Our advantages:
1). Excellent raw materials
2). Good customer service
3). Rapid delivery
4). Reasonable price
5). Production quickly
Experienced manufacture, we will be the best choice.
Alumina grinding media is mainly used in ceramic,glaze,paint,zirconia silicate,aluminum oxide,quartz,silicaon carbide,talc,lime carbonate,kaolin,titanium and other materials grinding and mechanical equipment accessories.
Advantages
1. high wear-resistance
The Alumina Balls` wear-resistance is higher than the common alumina balls`. When it is working, the ball won`t pollute the grinding materials, so it can keep the purity and improve the stability of grinded materials especially the ceramic glaze.
2. high density
The high density, high hardness and the high grinding characters save the grinding time, enlarge the smashing room. So it can improve the grinding efficiency.
3. Comparing with natural balls and stones, flint pebbles, France pebbles, our balls will help you save more costs: abridge milling and grinding time, improve the utilization of your ball mills, decrease the milling and grinding loss, and save electricity
4. Three kinds of high Alumina Grinding Balls and one kind of alumina lining available.
