In the related technology, a buffer tank and a shear tank are set to form a circulation loop, and water and other liquids are added to the buffer tank, so that the water and other liquids are first circulated in the circulation loop formed between the shear tank and the buffer tank, and the heat exchange system set on the circulation pipeline between the shear tank and the buffer tank is used for circulation heat exchange and temperature rise. When the temperature sensor detects that the water and other liquids in the circulation pipeline have reached a suitable temperature, the auxiliary materials are added to the shear tank to perform circulation shearing of the auxiliary materials, which can meet the requirements of large-scale auxiliary material shearing.
