A pore-forming microsphere homogenizing device and method include steps of: firstly homogenizing the pore-forming microspheres made of the cow dung into the clay paste; secondly homogenizing the materials by using the kneading gear and the ejection cylinder rotating in opposite directions for kneading the clay paste while ejecting the pore-forming microspheres; and thirdly homogenizing the materials by using the telescopic kneading part and the ejection cylinder together for further kneading the clay paste while ejecting the pore-forming microspheres. With the foregoing processes, uniform and complete closed pores are uniformly distributed in the clay bricks, so that the strength of the clay bricks remains unchanged while clay usage is reduced.
