Granulation Extruder
This Granulation Extruder is equipment used to pelletize raw materials in industries such as plastics, chemicals, and food. Through processes like heating, melting, and extrusion, it processes materials into uniform particles of specific shapes and sizes. Widely applied in plastic recycling, plastic processing, fertilizer production, and feed manufacturing, it converts waste, recycled materials, or raw materials into uniform particles for downstream processes via appropriate processing methods. Common granulation techniques include wet, dry, and extrusion granulation. Extrusion granulators shape materials through compression and cut them into particles using a cutting system. The equipment improves material utilization, reduces production costs, ensures consistent particle quality and density, and meets strict industry requirements for material form and quality. It features simple operation, easy maintenance, and is indispensable in modern manufacturing.

Product Introduction
Technical Background
- Technological Evolution: Granulation technology originated in the early 20th century for plastic processing. Single-screw extruders established foundational structures (e.g., 45mm screws achieving 15-30 kg/h output for ABS/PE). Post-1980s twin-screw technology enhanced mixing via intermeshing screws, addressing impurities in recycled materials and enabling engineering plastics (PEEK, PA66) processing under high-temperature shear.
- Industry Needs: Environmental policies drive recycled plastic granulation (>40% market share), necessitating advanced filtration (removable multi-layer screens) and dynamic mixing (barrier screws + reciprocating agitation). High-purity materials (ash <0.01%) for新能源/electronics demand twin-stage extrusion (melting + vacuum devolatilization) and nano-filler dispersion.
- Trends: Smart PLC integration with real-time monitoring (melt pressure sensors ±0.5MPa), electromagnetic heating (30-70% energy saving), modular designs for quick screen changes (Haff connectors) and multi-size switching (1-5mm particles). Emerging methods include supercritical fluid-assisted granulation (ScCO₂ viscosity reduction) and biodegradable material screws (low-shear anti-degradation).
Structural Composition
Extruder:
- Screw and Barrel: The screw is responsible for plasticizing and extruding plastic raw materials. The barrel is usually made of high – temperature – resistant materials to withstand high – temperature and high – pressure environments.
- Motor: Drives the screw to rotate and provides the required power.
- Heating Device: Multi – stage heaters provide the required temperature control to ensure effective plasticization of plastics.
- Mold: A mold customized according to the pipe specifications is responsible for shaping the molten plastic into a pipe. The mold design affects the diameter and wall thickness of the pipe.
