Abstract

A METHOD FOR PREPARING CERAMIC MASSES, including the steps of mixing the components of dosing, grinding, and subsequent moistening of the obtained finely divided mixture, which are moistened to 1-6% in order to reduce the energy intensity of the process and increase the quality of the obtained products into a stream of gas energy carrier in which they are mixed and ground at a temperature of vaporization and a pressure less than atmospheric to form a mixture of terizuemoy size with zero residue on sieve 0,058-0,060 mm, and the resulting steam-gas mixture with the dispersed material are cooled to the dew point was followed vysl division of the gas flow and douvlazhn dissolved to 8-10% solid particulate material.

Description

and

00 SP

The invention relates to a technique for the production of building materials and can be used to obtain ceramic masses in the production of tiles.

The purpose of the invention is to reduce the energy intensity of the process and turn it on. the quality of the products.

In the drawing, a diagram of the implementation of the method of curing ceramic masses is given.

Slag, phosphoric production in the amount of 1.0 t / h dispenser 1 is fed to the crusher 2, crushed to a particle size characterized by a zero residue on the sieve, 3.0 mm and fed to the hopper 3. Water 60 is fed through the irrigator 4 into the same bunker 4 l / h (6% by weight of slag). The moistened putty is fed through the control dispenser 5 to the injection unit 6 of the gas-jet mill. Clay in the amount of 1 t / h through the dispenser 7 is fed to the crusher 8, where it is crushed to a particle size characterized by a zero residue on a 3.0 mm sieve and fed to the bunker 9. In the same bunker through the irrigator 10 the water is fed to 60 l / h. Clay control dispenser 11 is fed into the injector 12. Injectors 6 and 12 from a source of hot gas (not shown) is fed

a high-temperature energy carrier, which in the corresponding injector accelerates slag and clay and brings it to the grinding chamber, where, as a result of the collision of particles, their mixing and destruction occur. The grinding chamber maintains a pressure less than atmospheric and the temperature is equal to the vaporization temperature,

accelerating the destruction of particles. Lost velocity particles are carried to separator 14 where they are separated by size.

Undersized particles of the resulting mixture are returned to the injectors 6 and 12, and particles with a particle size characterized by a zero residue on

A sieve of 0.060 mm is transported to the dust precipitation device 15, where as a result of the expansion of the gas flow and its additional reflux, steam containing in it condenses and moistens the particles,

ensures their deposition without separation of the composition. The moistened particles are collected in a hopper 16, from where the feeder 17 is directed to

compaction, and the exhaust gas by the fan 18 is emitted into the atmosphere.
