Granulation equipment, system and process for dry milling process for low-water-absorption-rate glazed tiles

The invention discloses granulation equipment, system and process for a dry milling process for low-water-absorption-rate glazed tiles and belongs to the field of ceramic raw materials. The granulation equipment for the dry milling process for the low-water-absorption-rate glazed tiles comprises a shell and a double-layer rotary disc installed in the shell. The double-layer rotary disc comprises an upper layer material dispersing disc and a second layer disc which are distributed vertically. The second layer disc can receive particles rolling off from the upper layer material dispersing disc.The double-layer rotary disc is driven by a driving device. A feed pipe and a atomization spray gun are arranged above the double-layer rotary disc. Baffling air rings are distributed at the edge of the upper layer material dispersing disc. The side face of the second layer disc is provided with an air inlet and a discharge outlet. The upper portion of the shell is provided with an air outlet. Thegrain forming process of
