• be of combined structure (not less than 90% of aluminium oxide (Al2O3) and silicon dioxide(SiO2). Thus the max silicon dioxide (SiO2) content shall not exceed 80 % of SiO2/Al2O3 weight ratio;
• be tested for water adsorption according to ASTM C-830, thus adsorbed water quantity should not exceed – 0,9 % mass;
• be manufactured from the material for operating temperatures up to 980°C;
• be manufactured in a ball shape, thus the ratio of the max ball diameter to the min ball diameter shall not exceed 1,2;
• have bulk density not less than 1360 kg/m3;
• have high scuffing and crushing proofness, fracture strength;
• be transported and stored in leakproof barrels and by transportation ceramic balls must be put into polypropylene thick-walled bag inside a tank;
• before loading into a barrel balls must be sifted for removal of broken pieces, breakage and products of a smaller and larger DN.

HuaMing alumina ceramic grinding beads are quite hard and spherical so waste less energy in rounding particles.  Ceramic ball has low friction and low wear rates, which means it achieves high grinding efficiency at a lower cost for coarse feeds.

Grinding media like steel, the outside is quite hard but the inside is softer so it wears a lot faster, whereas ceramic media has good mechanical integrity and maintains this characteristic as it wears.

In addition, ceramic media does not chemically or electro-chemically impact on the downstream flotation process.

“When you use steel media, for instance, it produces ferric ions, which tends to interfere with the chemistry of the particles and creates a passivating layer; this makes the particles hard to float or leach.”

“I don’t think people realise until they operate a plant without steel media just how important the chemical aspect is of downstream processing.”

“The consumption of ceramic media is much better than sand so you don’t need to have as much on hand.”

Another big advantage of ceramic media, especially in these days of escalating fuel costs, is power savings. These can range up to 20% compared with many sands.

“Using ceramic media is quite a cheap way of increasing your regrind capability. It also saves time with downstream processing by grinding to finer sizes and provides improvements in flotation and leaching afterwards.”
