinding efficiency, long service life and no contamination to the material as well. HQ75 series microcrystalline alumina ball is an excellent Impact and grinding balls for the all-ceramic factory. As a professional microcrystalline alumina ball manufactory, we are not only focused on wear resistance but also offering the technical grinding solutions. It is suitable for ball mill and grinding media in ceramics, cement, paint, refractory materials, inorganic mineral powder, and other industries.


High Density Aluminum Oxide Ball / Yellowish Ceramic Grinding Media 


We studied a special powder which makes microcrystalline structure showing seashell texture for our balls, process 50mm, 60mm by pressing machine which we devise by ourselves, rolling technology for 40mm, 30mm, 25mm, 20mm,15mm,10 mm and so on. Fired at high temperature in the tunnel kiln more than 80 hours. That makes more regular shape before and after use in ball mill. The secret of lower wear resistance is the material and process. With huge competition with the famous European brand in this area.


This alumina microcrystalline ball is the same wear resistance as normal 93% alumina ball with great price competition, it’s the best choice for the ceramic plant which wants to reduce the production cost. It would not only save the electric cost because it improves grinding efficiency and reduces the grinding time but also save the cost of purchase normal 68% alumina ball, 75% alumina ball, 85% alumina ball and 92% alumina ball. 


High Density Aluminum Oxide Ball / Yellowish Ceramic Grinding Media 
Suitable for industrial ceramics, ceramic capacitors, ceramic tiles, sanitary ware, etc.
Grinding, mixing, crushing and other processes of mineral raw materials.
  1. High-density smooth surface, near-perfect roundness for higher grinding efficiency.
  2. Excellent wear resistance and high impact to save your operating costs and reduce pollution.
  3. This product is available in a variety of sizes and sizes and is suitable for a wide range of grinding conditions through scientific matching. The products are widely used in the ceramic industry, refractory material, pharmaceutical, mine industry, etc. The advantages of this product are super hardness, high density, low wear loss, regular shape, and good corrosion resistance.
  4. HQ75 products made with high-tech processes of micro-powder molding and hollow granulation. The alumina balls and bricks of the microcrystalline structure sintered in the tunnel kiln has a higher degree of porcelain, which results in higher wear resistance
