In the ceramic industry, which is one of the sectors with a high raw material usage rate, raw materials such as clay, quartz, and feldspar are used at high rates. Recycling activities and the recovery of these resources are a great necessity both economically and environmentally. In the sanitary ware and ceramic tile industries, it is possible to recycle the wastes that occur as a result of both usage and production errors. In order to ensure recycling, the waste should be reduced to a fine size by crushing and grinding processes. Due to the high strength of the baked products, a high amount of energy is consumed in the grinding process. For this reason, it is very important that the size reduction processes are carried out under optimum conditions. Waste material reduced to a fine size should be added to the ceramic recipe in appropriate proportions. These additions should be made in proportions that will not greatly affect the product properties. In this study, grinding operations were carried out in different size groups and at different times to investigate the most suitable conditions for grinding operations and to examine the crushing behavior of the waste. Additionally, the effect of the waste material added to the production recipe at different rates on the product was examined.
