Processing method and device for improving plasticity of ceramic raw materials

Abstract

The invention relates to a processing method and method for improving plasticity of ceramic raw materials. The processing method comprises the following steps of: placing ceramic ore raw materials in a silica conical container, uniformly striking the materials for 4-6 hours by adopting a cone body of a casting steel head so as to change round granular ceramic raw materials into a triangular mineral structure, placing the struck raw materials in mud so as to stale, stir and separate, delivering the light petuntse suspended to the upper part of the silica conical container to a press fit through a machine, and carrying out ball-milling after dehydration on the light petuntse, so as to change grain fineness. The processing method and the device of provided by the invention have the advantages that the plasticity index is improved by 50%, the drying intensity is improved by 40%-50%, thus, the using grade of general plasticity ceramic clay is improved, the first-pass yield of ceramic finished products is improved by 10%-20%, and the intensity of the products is improved.

Description

technical field [0001] The invention relates to a processing method and device for improving the plasticity of ceramic raw materials. Background technique [0002] Daily-use ceramic raw materials are divided into three categories: plastic clay raw materials, non-plastic quartz raw materials (barren raw materials) and flux raw materials. Clay raw materials are one of the main raw materials for daily ceramic materials. The amount of clay raw materials used in fine porcelain ingredients often reaches 40-60%, and the amount used in pottery and stoneware can also be increased. The reason why clay is used as the main raw material for ceramic products is due to its plasticity and sinterability. The mineral components of plastic raw materials mainly refer to clay minerals, which are all layered silicates, whose particles are generally below the microscopic size (10<um), and have certain plasticity. Such as kaolin, bentonite, halloysite, china clay, etc. Plastic raw materials...

AI Technical Summary

Problems solved by technology

[0003] Ceramic raw materials are processed from ore raw materials into ceramic blanks. Generally speaking, the plasticity index is 3-5Pa. The usual method is to use wet ball milling to pulverize coarse-grained ceramic raw materials to achieve the fineness required by the product, but the problem cannot be solved after the fineness meets the requirements. plasticity

In this way, general coarse ore ceramic raw materials cannot be used as ceramic raw materials to waste resources, and at the same time, the plasticity index, dry strength, and product strength cannot reach the ideal level.
