Description

Technical Field

[0001] The invention belongs to the technical field of building ceramic production, and in particular relates to a building ceramic wet powder making and wet production system. Background Art

[0002] At present, the wet powder making in my country's building ceramics industry has energy-saving and environmental protection problems such as high energy consumption, high pollution and high emissions, while the existing ceramic dry powder making technology has difficult-to-overcome technical bottlenecks in powder making and has been rarely used in the industry. Although the ceramic industry has made some achievements in the development and application of coal powder direct combustion and mud heating energy-saving technologies in raw material powder making, the energy saving range is still limited.

[0003] At present, the difference between dry powder making and wet powder making of building ceramics is the grinding process of raw materials. Dry powder making is to obtain dry powder particles through vertical mill grinding. Dry powder particles can also be obtained by improving some links of wet powder making through mud filtration, drying and powder breaking. The core problem of granulation and powder making process can be improved by upgrading to meet the production process requirements of products. The difficulties of dry powder making and wet powder making for ceramic production appear in the powder particles. Wet powder particles meet the requirements of later pressing, drying and firing processes through aging modification. The pressing, drying and firing problems caused by the solid, difficult to drain and easy to pulverize characteristics of dry powder particles are difficult to effectively solve and break through with the existing dry powder making process technology. Due to different process flows, the gas energy consumption, electricity consumption and water consumption of wet powder making are higher than those of dry powder making. Because of its mature process, the powder material meets the needs of press forming and pulverization after aging and is widely used. Dry milling is prone to cracks during the production process, causing defects and damage to the brick surface, and cannot achieve the same production effect as wet milling, making dry milling unable to be universally implemented.

[0004] Whether the two powder making methods can meet the production requirements is determined by the granulation effect of the powder particles. In dry powder making, the granulation effect of wet powder making is mainly affected by the wet production system. Summary of the invention
