In grinding, selecting calculate the correct or optimum ball size that allows for the best and optimumideal 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.

The characteristics that enable us to distinguish one substance from another are called properties. a physical property is a characteristic of matter that is not associated with a change in its chemical composition. familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
As you will be able to see in the data below speeds cover a large range of values. historically machinists have thought that obtaining data for grinding was simply a matter running tests on a given metal, collecting the data, and producing tables with the best feeds and speeds. however efforts to do just that found the subject was far more complex.
Total solids content dry matter dm reading time 5 minutes. the total solids content includes both the suspended solids and dissolved salts. the total solids content is also used to determine a sludge dry weight expressed as a . dry solids content at 105176c.
Formulating a ration is a matter of combining feeds to make a ration that will be eaten in the amount needed to supply the daily nutrient requirements of the animal.in addition to being nutritionally adequate, a good cattle ration should be economical, palatable and free of toxic substances. efficiency is increased when rations are consumed at a level to supply a larger amount of energy in ...

All properties of matter are either extensive or intensive and either physical or chemical. extensive properties, such as mass and volume, depend on the amount of matter that is being measured. intensive properties, such as density and color, do not depend on the amount of matter.
Physical properties used to describe matter can be classified as 1 extensive depends on the . amount. of matter in the sample e.g. mass, volume, length . 2 intensive depends on the . type. of matter, not the amount present
