Alumina cylinder for cement 　　Al₂O₃(%):92 　　Size/mm:15*16 　　Bulk density(g/cm³):3.65 FEATURES 　　Alumina cylinder is specially used for cement factories,it has the advantages of lower ware lose,superior hardness,high density Laboratory and industrial tests have proved that our super alumina ball SNQ with higher grinding efficiency compared with normal alumina ball,steel ball and steel cylinders. APPLICATION 　　SNQ with Lower wear-loss prolong the service life,reducing the production cost while normally balls has higher wear loss and fragile to broken during industrial production. 　　SNQ helps cement factories save a lot of production cost,reducing the energy costs Compared with steel ball and steel cylinders. 　　Vanna SNQ is the most economical and environmental protection new materials specialized for cement factories.
