The invention provides a manufacturing production line of new material rich mineral paper. The manufacturing production line of the new material rich mineral paper is characterized by comprising a vacuum feeding machine, wherein the vacuum feeding machine is connected to a conical twin screw extruder, the conical twin screw extruder is connected to a plate type hydraulic screen exchanger, the plate type hydraulic screen exchanger is connected to a T-die extrusion die, the T-die extrusion die is connected to a four-roller calender, the output end of the four-roller calender is connected to guiding-out devices, the guiding-out devices are connected to cooling and shaping devices, the cooling and shaping devices are connected to a trimming and traction device, the trimming and traction deviceis connected to a laser thickness gauge, and the laser thickness gauge is connected to a double-station coiling machine. The manufacturing production line of the new material rich mineral paper has the advantages of utilizing the hot ductility of sheet materials of HDPE and mountain flour, mixing, feeding, heating, filtering and extruding sheet-shaped products are performance through a sheet extrusion device, the product is then thinned through the calender, the product can effectively reach the ideal thickness, and the surface smoothness of the sheet material is guaranteed; and the sheet material is cooled and shaped through a cooling roller, and then the sheet material is free of shrinkage, wrinkling and the like.
