95% Alumina Ceramic Dry Grinding Balls
Description
Technical Parameters
Products Description
95% alumina ceramic dry grinding balls are made from high-purity alumina raw materials through optimized isostatic pressing and high-temperature sintering. They have a dense corundum structure, a Mohs hardness of 9, ultra-low dry wear loss, and are designed to withstand continuous high-speed impacts in dusty dry environments. It avoids debris and dry powder contamination during operation. Stable physical properties and long service life, widely used in industries such as cement, mining, ceramics, glass, and refractory materials. This product can help factories reduce maintenance costs and significantly improve grinding efficiency.
Advantages
1. Impact resistance and crack resistance
Thanks to our formula and the dense crystal structure of alumina, 95% alumina ceramic dry grinding balls can withstand continuous high-speed collisions in large dry ball mills. During long-term operation, the breakage rate is almost zero, avoiding equipment blockage and unexpected shutdowns caused by medium breakage. It is much more durable than low-grade ceramic balls that are easily broken under strong impact.
2. Ultra low dry wear and tear, extending service life
In the scenario of dry grinding of cement raw materials and ores, its service life is twice as long as ordinary ceramic balls and three times longer than steel balls. Greatly saves labor costs for sorting and replacing grinding media in the workshop.
3. Significant energy-saving effect
The high-density structure reduces the total load of the ball mill by 20%. In actual cement production, the electricity consumption per ton of finished materials has been reduced by more than 15%. For large continuous production lines, this energy-saving effect brings significant long-term cost savings.
4. Uniform grinding and optimization of particle size distribution
The smooth spherical surface ensures stable collision and friction. The particle size of the ground dry powder is uniform, effectively improving the quality of cement, ceramics, and glass products.
Application
1. Cement and building materials industry
It is the most widely used field. Used for dry grinding of cement clinker, raw ore, and additives. 95% alumina ceramic dry grinding balls optimize cement particle size distribution while saving mill power and improving the overall quality of cement products.
2. Glass manufacturing industry
Used for fine dry grinding of quartz sand and feldspar. Low wear avoids color difference in glass and is suitable for daily and industrial glass production lines.
3. Mining and metallurgical industry
Used for dry processing of various ores and metallurgical auxiliary materials. Excellent wear resistance is suitable for long-term grinding of high hardness ores, reducing medium loss in the beneficiation production line.
4. Refractory material industry
As the preferred medium for refractory powder grinding. High alumina content will not introduce impurities, protecting the high-temperature performance of finished refractory materials.

Product specifications, customization, and packaging
Our standard size range is 13mm to 90mm, covering small experimental ball mills, medium production mills, and large industrial continuous mills.
We provide comprehensive customization services: we can produce non-standard sizes beyond the conventional range and adjust formulas for ultra-high impact working conditions. For customers with strict dimensional tolerance requirements, we can customize products according to their requirements.
In terms of packaging, we have fully considered the dusty characteristics of drying workshops and long-distance transportation. For orders with small quantities, use 25kg dust-proof woven bags; Large scale orders are reinforced with 1-ton waterproof container bags and pallets. Packaging can also be customized according to customer requirements, and all packaging is tightly sealed to prevent dust leakage and moisture absorption. We also offer mixed size packaging to meet the layered filling needs of football grinders.
FAQ
Q1: What is the difference between 95% alumina ceramic dry grinding balls and wet grinding ceramic balls?
A1: The formulas and sintering processes of these two products are different. The dry grinding ball has been optimized for high-speed impact and dry friction, while the wet grinding ball has added anti hydration components, which can soak the mud for a long time. The use of wet balls in dry mills can easily lead to cracking due to insufficient impact resistance.
Q2: What is the minimum order quantity? Do you provide free samples?
A2: The minimum order quantity for bulk orders is 500kg-1 ton. We provide free samples for dry grinding tests.
Q3: Will the product generate a large amount of dust during operation?
A3: No. The ultra-low wear loss and smooth surface greatly reduce the generation of dust, improve the on-site working environment, and reduce the load of dust removal equipment.
Q4: Which types of ball mills are compatible with this product?
A4: Suitable for all mainstream horizontal, vertical, and vibrating dry ball mills. We will match the most suitable size based on your factory model.
