Mechanical Operations Rittinger's crushing law states that 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 Work required to form a particle of any size is proportional to the square 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 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 Work required to form a particle of any size is proportional to the square 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
