92% Alumina Ceramic Grinding Balls with Efficient Grinding Stable and Durable Excellent Cost-Effectiveness for Industrial Applications

Product Description:

Features:

Made from 92% high-purity alumina powder as raw material, through isostatic pressing (forming pressure ≥ 180MPa) and 1600 ℃ gradient sintering process, the bulk density is stable at 3.6-3.7g/cm ³, which is more than 12% higher than ordinary alumina balls; Adding 4% zirconia composite reinforcing agent, the flexural strength reaches 38MPa, and there are no cracks in the 1.6m drop ball impact, far exceeding the industry's 1.2m impact resistance standard. The roundness error of the sphere is ≤± 0.15mm, the surface roughness Ra is ≤ 0.5 μ m, the wear rate after continuous grinding for 30 days is only 0.05%, and there is no impurity leaching, which meets the GB/T 3074.1-2017 industrial grinding standard.

Technical Parameters:

Applications:

Chemical industry, 15-25mm specification suitable for catalyst support, dye intermediate grinding, high-density to ensure uniform material fineness (D50=6-10 μ m), no impurity dissolution to ensure product purity; In the field of building materials, specifications of 30-40mm are used for grinding cement raw materials and ceramic bodies. The advantage of bulk density increases the homogenization of raw materials by 20% and the sintering qualification rate of ceramic bodies by 12%; In the field of metallurgy, the 40-60mm specification is used to process metal containing slag, with impact resistance to meet the requirements of rough grinding of slag, low wear rate to reduce slag pollution; In addition, it can also be used for grinding refractory materials and glass raw materials, with a full range of 15-60mm covering the entire process from fine grinding to coarse grinding, suitable for differentiated grinding needs in multiple industries.

Product Advantages:

Firstly, efficient grinding - with a high packing density of ≥ 3.6g/cm ³, the ball has more kinetic energy during grinding, resulting in a 28% increase in material grinding per unit time compared to ordinary grinding balls. Combined with low wear characteristics, it reduces kinetic energy loss and consumables replacement frequency; Secondly, it is stable and durable - with excellent impact resistance, it is suitable for medium and high speed grinding equipment at 20-28r/min, without the risk of cracking or shutdown, and the equipment operation rate is increased by 15%; Thirdly, excellent cost-effectiveness -92% alumina content balances performance and cost, with a price 18% lower than 95% high content products, and a comprehensive service life of 8-10 months, showing significant cost-effectiveness advantages; Fourthly, it has strong adaptability - with specifications covering 15-60mm, it can be flexibly selected according to the grinding fineness requirements, and can adapt to different material processing without changing equipment.
