Product Description:
Designed specifically for industries such as chemical, building
materials, and metallurgy that balance grinding efficiency and
stability, with 92% alumina content as the core substrate, combined
with a stacking density of ≥ 3.6g/cm ³ and excellent impact
resistance, it solves the pain points of insufficient grinding
energy and weak impact resistance caused by low stacking density of
ordinary grinding balls, which are prone to cracking. After a
certain building materials enterprise adopted its grinding cement
raw materials, the output of a single ball mill increased from 35
tons to 45 tons, the crushing rate decreased from 10% to 1.8%, and
the ball replenishment cycle was extended by three times. This not
only ensures the quality of grinding but also reduces comprehensive
costs, adapting to the large-scale production needs of multiple
industries.
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.

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.
