• # prt 140: lesson 6 flow measurement – mining mill operator

Density = mass/volume = M/V. Volumetric flow = volume/time = V/T. Volumetric flow x Density = (V/T) x (M/V) = M/T. Density varies with temperature, so you need to know the exact density at the flowing temperature to calculate mass. Balance and convert all units as needed

• ### calculate and select ball mill ball size for optimum grinding

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and

• ### ball mill critical speed

A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical

• ### ball mills - an overview | sciencedirect topics

Generally, filling the mill by balls must not exceed 30%–35% of its volume. The productivity of ball mills depends on the drum diameter and the relation of ∫ drum diameter and length. The optimum ratio between length L and diameter D, L: D, is usually accepted in the range 1.56–1.64

• ### how to calculate ball mill volume ball mill- machinery

Ball Millchargevolumecalculation Sourena. Calculation of ball mill charge volume mtm calculation of ball mill charge volume we can calculate the steel charge volume of a ball or rod mill and express it as the of the volume within the liners that is filled with grinding media while the mill is stopped the charge volume can be gotten by measuring the diameter inside the liners and the distance

• ### volume calculator

Given James' golf ball has a radius of 1.68 inches, and the height of the spherical cap that Jack cut off is 0.3 inches, the volume can be calculated as follows: volume = 1/3 × π × 0.3 2 (3 × 1.68 - 0.3) = 0.447 in 3

• ### how to accurately measure the diameter of a ball

Jun 02, 2019 · If you’re also interested in calculating the volume of a three dimensional sphere such as a ball, you can also use the following equation to figure out the volume of your ball. V = r. In this equation, V = volume and r = the radius of your ball or sphere. Firstly you’ll need to find out the radius of your sphere

• ### ball mill design/power calculation

Dec 12, 2016 · Ball Mill Power Calculation Example. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350

• ### ball mill- an overview | sciencedirect topics

The minimal magnitude of ball size is calculated in millimeters from the equation: where db.max is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3 ); D is inner diameter of the mill body (m)

• ### volume calculator|calculate ball, cone, cube

The measure of space that an object or material occupies is called as volume. It is commonly measured in gallons, liters, or milliliters. This volume calculator used to calculate the various simple shapes of volume such as cone, cube, ball, cylinder and rectangular tank using the known values

• ### 6 ways tocalculate volume-wikihow

Dec 10, 2020 · To calculate the volume of a cylinder, you must know its height and the radius of the circular base (the distance from the center of the circle to its edge) at the top and bottom. The formula is V = πr 2 h, where V is the Volume, r is the radius of the circular base, h …

• ### examples of ways tomeasure volume

With sound, its volume is the loudness of the sound. With a container, its volume would be its capacity, or how much it can hold. Volume is often expressed in cubic units determined by the International System of Units. Learn how to measure volume with ease

• ### 3 waysto measure a fitness ball-wikihow

Oct 08, 2020 · Measure the height of your fitness ball against a wall. Alternatively, you can use your ball’s height to determine whether it’s inflated correctly. Use painter’s tape and make a mark on your wall at the same height as the fitness ball’s diameter. Then, inflate your fitness ball until it’s level with this mark

• ### how to measure flour correctlyby weight andvolume

Oct 04, 2018 · You do you! There are still ways to make sure measuring by weight is done as accurately as possible. There are two ways to measure by volume: The “scoop and sweep” method; The “spoon and level” method; If you see an online recipe that only lists the ounce or gram measurements, ask the author if they can recommend one method over the other
