advantage：
1.it adopts shock chilling method，which not only improve the hardness of grinding balls; make grain refinement but also make the same hardness for inner and surface.it improves the grinding balls wear resistant propertyrty
2.efficiency is high;usage coast is low.get highly speak of from customers.fully use the iron water(average 75% above)、high production rate and longer life.
3.easy operation.if the spherical core is abrasion.change the spherical core ，then it will a new mould.save cost.
4.the grinding balls has good surface and no imperfection.it is the best choice to take the place of sand box mould.
