Medium alumina grinding ball D30mm, D40mm, D50mm, D60mm
Medium alumina grinding ball produced by isostatic machines and sintered in high temperature tunnel kiln. Its wear resistance is increased 20-40times and its grinding efficiency is increased 40-60% compared with natural stone ball and normal ceramic balls. Except that using medium alumina grinding ball will increase the working life of mill.
Our balls made strictly according to international starndard and receive welcome by many end users.It is durable ,efficient and fast delviery.
Characteristics of alumina grinding ball from us:
High density---2.7-3.0
High hardness----7
High temperature resistance
High pressure ability---50mpa
Anti-alkali and sulfur corrosion---tested and approved by many chemical factories
High alumina grinding balls D0.8-25 are available, alumina content 92%, 95%, 99%,which are durable, competive price and timely delivery.
