However, the corresponding centrifugal force would multiply by a factor of 1.167 × 1.167, or 1.36. To take a more extreme example, consider the same wheel with a maximum safe operating speed of 6,600 rpm run on a 5-inch right angle grinder at 10,000 rpm. This represents an over-speed of about 1.5 times the wheel's designed speed.On the other hand, very low grinding wheel speeds, in the order of 3,000 to 4,000 fpm (about 15 to 20 m/sec) are needed for the surface grinding of various types of high alloy and high strength work materials, using the lower wheel speed as a means for minimizing the development of heat, to which certain types of materials and workpieces are ...

Berlioz studied the effect of particle load on grinding rate of a 7/9 mesh size fraction of natural, uncrushed dolomite in a 25.4 cm diameter laboratory ball mill (N: 0.6, J: 0.5, U: 0.2 to 1.6). Due to an unusually high initial rate of grinding, Berlioz defined sieve size interval 1 as 7/10 mesh instead of 7/9 mesh.Grinding bowl sizes 20, 45, 80 ml. Grinding ball diameter 0.1-20 mm.

8-3 Centrifugal force outward Fc mp& 2 Dm 2 (8.1) & is the angular velocity, mp is the mass of any particle (media or charge) in the mill and Dm is the diameter of the mill inside the liners. Gravitational force Fg mpg (8.2) The particle will remain against the wall if these two forces are in balance ie.a specified micron size. An empirical relationship shown in Table 1 is used to relate the overflow size distribution to the D50 C required to produce the specified separation. The relationship of this table is for typical or average grinding size distributions and may vary slightly depending upon the grinding characteristics of the ore itself.
