The performance of a stud grinding machine is done with particles size discretization analysis with sieve to validate its preference for bone dried or roasted materials. The discretization analysis is done by grinding five samples of 2kg roasted guinea corn at different speeds - 600,900,1200,1500 and 1800 rpm using a variable speed 2Hp electric motor under 1:1 speed ration respectively. The products resulted were discretized into particle sizes with a vertical throw electromagnetic vibrating sieve and the grinding efficiency is a function of speed. The particles generated as x-rayed by the results of vibrating sieve which has seven sets of sieves 10,15,20,25,30,35,and 40 with a collector that collects particles less than 40 from the set of the speeds reveals that as the speed increases the finer (smaller) the particle size and particles whose sizes are lesser than 40 were obtained to suggest that higher speed favours the grinding efficiency of a stud grinder.
