Abstract

The invention discloses a large-sized paper-surface gypsum board production process with the annual yield of 60,000,000 square meters and a production line thereof. The process is simple; equipment and all automatic control systems of the production line are improved, so that the requirements on continuously increasing production volume are met, the annual yield reaches over 60,000,000 square meters, the speed reaches over 120 meters, and the technical blockades of similar foreign production lines are broken through; the aspects, such as heat energy utilization, flue gas emission treatment and waste scrap collection, are improved, so that energy saving and emission reducing are realized, and the pollution to the environment is reduced; the whole production line adopts the automatic control systems, so that the labor intensity of staff is reduced, the manual work is reduced, the production cost of enterprises is reduced, and the production efficiency and the rate of qualified products are increased.

Description

technical field [0001] The invention relates to the field of gypsum board production equipment, in particular to a large-scale gypsum board production process with an annual output of 60 million square meters and a production line thereof. Background technique [0002] Domestic gypsum board production is generally based on a scale of 20-30 million square meters, with a production speed of 30-65m / min. The use of raw materials, the use of heat sources, and specific drying, calcination, batching, mixing, molding, paper splicing, edge sealing, Various technical links such as waste board treatment and flue gas desulfurization cannot break through the existing technical bottlenecks. Therefore, the large-scale gypsum board equipment technology has not achieved the advanced production level abroad. In recent years, the domestic decoration market has developed rapidly, and the supply of gypsum board market has been in short supply. However, the characteristics of small scale, high e...
