Description

technical field [0001] The invention belongs to the technical field of mineral fiber sprayed cotton production, and in particular relates to a mixing and granulating equipment and a preparation method for producing mineral fiber granular cotton for hard spraying by using the matching production line of the equipment. Background technique [0002] Mineral fiber spraying technology originated in Europe and the United States, and was introduced to China in the late 1990s. In recent years, it has been widely and widely used in the domestic construction industry. Mineral fiber spraying is divided into soft spraying and hard spraying. Soft spraying uses a special inorganic fiber spraying machine to spray untreated mineral fiber granular cotton and a certain amount of water-soluble adhesive according to the required ratio. The granular cotton and glue solution are evenly mixed at the nozzle of the spray gun and sprayed on the substrate. The surface, after simple pressing, solidifi...
