Mechanical Operations Pick out the wrong statement pertaining to the roll crushers. Both the rolls run necessarily at the same speed Reduction ratio and differential roll speed affect production rate & energy consumed per unit of surface produced For hard material's crushing, the reduction ratio should not exceed 4 Maximum feed size determines the required roll diameter Both the rolls run necessarily at the same speed Reduction ratio and differential roll speed affect production rate & energy consumed per unit of surface produced For hard material's crushing, the reduction ratio should not exceed 4 Maximum feed size determines the required roll diameter ANSWER DOWNLOAD EXAMIANS APP
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 to form a particle of any size is proportional to the square 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 a particular size is proportional to the square root of the surface to volume ratio of the 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 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 ANSWER DOWNLOAD EXAMIANS APP
