The vibration in grinding machine is measured by vibrometer. Vibrometer is the one of the instruments for measuring vibration. The components of vibrometer are sensor, contact pin, Rubber cap, magnetic holder and display screen. The size of the machine is very small. It is portable and we can use it on any machines.

adopted for the fabrication of the machine. Dry clay-free sand sample was tested with the machine for operational effectiveness and particle size distribution. The result shows that the machine is suitable for sieving sand grain size of the order of 0.1 to 1.0mm but cannot sieve larger particles such as gravel.

GRINDING MACHINES. TC 9-524 Chapter 5. GRINDING MACHINES. Grinding is the process of removing metal by the application of abrasives which are bonded to form a rotating wheel. When the moving abrasive particles contact the workpiece, they act as tiny cutting tools, each particle cutting a tiny chip from the workpiece.
