Embodiment 1

[0022] Each raw material and its weight percentage are as follows:

[0023] Black mud: 18%

[0024] Tang county soil: 5%

[0025] Cooked: 5%

[0026] Feldspar: 32%

[0027] Porcelain Stone: 35%

[0028] Talc 2%

[0029] High alumina sand: 3%

[0030] Among the above raw materials, the black mud is a soft material, and the others are hard materials.

[0031] Specific steps:

[0032] 1) According to the above ratio, put the black mud and water into the ball mill in a ratio of 6:4, then run the ball mill, grind it until the fineness reaches 325 mesh, and sieve the remaining 1% mud. Depending on the local water quality, an appropriate water reducer should be added during grinding to ensure that the mud has better fluidity.

[0033] 2) Grind the feldspar into 325 mesh with a vertical mill, sieve the remaining 3% fine powder, and put it into the silo for use.

[0052] Pyrophyllite 8%

[0053] Manzu Stone 4%

[0054] Cooked 6%

[0055] Talc 1%

[0056] Among the above raw materials, the black mud is a soft material, and the others are hard materials.

[0057] Specific steps:

[0058] 1) According to the above ratio, put the black mud and water into the ball mill at a ratio of 5:3, then run the ball mill, grind it until the fineness reaches 370 mesh, and sieve the remaining 2% mud. Depending on the local water quality, an appropriate water reducer should be added during grinding to ensure that the mud has better fluidity.

[0059] 2) Grind the feldspar into 300 mesh with a vertical mill, sieve the remaining 4% fine powder, and put it into the silo for use.

[0060] 3) Grind the porcelain stone i...

Abstract

The invention relates to an energy-saving dry powder production method for building ceramics. The method is characterized in that the method includes the following steps: (1) hard materials and soft material in a green body formula are separated; (2) a ball mill is used for processing the soft material with high moisture content into slurry with 40 to 70 percent of moisture content for later use; (3) a pulverizer is used for respectively processing the hard materials into fine powders meeting requirement and conveying the fine powders into respective bins; (4) according to the green body formula, an automated batching system is used for mixing the processed fine hard material powders in batches according to proportion; and the prepared slurry as humidizer and the mixed fine hard material powders are forcibly mixed and granulated in a mixing granulator; (5) after granulation, granules are screened and optimized, and are then dried into the needed granular powder in a fluidized-bed dryer, and the granular powder can be used after being aged for 24 hours. The invention has the advantages of energy saving, consumption reduction and little pollution.

Description

technical field [0001] The invention specifically relates to an energy-saving dry powder making process for architectural ceramics. Background technique [0002] Existing building ceramics, especially the automatic production line of ceramic wall and floor tiles, as long as the manufacturer uses a large-tonnage press to press and form, the powder used is prepared by a wet process. That is, after the raw materials enter the factory, weigh various raw materials and send them to the ball mill. At the same time, add 30% to 40% of water, and then grind for 10 to 18 hours. After reaching the required fineness, put it into the mud tank, and then spray and granulate through the spray drying tower, and finally make the required powder. [0003] There are two main aspects of this process: large energy consumption and waste. One is that the ball mill wastes electricity. Because of the several raw materials in the green body formula, their grinding properties are very different. The ...
