Lightweight high-frequency partition wall extruder

JQT Series Lightweight High-Frequency Partition Wall Extruder

1. Introduction

The JQT Series Lightweight High-Frequency Partition Wall Extruder is an advanced forming machine specially developed for producing lightweight concrete partition wall panels. It integrates multiple traditional production processes—such as manual mold pulling, ground molding, and vertical molding—into one continuous extrusion process.

The equipment uses either ordinary Portland cement or silicate cement as the binding agent, and low-carbon steel wires as the reinforcement material. Various lightweight aggregates such as expanded perlite, ceramsite, slag, fly ash, water slag, and river sand are used to form the concrete mix.

This innovative extrusion technology replaces multiple manual operations, enabling one-time molding of wall panels with high precision and excellent compaction. As a result, it effectively reduces production costs, improves panel quality, and enhances overall manufacturing efficiency. The JQT model is recognized as the core equipment for lightweight partition wall production in modern precast concrete plants.

2. Supporting Equipment for the JQT Series

To ensure stable and efficient production, the JQT Lightweight High-Frequency Partition Wall Extruder is typically paired with the following auxiliary machines:

• Lightweight aggregate concrete mixer
• Dedicated cutting machine
• Crusher
• Electric material transport cart
• Panel transport trolley
• Panel lifting cart
• Wire winding rack
• Panel hoisting machine

These auxiliary machines work seamlessly with the main extruder to achieve automated and continuous wall panel production.

3. Working Principle

The JQT Lightweight High-Frequency Partition Wall Extruder combines multiple functions—material feeding, vibration, forming, and demolding—into a single compact machine.

The main motor transmits power through a pulley to the gearbox, whose output shaft drives the spiral mixing blades inside the forming chamber. The forming system consists of the machine frame, vibration unit, and base platform, creating a high-frequency extrusion cavity.

The lightweight concrete mix enters the forming chamber from the hopper. Inside, the spiral blades rotate continuously, pushing and compacting the material while the vibrator provides consistent high-frequency vibration. Under this dual action of screw extrusion and vibration, the material is compacted through resonance, forming dense, uniform wall panels with precise dimensions.

The reaction force generated by the compacted panels helps push the entire extruder forward, achieving continuous extrusion. Finally, a shaping scraper at the tail end smooths the surface of the newly formed panels, creating a fine finish ready for curing.

5. Key Features and Advantages

1. High Efficiency – The machine can extrude wall panels at a speed of 0.8–3.2 meters per minute, significantly improving production capacity.
2. Uniform Density and Strength – The panel compaction is highly consistent. The optimized design eliminates weak zones where left and right spiral blades meet, preventing cracks after installation.
3. High Automation Level – Equipped with a hydraulic lifting system, the extruder offers smoother operation and reduced manual labor.
4. Raw Material Savings – Broken or leftover steel wires can be manually reconnected and reused. Panels can be extruded continuously up to the reinforcing bar ends, minimizing waste of both steel and concrete mix, and improving platform utilization efficiency.
5. No Need for Steel Channel Rails – The extruder operates smoothly on a flat base without additional rail installation. This reduces base manufacturing cost and complexity while improving precision.
6. Long Service Life – The key wear-resistant components are built for durability:
   • Spiral mixing blades: over 80,000 meters of continuous production
   • Vibration plate: over 100,000 meters
   • Sidewall plates: over 60,000 meters

   The JQT extruder is equipped with alloy spiral blades, high-strength wear plates, and a reinforced alloy tail plate, ensuring excellent abrasion resistance and extended equipment lifespan.
