The pellet production line is an automated production line that processes raw materials into finished pellets that meet user requirements under fully sealed conditions. The raw materials are manually fed into the unloading station, and after unloading, they are transported to the mixing bin for thorough mixing. Then, they are conveyed to the wet mixing bin by a vacuum feeder according to the appropriate ratio, and finally transported to the extrusion and rolling integrated machine by screw conveyors. The produced pellets are dried by a vibration dryer, screened out to meet the requirements, stored in the finished product warehouse, weighed and measured, inspected, and packaged as finished products. At the same time, products that have been screened and found to be unqualified are returned to the wet mixer for secondary processing.

Process Introduction

The pellet production line is an automated production line that processes raw materials into finished pellets that meet user requirements under fully sealed conditions. The raw materials are manually fed into the discharging station, and after discharging, they are transported to the mixing bin for thorough mixing. Then, they are conveyed to the wet mixing bin by a vacuum feeder according to the appropriate ratio, and finally transported to the integrated extrusion and spheronization machine by screw conveyors. The produced pellets are dried by a vibration dryer, screened out to meet the requirements, stored in the finished product warehouse, weighed and measured, inspected, and packaged as finished products. At the same time, products that have been screened and found to be unqualified are returned to the wet mixer for secondary processing.

The entire production process operates under sealed conditions, without pollution, and is fully controlled by PLC automatic control, meeting the requirements of the new GMP certification.
