EFFECT OF WASTE ADDITION ON PLASTICITY OF MIXTURES: Wall tiles are formed using the dry pressing technique using as much as seven percent water to impart plasticity to the raw mix.
In the manufacturing of ceramic tiles by dry pressing method on the flow-conveyor lines by single-firing, the main criterion of obtaining a product of reduced thickness is to increase their mechanical strength in the molded, air-drying and in fired state that connected with the need to provide them with sufficient mechanical strength to be able to make further technological operations--transportation of semi-finished products for the roller conveyor in drying unit, its engobing, glazing and firing without deformation and fracture.
