Aluminum balls

Aluminum aluminum balls balls high quality raw materials, the use of advanced spray drying, dry-type automatic isostatic pressing process, sintered at high temperature tunnel kiln fuel, the products are widely used in ceramic glazes corporate grind , grinding the blank. Compared with natural stone balls, ordinary ceramic ball, wear resistance increased by 20 --- 40 times, the grinding efficiency is improved 40 - 60% 30 - 40% increase in mill efficiency, the overall cost is a natural stone ball 40- -60% of the life of the mill increase from two years to six - - 8 years. I choose plant wear aluminum balls as grinding media, with considerable comprehensive benefits.

And in isostatic aluminum grinding balls than natural pebbles, silicon carbide ball can increase milling efficiency. In speed, pellet, the proportion of water conditions, it can shorten the grinding time, increase single output, greatly reducing the cost of milling. Aluminum balls www.pxsbaixing.com/60.html
