centrifugal force in vertical mill
Centrifugal Force
Centrifugal force is the apparent outward force on a mass when it is rotated. Since Earth rotates around a fixed axis, the direction of centrifugal force is always outward away from the axis, opposite to the direction of gravity at the equator; at Earth's poles it is zero. (Centripetal force is the necessary inward force that keeps the mass from moving in a …

Centrifugal Force- Definition, Principle, Examples (vs Centripetal force)
Centrifugal force is an outward fictitious force that is experienced by an object moving in a circular path directed away from the center of rotation. The direction of this force is away from the axis of rotation and is parallel to the axis of rotation. Centrifugal force is equal in magnitude and dimensions with another force (centripetal) that ...

How to choose between ball mill and vertical roller mill?
4. Grinding process. In the ball mill, the material is mainly crushed by impact and friction. In the vertical grinding mill, the material is mainly extrusion, and grinding is the auxiliary. The residence time of the material in the vertical mill is 2-3 minutes, while in the ball mill it takes 15-20 minutes.

Centripetal vs Centrifugal Force: What's the Difference
The only force causing an object's circular motion is centripetal force, which is always directed toward the center of the circular path. If a car is rounding a bend, for example, the centripetal force making it move in a curve rather than a straight line is directed along the radius of the circle the car is tracing out.
