The invention relates to a pulse type airflow mixer. The pulse type airflow mixer comprises a powder particle feed port, a pulse bin top dust remover and a mixture bin. The powder particle feed port is formed in the top of the mixture bin, the pulse bin top dust remover is arranged beside the powder particle feed port, the bottom of the mixture bin is set in a conical shape, airflow mixing head nozzles are connected to the bottom of the mixture bin in a circle and connected with high-pressure air pipes, the high-pressure air pipes are communicated with an annular air bag through electromagnetic valves, and a butterfly valve is arranged at the bottom of the mixture bin. The mixing and homogenizing speed is high, products are not broken, high efficiency and energy saving are achieved, and the mixing and homogenizing value is high.
