Method for irregular ceramic tile forming

Abstract

The invention relates to a method for irregular ceramic tile forming. The method for irregular ceramic tile forming is characterized by comprises the first step of conducting ball milling on the raw material into mud with water content being 33%-40%; the second step of conducting filtering pressing on the mud obtained in the first step through a pressure filter to make the water in a filter cake reach 15%-18%; the third step of extruding the filter cake obtained in the second step through a vacuum extruder into a platelike green body; the fourth step of conducting flower pattern coining and cutting on the platelike green body through a roller cutting mold to obtain an irregular green brick blank; the fifth step of stoving the irregular green brick blank. Compared with the prior art, the method for irregular ceramic tile forming has the advantages of being environmentally friendly, low in cost, and high in production efficiency, and simple in technology aimed at the production of the irregular tile.

Description

technical field [0001] The invention relates to the technical field of tile production and processing, in particular to a method for forming special-shaped tiles. Background technique [0002] The traditional ceramic tile molding method is generally to first ball-mill the raw materials into a slurry with a moisture content of 33%-40%, then sieve, granulate and make powder through a spray tower, and then press the powder with a moisture content of 5%-9% into a hydraulic press mold. After drying. There are several problems in the production of ceramic tiles in this way: ① granulation by spray drying, so that the moisture content of the particles is between 6% and 7%, and more dust and sulfur-containing waste gas will be generated during the production and processing process. On the one hand, it affects the environment in the working area, causing environmental pollution and is not environmentally friendly. On the other hand, the spray drying method consumes more energy, which...

Problems solved by technology

There are several problems in the production of ceramic tiles in this way: ① granulation by spray drying, so that the moisture content of the particles is between 6% and 7%, and more dust and sulfur-containing waste gas will be generated during the production and processing process. On the one hand, it affects the environment in the working area, causing environmental pollution and is not environmentally friendly. On the other hand, the spray drying method consumes more energy, which is high in energy consumption and high in cost; This process has high requirements on the material and other aspects of the mold, and for pressing tiles of different shapes, a variety of molds are required, especially for the production of special-shaped tiles. Because of the variety of shapes, a large number of molds are required for production. As a result, the defects of complex process, low production efficiency and high production cost
