Delivery status2.5 The measurements of products can vary between different formats, thicknesses range from 3 mm (for ultra-thin tiles) to 30 mm (for thickened tiles).The required composition of raw materials, including also recycled wastes, is mixed and ground in mills, either in a wet or a dry process. In the wet process, the slurry produced (with around 25-30 % water) is treated in spray driers that use thermal energy from natural gas and high air pressure in order to produce a dry powder with spherical granules of appropriate size distribution, ready to be pressed. In the drying process the production of energy via cogeneration is a widespread practice. In the dry process, without water, no spray driers are used.
