High hardness HV1200 alumina ceramic grinding ball, thermal conductivity of 20 W/mK

Product Description:

Low wear alumina grinding balls focus on cost control and are suitable for continuous grinding industries such as cement and chemical. A certain cement enterprise previously used ordinary grinding balls and replenished 20 tons of balls per month (at a cost of 120000 yuan), with 2 shutdowns for ball replenishment; Switching to a monthly ball replenishment of 5 tons (cost 30000), shutting down once, saving over 1 million yuan in annual costs, and increasing raw material production by 5%.

Features:

Stable wear value ≤ 0.05% (0.03% for some models), using high-purity alumina and composite additive formula, through bi-directional pressure molding (density ≥ 3.5g/cm ³) and gradient sintering, with a surface hardness of HV1200 or above. Grinding cement raw materials for 30 days, the wear rate is only 0.04%, and the amount of debris decreases from 0.5% of ordinary balls to 0.02%. ​

Technical Parameters:

Color	White
Water Absorption	≤0.01%
Density	3.6 G/cm3
Material	Alumina Ceramic
Thermal Conductivity	20 W/mK
Shape	Spherical
Corrosion Resistance	High
Alumina Content	92%,95%
Size	13mm-90mm
Bulk Density	≥3.6 G/cm3

Applications:

In the grinding of cement raw materials, the amount of debris is ≤ 0.03%, which does not affect the calcination of clinker and helps to increase the compressive strength of clinker from 28MPa to 32MPa in 3 days; When grinding calcium carbonate in the chemical industry, the replacement cycle has been extended from 1 month to 4 months, resulting in a 2 percentage point increase in product whiteness and meeting the demand for high-end coatings. ​

Support and Services:

Company service:

Based on equipment and material parameters, calculate the replenishment cycle and dosage using professional formulas; Adjust the ball replenishment plan based on actual data, help customers optimize inventory and procurement plans, and maximize cost reduction. ​

Customer concern:

Provide testing reports for the issue of meeting wear standards; For the replenishment cycle, refer to similar customer cases (cement enterprises 30 days/time); Based on the subsequent costs, calculate the benefits of reducing debris (such as a 30% increase in filtration efficiency and a 3-fold extension of filter replacement cycle), and clearly demonstrate the comprehensive value.
