Manufacturing process for raw materials of tile ceramic plate

Abstract

The invention discloses a brick tile ceramic plate raw material manufacturing process, which comprises the following steps: selecting a variety of argil as a basic raw material, adding water, carrying out ball milling, carrying out filter pressing, carrying out diaphragm squeezing, carrying out back flushing, detecting a filter cake and crushing the filter cake, and is characterized in that the filter cake of the argil raw material is dehydrated through the mutual cooperation of the two processes of filter pressing and diaphragm squeezing. The dehydration device is used for dehydrating the pottery clay raw material, so that water in the pottery clay raw material is uniformly distributed, the lowest water content in the prepared pottery clay raw material is 16%, and the highest water content in the prepared pottery clay raw material is 20%. According to the manufacturing process of the brick-tile-ceramic plate raw material, multiple kinds of argil are selected as basic raw materials, water adding and ball milling are conducted, filter pressing, diaphragm squeezing, back flushing, filter cake detection and filter cake crushing are conducted, the situations of slurry explosion, core blackening and the like in the production process can be avoided, and the clay raw material with uniform moisture and good forming performance can be directly prepared; the subsequent extrusion forming procedure is facilitated, the production quality is ensured, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of tile and ceramic plate manufacturing, and in particular relates to a raw material manufacturing process for brick and tile ceramic plates. Background technique [0002] Bricks, tiles and terracotta panels are commonly used building materials. Manufacturers usually use extrusion molding methods for production, and extrusion molding requires clay raw materials to have the following properties: [0003] 1. Molding moisture is 16-20%; [0004] 2. The moisture of the raw material is relatively uniform, and the difference between the highest and lowest moisture in the interior is small; [0005] 3. The working pressure of extrusion is 1.8-3.5MPa, which has a certain strength. [0006] At present, clay raw materials are usually composed of a variety of clay, quartz, feldspar and other raw materials according to a certain ratio. There are two commonly used manufacturing processes for clay raw materials: [000...

AI Technical Summary

Problems solved by technology

[0007] The first is the traditional process of dry batching, which uses the methods of Raymond crushing, dry powder mixing powder mixing and color mixing, and stirring and granulation. High, low product quality, large dust during the transportation and use of dry raw materials and dry powder;

[0008] The second is ball milling wet batching, which is divided into spray tower process and filter press process. Among them, the hollow spherical particles produced by spray tower process have low strength and poor plasticity, which do not meet the requirements of extrusion molding technology used in brick, tile and ceramic plate industries. Although the filter press process can solve the problems of coarse raw material particles, high iron content in raw materials, and low product quality in the traditional dry material formulation method to a certain extent, it still has the problem of low moisture content in the ceramic filter cake. High, uneven moisture, the filter cake can not be directly used for extrusion molding, and frequent pulp explosion between filter cloth and filter plate, which cannot meet the actual production needs
