Alumina balls:
production technology:
advanced spray drying granulation, dry type full automatic iso-static pressure process and high temperature roller kiln sintering technology.
Features:
high hardness, high density, high strength, good toughness and same structure inside and outside.
Usage:
With its high efficiency and low wear lost, it is particularly fit for architectural pottery and fine chemcial industry for ball-milling glaze and raw materials. It can greatly improve production efficiency without adding ball mill equipments and other infrastruction facilities.
