SU1240750A1 - Method of preparing ceramic slip - Google Patents

Description

The invention relates to the production of building materials, in particular to the manufacture of ceramic tiles during the preparation of puffer preparation of the masses, followed by dehydration in a spray dryer.

The purpose of the invention is to reduce the moisture content of the slip while simultaneously increasing its mobility and increasing the strength of the raw material.

Ceramic slip of the following composition, wt.%: Clay 61; kaolin 7; nepheline concentrate 30 and tiled combat 2, prepared using the following technology.

The melt, the scum, and 5–10% of the linear components, water and soda ash are loaded into a ball mill and ground to

The grinding of the slip with all the components is continued until the residue on the sieve 0063 1.5-2%. Next, the slurry is discharged into the pools, from where it is pumped to the spray dryer. The logs are pressed from the resulting press powder, which are then dried and fired.
