how does the volume change after crushing aggregate

the soil when its aggregate size distribution (mass fractions across different size classes) shifts or transfers from wo to ~~(~ to i-l) after one crushing stage (tillage pass). P, often called a transition matrix, maintains the properties of a Markov chain and does not change with the number of tillage passes performed but depends . Get Price

volume change crushing stone into aggregate, bulking factor

Bulking of Fine Aggregate The volume increase of fine Aggregate due to the presence of moisture content is known as bulking This is due to the fact that moisture causes a film of water around sand particles which results in the increase of volume of sand, for moisture content of about 5 to 8%, this increase of volume may be a much as 20 to 40%, depending upon the grading of sand
