Sanitary ceramic slip ball-milling process

Abstract

The invention discloses a sanitary ceramic slip ball-milling process. The sanitary ceramic slip ball-milling process comprises the steps that raw materials including, by weight, 900-1350 parts of a hard material, 600-950 parts of a soft material, 540-860 parts of water, 25-45 parts of water glass and 3-12 parts of sodium carbonate are weighed, and the materials are divided into primary entry milling materials and secondary entry milling materials, wherein 900-1350 parts of the hard material, 360-600 parts of the water, 150-300 parts of clay, 15-30 parts of the water glass and 3-12 parts of the sodium carbonate compose the primary entry milling materials, and the remaining parts, other than the primary entry milling materials, in the weighed raw materials compose the secondary entry milling materials; ball milling of the first time is conducted, wherein ball-milling elements and the primary entry milling materials are put into a ball mill, and ball milling is conducted for 6-9 hours, so that primary slip is obtained; and ball milling of the second time is conducted, wherein one third of the primary slip and the secondary entry milling materials are subjected to ball milling together for 30-50 minutes, so that secondary slip is obtained. By means of the process, energy consumption can be remarkably lowered, production efficiency can be improved, and the qualification rate of finished products can be increased.

Description

technical field [0001] The invention relates to the field of sanitary ceramics, in particular to a ball milling process of sanitary ceramic mud. Background technique [0002] The existing sanitary ceramic slurry is made by weighing hard materials (such as feldspar, quartz, etc.) and soft materials (such as kaolin, washed china clay, etc.) according to the formula, and putting them into the grinding equipment together through a ball mill; The ball milling method has the following disadvantages: First: The raw materials in the formula have very different grinding properties. Since the particle size of soft materials such as clay is very small, they can disperse by themselves during processing. There is no need to go through repeated grinding for a long time, while hard materials need several times or even longer grinding time to achieve the required fineness; second, when soft and hard materials are ball milled together, due to the large amount of soft materials and the High ...

[0002] The existing sanitary ceramic slurry is made by weighing hard materials (such as feldspar, quartz, etc.) and soft materials (such as kaolin, washed china clay, etc.) according to the formula, and putting them into the grinding equipment together through a ball mill; The ball milling method has the following disadvantages: First: The raw materials in the formula have very different grinding properties. Since the particle size of soft materials such as clay is very small, they can disperse by themselves during processing. There is no need to go through repeated grinding for a long time, while hard materials need several times or even longer grinding time to achieve the required fineness; second, when soft and hard materials are ball milled together, due to the large amount of soft materials and the High viscosity will wrap the hard material, resulting in a smoother shape of the hard material, which greatly reduces the processing efficiency of the grinding process of the hard material; third, long-term ball milling will also destroy the particle structure of the soft material , thereby reducing the pass rate of semi-finished products and finished products; in summary, the way of one-time ball milling consumes a lot of processing time and electric energy, greatly reduces production efficiency, and reduces the pass rate of semi-finished products and finished products
