The invention relates to a low-temperature solidified
powder production line system and a production process thereof. The
production line system comprises a mixer, an extruder, a roller type tablet press, a
cyclone separator and a stirring tank which are sequentially arranged according to a production process
route. The production process comprises the following steps: S1, low-temperature mixing;S2, low-temperature
extrusion; S3, tabletting at low temperature; S4, separation; S5, stirring; and S6, low-temperature
grinding. Transformation is carried out on the basis of existing
powder coatingproduction line equipment, so that the material temperature in each process node is controllable and adjustable, and the
powder coating production line equipment can be suitable for the production characteristic of low-temperature solidified powder. In the technological process, different temperature parameters are set for mixing,
extrusion and tabletting respectively, so that the materials alwayskeep good properties on the technological
route, and finally, the materials meet the
grinding requirements through the
quenching process of heating and cooling in sequence in the stirring tank.
