Production system of porcelain tile

Abstract

The invention discloses a production system of a porcelain tile. The production system comprises a coal cinder preprocessing device for preprocessing coal cinder, a mixing device which is connected with the coal cinder preprocessing device and used for blending and mixing production raw materials of the porcelain tile, a forming device which is connected with the mixing device and used for pressing and molding the production raw materials after blending and mixing, and a sintering device which is connected with the forming device and used for sintering a pressed and molded green tile; the coal cinder preprocessing device comprises at least one magnetic separation device, a ball mill, a de-ironing device and a settlement tank which are sequentially arranged. The porcelain tile produced by the production system is high in whiteness and high in bending strength.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a production system of porcelain tiles. Background technique [0002] my country's construction industry has a huge demand for porcelain tiles. Most of the conventional porcelain tiles require sand-type barren raw materials, which are obtained from mountains. It is necessary to peel off the epidermal vegetation and the sticky loess on the surface of the mountain, which is harmful to the environment. The impact is huge, destroying national forests and causing soil erosion. [0003] On the other hand, the output of industrial cinder is very large. Although there are some ways of environmental protection and reuse, such as: adding to processed cement, making municipal bricks, etc., the amount of addition and use is small, which is far from being able to digest the amount of cinder produced every day. , and the added value of the product is low. [0004] At present, coal ...

Problems solved by technology

[0002] my country's construction industry has a huge demand for porcelain tiles. Most of the conventional porcelain tiles require sand-type barren raw materials, which are obtained from mountains. It is necessary to peel off the epidermal vegetation and the sticky loess on the surface of the mountain, which is harmful to the environment. Great impact, destroying national forests and causing soil erosion

[0003] On the other hand, the output of industrial cinder is very large. Although there are some ways of environmental protection and reuse, such as: adding to processed cement, making municipal bricks, etc., the amount of addition and use is small, which is far from being able to digest the amount of cinder produced every day. , and the added value of the product is low

[0004] At present, coal cinders are also used as raw materials for porcelain tiles, but the quality of the products is low. The routine quality inspection items of porcelain tile products: whiteness, flexural strength, water absorption and other aspects of performance are not up to the existing products. Indicator requirements

Moreover, the amount of coal slag used is less, and the recycling rate of coal slag is not high

[0005] In terms of cinder treatment: in the prior art, cinder and other mud and sand materials are added to the ball mill, and the iron is removed after ball milling into a slurry. Because the slurry contains mud, the slurry has poor fluidity and high viscosity, so the iron removal is not complete. , resulting in very low whiteness of the finished product, and due to the presence of mud, the efficiency of the ball mill is low and consumes more electricity

Furthermore, the existing cinder generally has a high calcium content (about 5-6%) and is difficult to sinter. After firing, the porosity of the finished brick is high, which leads to a relatively high water absorption rate of the fired product ( The water absorption rate is about 0.5%), and the flexural strength is relatively low (the flexural strength is only about 1400N)
