Summary:Ceramic is an engineering material that has endeared itself to many sectors especially the building services sector where it is used for floor tiles. Machining is a necessary finishing operation after casting and other forming operations. A very important machining operation performed on ceramic materials such as tiles is grinding to pave way for easy installation, aesthetics and safety. This work investigates the elemental and chemical composition of the raw materials used in the production of the ceramic tiles under investigation and study the effect of different grinding procedures on some mechanical properties of the ceramic tiles. The tiles were ground at two different grinding speeds and two different levels (continuous and intermittent at 2 seconds intervals). Breaking strength, flexural strength, hardness, and surface roughness before and after grinding were analyzed using the Signalto-Noise (S/N) ratio. The result revealed that the elements and their respective oxides present in the raw materials were able to give strength, rigidity and support to the ceramic article. Also, grinding was found to affect the mechanical properties of the ceramic tile samples as the breaking strength and flexural strength reduces from 339.77 N for the control sample to as low as 273.30 N and 16.40 N/mm2 respectively.
