The steel-plastic geogrid strip extruder is a specialized piece of equipment designed for the continuous production of high-strength steel-plastic composite geogrid strips. It heats, melts, and extrudes raw materials (such as PP and HDPE), synchronously compounding them with steel wires or steel strips to form structurally stable and dimensionally precise geogrid strips. The machine features advanced precision screws, an efficient temperature control system, and intelligent PLC control technology, ensuring excellent tensile strength and elongation properties. It is widely used in the production of reinforcement materials for infrastructure projects such as highways, railways, water conservancy, and mining.

Key Components and Features of the Ruimin Geogrid Extruder
Equipment Configuration:
Wire Coil Rack
Used for storing wire coils, each rack can hold 20 coils, made of steel structure with welding.
SJ-75/30 Single Screw Extruder
Specific Requirements:
Due to the use of optimized screw and new slotted barrel design, the extruder has the following advantages: high plasticization rate, uniform melt, and continuous stable production. It also features a high-performance gearbox reducer with large torque, long life, and low noise.

Mold (10mm-16mm) 1 set
Made of high-quality mold steel, with a compact structure, reasonable connections, and easy replacement.
Cooling Tank
The cooling tank is used to control the crystallinity of the plastic and ensure the elongation rate of the billet during stretching. The tank body is made of stainless steel.
The tank uses a circulating water system and is equipped with an inlet, outlet, and overflow. The circulating water pump draws water from the water tank through the filtration system, water cooling system, dual-channel water pipeline, and spray pipeline, spraying cooling water.
Powerful Vacuum Water Removal System: A powerful suction fan extracts moisture from the surface of the strips. The extracted water is then separated by a water-vapor separator and returned to the water tank for recycling.
Main Parameters:
Double Roller Embossing Traction Machine
Used for the first traction after extrusion cooling, composed of a motor, reducer, traction rollers, and gears, with variable frequency speed regulation. Helical gear transmission ensures smooth operation, low noise, and no vibration.
Duplex Winder
Used for winding products, forming rolls, and length measurement with automatic center alignment and winding. It consists of a winding disc, transmission device, frame, and electrical control.
Control and Electrical Cabinet
All units of the production line, including feeding, extrusion, and traction, are integrated into the control system. The entire line can be operated in linkage mode or each unit can be controlled independently. A mechanical trigger switch can be used to stop the machine and sound an alarm in case of a line break.
