Introduction to the Features and Operating Principle of a Granulator for Used Woven Bags
Time：
2017-07-22
Features: 1. This unit can process cleaned and shredded recycled nonwoven fabrics, woven bags, and waste polyethylene and polypropylene plastics into pellets, which serve as feedstock for subsequent molding operations. 2. The extruder gearbox in this unit is a hardened‑gear reducer made from 28O‑grade alloy steel. 3. The screw and barrel are crafted from 40Cr alloy steel and undergo nitriding treatment, ensuring a long service life. 4. The system comprises a main and auxiliary extruder, a water tank, and an alloy rotary‑blade pelletizer; a drying blower can also be optionally equipped to meet user requirements. 5. From raw material crushing and washing through feeding to final pellet production, the entire process is fully automated. 6. It makes full use of a high‑pressure friction‑based continuous heating system.
Features:
1. This unit can process cleaned and shredded recycled nonwoven fabrics and woven bags, as well as waste polyethylene and polypropylene plastics, into pellets that serve as raw material for re‑molding operations.
2. The extruder reducer of this unit is a hardened-gear reducer manufactured from 28O-grade alloy steel.
3. The screw and barrel are made of 40Cr alloy steel and undergo nitriding treatment, ensuring a long service life.
4. This production line consists of a main extruder, an auxiliary extruder, a water tank, and an alloy rotary‑blade pelletizer. A drying blower can also be supplied upon customer request.
5. From raw material crushing, washing, and feeding to pelletizing, the entire process is fully automated.
6. Fully leverages a high-pressure friction–based continuous heating system to enable automated production heating, eliminating the need for intermittent heating and thereby saving electricity and conserving energy.
Working principle:
After waste plastics are crushed, an automatic feeder conveys the material into the feeding hopper. The feeder then forcibly and uniformly feeds the material into the main screw of the plastic pelletizing machine, where it undergoes plasticization. Under the combined action of compression and extrusion by the screw and external heating, the material is subjected to mixing and plasticization. As temperature and pressure gradually increase, it enters a viscous flow state and is conveyed at a specified pressure.
Pass through the die head, extrude and pelletize to obtain particles of the desired shape.
