The utility model relates to a production equipment of column shaped polymer compound additive, comprising an extrusion device and a geared granulator. By using that the melting points of all the components of additive mixtures are different, low-melting material can be melted in extrusion process in extrusion device to get material with certain viscosity and plasticity which is entered into the granulator to be granulated through the die gap of the extrusion device. By the utility model, the compound plastic additive of granular with diameter of 1. 0-8. 0mm can be produced. The utility model is evidently characterized in that the burning of polymer additive can be avoided, the shape rate and the mechanical strength of the additive are high, and the granularity can be adjusted according to requirements.
