Mechanical Operations Rittinger's crushing law states that Work required in crushing is proportional to the new surface created 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 For a given machine and feed, crushing efficiency is dependent on the size of the feed & product Work required in crushing is proportional to the new surface created 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 For a given machine and feed, crushing efficiency is dependent on the size of the feed & product ANSWER DOWNLOAD EXAMIANS APP
