Product Description
Product Description
Ball mill hollow shaft
Weight: 5-30T
Applicable device: ball mil, cement machinery
Application: Cement, metallurgy, building material and others
Customizable: Yes
Hollow shaft is an important part of ball mill. Its function is bearing the rotary of ball mill shell. Technically, hollow shafts should not have below holes and sand holes on the neck of spherical tile and circular arc neck of shell connection. When producing, spherical tile needs grinding after part machining, to secure precision and smooth finish. This requires very high standard of casting technology.
Our main material for the Ball mill hollow shaft is similar to the followings:
