WhatsApp: +86 18838072829What is a ball mill trunnion bearing? Ball mill trunnion bearing, also called trunnion bearing housing, is an important component of the ball mill grinder, which mainly carries the weight and impact force of the whole ball mill cylinder.
WhatsApp: +86 18838072829Ball mill or trunnion bearings are widely used in wind turbine generators, communications satelites, the space shuttle, telescopes, bascual bridges, vaccum cleaners, firearms, vehicles, stage lighting instruments, and in many other areas as well. Whatever your need may be, BBR is capable and ready to manufacture to your specifications.
WhatsApp: +86 18838072829The components of the mill that rotate on bearings are the trunnions. The trunnion is a kind of cylindrical and tubular shaft with thick walls, wherein the ore passes through its inner diameter, both in the feed and in the mill discharge.
