Ceramsite proppant preparation method

The invention discloses a preparation method of a ceramsite proppant, the ceramsite proppant contains 35-40 parts of aluminum ash, 30-38 parts of flint clay, 20-25 parts of kaolin, 10-20 parts of perlite, 8-15 parts of manganese ore, 5-8 parts of straw and 3-5 parts of 2, 5-furandicarboxylic acid (FDCA), and the preparation method comprises the following steps: firstly carrying out coarse crushing on the straw, and then carrying out ball milling to obtain 500-mesh powder; the flint clay, the kaolin, the perlite, the manganese ore and the FDCA are subjected to ball milling to obtain 500-mesh raw materials, then the raw materials are mixed in proportion, granulated and formed, the raw materials are dried through a belt dryer and then transferred to a rotary kiln to be fired, and the finished product is obtained.The ceramsite proppant prepared through the method has the advantages of being high in strength, low in density, good in stability and low in crushing rate, recycled raw materials are adopted, energy is
