Problems solved by technology

However, due to the high price of natural gas and the shortage of gas supply in winter
All the manufacturers that carry out "coal-to-gas" only changed their kilns, and the pulverization process of spray towers still uses coal as fuel in the ceramic industry, which has not fundamentally and completely achieved the country's "coal-to-gas" atmospheric governance and requirements for energy saving and emission reduction

Abstract

The invention relates to a large-sized porcelain glazed tile dry powder manufacturing process, and belongs to the field of architectural ceramics. The large-sized porcelain glazed tile dry powder manufacturing process comprises the following steps: material selection, raw ore crushing, batching, mixing, vertical milling and fine grinding, fine powder collection and storage, floatation granulation,sulfuration drying, powder sieving, iron removal, powder storage and obsolescence, compact forming, green body drying, glazing, ink jetting (surface decoration), firing, cooling, polishing trimming,super clean anti-fouling treatment, inspection, sorting, packaging and warehousing. According to the invention, dry powder manufacturing is applied to replace original wet powder manufacturing, so that energy can be effectively saved, emission can be effectively reduced, meanwhile, environmental pollution can also be avoided, and product quality is stabilized.

Description

technical field [0001] The invention relates to a dry-process powder-making process for large-scale porcelain glazed tiles, which belongs to the field of architectural ceramics. Background technique [0002] Recently, architectural ceramic product series can be divided into interior wall tiles, exterior wall tiles and floor tiles according to their uses. Among them, floor tiles can be subdivided into: polished tiles, glazed tiles and antique tiles. The production process generally follows the traditional wet spray drying powder making process. Since the moisture content of the mud in the wet pulverizing process is mostly between 35% and 45%, it is necessary to evaporate more than 30% of the mud water in the process of spray tower pulverization, and the material powder with a moisture content of 7.0% to 8.0% can be obtained. Compacted in automatic hydraulic press. The principle is: the mud material flows into the spray drying tower for drying and dehydration. The principle...
