In a ball mill, the power consumption is varied according to the shifting of the centre of gravity in the internal volume of the mill.when the mill is empty, the fraction of volume occupied by the grinding media is more. but when the mill is filled with some feed, as the centre of gravity of grinding media shifts up,the fraction of volume occupied by the grinding media decreases. so power consumption is less.
- Power =0.285*d(1.073-j)m*n
d - internal diameter of mill
j - fraction of mill volume occupied by media
m - mass of grinding media in tonnes
n - number of rotations of the mill

What is a soccer ball filled with?
A soccer ball is typically filled with air. The amount of air and pressure inside the ball can affect its bounce, weight, and overall performance on the field. Overinflating or underinflating the ball can impact a player's ability to control and maneuver it during gameplay.
Are soccer ball's filled with helium?
no
The hollow , fluid-filled ball of cells that develops from the morula is the?
the morula develops into a hollow, fluid-filled ball of cells called a blastocyst.
Will the helium soccer ball bounce higher than a soccer ball filled with air?
A helium-filled soccer ball will not bounce higher than a soccer ball filled with air. While helium is lighter than air, the elasticity and structural integrity of the ball's material are more crucial for how high it bounces. A soccer ball filled with air is typically more pressurized and better able to maintain its shape, leading to a higher bounce. Therefore, the air-filled soccer ball is likely to perform better in terms of bounce height.
What's that big ball that rolls across an empty abandoned room called?
A wrecking ball.
What was a golf ball filled with before 1850?
chalk
Is a rugby ball hollow?
Yes, and filled with air.
Where is a ball bearing on a car?
In the compass held inside a plastic ball filled with liquid on the dashboard:)
How can the density of a hollow lead ball filled with water be increased?
The density of a hollow lead ball filled with water can be increased by adding a denser material, such as mercury, into the ball. This will increase the overall mass of the ball without significantly increasing its volume, thus increasing its density.
What is a birthing ball?
A birthing ball is an air-filled rubber ball which provides a soft sitting surface for a woman who is undergoing labour.
What is a ball pit?
A ball pit is a play area intended for children, filled with colourful plastic balls.
While in empty space an astronaut throws a ball at a velocity of 14 ms. What will the velocity of the ball be after it has traveled 2 meters?
The velocity of the ball will remain constant at 14 m/s since there are no external forces acting on it to change its velocity in empty space.
