Preparation process of ancient city wall-imitating brick

The invention relates to the technical field of manufacturing of city wall bricks, and discloses a preparation process of an ancient city wall-imitating brick. The present invention provides the following technical solution: a preparation process of an ancient city wall-imitating brick comprises the following raw materials in the following parts: 10-15 parts of clay, 10-15 parts of clay, 20-30 parts of shale, 4-6 parts of kaolinite, 4-6 parts of montmorillonite, 3-5 parts of illite, 3-5 parts of chlorite, 6-8 parts of calcite, 8-10 parts of hematite and 3-6 parts of albite. The preparation process comprises raw material selection, raw material processing, inclined surface formation, firing in a kiln and discharge out of the kiln. The preparation process of the ancient city wall-imitating brick has the advantages of reducing the particle size of the aggregate and ensuring the quality and strength of molding of a brick blank by finely grinding the raw materials, and effectively avoidingsubsequent cutting cost a
