Abstract：In light of the low level of automation of the current screening equipment commonly used in the tungsten
and molybdenum industry，a fully automatic screening platform fitted with a screw feeder has been designed
by means of model selection，and its parameter design takes into account the characteristics of tungsten powder
and molybdenum powder，realizes the stepless adjustment of the screening speed and the automatic screening of
tungsten powder and molybdenum powder，reduces the labor intensity of workers，improves the production efficiency，
and decreases the damage of dust to the environment and workers.
