Mechanical Operations The constants (Kb, Kr and Kk) used in the laws of crushing (i.e., Bond's law, Rittinger's law and Kick's law) depend upon the Neither A nor B Type of crushing machine Both A & B Feed material Neither A nor B Type of crushing machine Both A & B Feed material ANSWER DOWNLOAD EXAMIANS APP
Mechanical Operations Rittinger's crushing law states that For a given machine and feed, crushing efficiency is dependent on the size of the feed & product Work required to form a particle of any size is proportional to the square of the surface to volume ratio of the product Work required to form a particle of a particular size is proportional to the square root of the surface to volume ratio of the product Work required in crushing is proportional to the new surface created For a given machine and feed, crushing efficiency is dependent on the size of the feed & product Work required to form a particle of any size is proportional to the square of the surface to volume ratio of the product Work required to form a particle of a particular size is proportional to the square root of the surface to volume ratio of the product Work required in crushing is proportional to the new surface created ANSWER DOWNLOAD EXAMIANS APP
