If slag grinding mill roller rotates poorly, the grinding capacity will decrease rapidly, which will influence granularity of finished product. So what factors can affect slag grinding mil roller rotation?

When slag mill rotates at high speed, the roller is mainly driven by suspension axis, while suspension axis is achieved by sliding bearing driven by electronic motor, so there is an intimate relationship between roller moving and sliding bearing on suspension bearing. If the roller rotates without flexibility, you should check whether the sliding bearing is normal. When dust falls on sliding bearing of suspension axis, the lubrication oil and dust will form greasy dirt without the good lubricating function. And the bearing friction will increase, which affect the flexibility of slag grinding mill.

For a further step, if the greasy oil is piled without instant removing, there will be a circumstance that sliding bearing and suspension axis will conflict together, stopping the roller rotating suddenly as well as machine stuff and burning electronic motor. Sometimes if sliding bearing lacks lubrication oil, the flexibility will also decrease. Except this, the worn roller will affect its rotating. When slag mill rotates, high hardness or large volume ore slag enters into roller and ring, which will generate caved piece, even enlarged roller and ring interval. And the roller is sometimes rotating, sometimes not, which can’t effectively grinding the slag and seriously influence the slag mill efficiency and output.
