Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.
The grinding media must be large enough to break up the largest particles fed to the mill and small enough to grind the material to the product fineness desired. As demonstrated by the experience of Century mine, an inappropriate media size choice can result in energy consumption double that of optimum operation.[ 8 ]

Grain size depends upon quantity of material to the ground required quality of surface finish; and hardness of workpiece material. Find and very fine grain size is used for precision grinding, however, coarse and medium grain size is used for rough grinding. Grade Grade of a grinding wheel is the indicative of hardness and tenacity of bond of
Step 2. Since the grinding was carried out in a wet overflow mill in closed circuit, the value of k should be taken as 350 ( Table 7.2 ). Substituting data into Equation (7.16), we get the replacement size of grinding balls as. d B = 25.4 6250 350 0.5 2.4 × 12.8 75 3.281 × 1.5 0.5 0.33 = 61 mm. Step 3.
