Problems solved by technology

[0002] Porcelain clay is the raw material used to make porcelain. The quality of porcelain clay directly affects the quality of porcelain. At present, the process of producing porcelain clay in the market is mainly to put the raw materials into the ball mill according to the proportion and grind them to refine them, and then sieve them. The use of this process to produce high-quality daily-use porcelain clay puts forward certain requirements for each raw material. Therefore, raw materials with poor quality cannot be used.

preparation example Construction

[0017] The preparation method of excellent daily-use porcelain clay of the present invention comprises the following steps:

[0018] Step 1: The kaolin ore, porcelain stone powder, talc, bentonite, and fine sand are refined to 325 mesh by ball milling, and then sieved to remove impurities to obtain 325 concentrate for magnetic separation treatment; ball mill model TCM1180-3T, motor power: 22kw , the concentration of the ball mill slurry is controlled at 40-50%. After 20 hours of ball milling, the ball mill is diluted with water to 10-30%, and then the YZS-800 circular vibrating screen (motor power 0.55kw) is used to screen and remove impurities. The model of the magnetic separator is YCG-Ⅱ-A08 permanent magnetic separator.

[0019] Step 2: Slurry the kaolin concentrate and Hunan mud through a mixer and magnetically separate them for standby. The model of the magnetic separator is YCG-Ⅱ-A08 permanent magnet magnetic separator. Kaolin concentrate is obtained from raw kaolin ore...

[0022] Example 1: Raw materials such as kaolin ore, porcelain stone powder, talc, bentonite, and fine sand are refined to 325 mesh by ball milling, and then sieved and removed by magnetic separation for standby; Hunan mud and kaolin concentrate are processed by magnetic separation after pulping Standby; according to the dry ratio of kaolin raw ore 5%, porcelain stone powder 40%, talc: 2.5%, bentonite 2.5%, fine sand 10%, Hunan mud 20% and kaolin concentrate 20%, the slurry is mixed and passed through The filter press filters the mud with a water content of 26%. The firing whiteness of the mud is 76.05 (greater than 70), which meets the national standard GB / T3532-2009 standard for high-quality daily-use ceramics. The fired sample has no defects such as spots, stable shrinkage and no deformation, and can meet the requirements of high-quality daily-use ceramics. Production needs.

Abstract

The invention provides a formula of superior daily porcelain clay. The formula comprises the following components in percentage by weight: 0-50% of kaolin raw ore, 20-60% of porcelain stone powder, 0-3% of talc, 0-3% of bentonite, 0-10% of fine sand, 0-30% of Hunan mud and 10-40% of kaolin concentrate. According to the invention, the porcelain stone powder, talc, bentonite, fine sand and kaolin raw ore are subjected to ball milling, refining, screening, impurity removal and magnetic separation respectively, then the mixture, kaolin concentrate and Hunan mud are subjected to slurry preparationand filter pressing according to the proportion to prepare the domestic ceramic pug. The firing whiteness of the domestic ceramic pug is larger than 70, and the domestic ceramic pug meets the standardof national standard GB / T 3532-2009 superior domestic ceramics. The fired sample has no defects such as spots, is stable in shrinkage and free of deformation, and can meet the production requirementsof superior daily porcelain.

Description

technical field [0001] The invention relates to the field of processing non-metallic ores, in particular to an excellent daily-use porcelain clay and a preparation method thereof. Background technique [0002] Porcelain clay is the raw material used to make porcelain. The quality of porcelain clay directly affects the quality of porcelain. At present, the process of producing porcelain clay in the market is mainly to put the raw materials into the ball mill according to the proportion and grind them to refine them, and then sieve them. Separation and removal of impurities, the use of this process to produce high-quality daily-use porcelain clay puts forward certain requirements for each raw material, so raw materials with poor quality cannot be used. Due to a large number of developments in recent years, the high-quality resources of non-metallic minerals in my country have been greatly reduced, and the number of poor-quality mineral resources is relatively large. If these l...
