· For that there is a speed factor called ndm that can be calculated. Take the mean diameter of the bearing in mm (bore in mm + outside in mm divide by 2) and multiply this by the speed the bearing will operate at. Normal motor type appliions operate well below ndm = 500,000. Above ndm = 500,000 indies high speed.
· Practical 1: Title: Ball Milling Objective: To grind the coarse salt to a smaller size by using a ball mill and to obtain the particle size distribution of the initial and the sieved final mixture. Introduction: 'Ball milling is a method used to break down the solids to smaller sizes or into a powder. A.
