Versatile Twin-Shaft Mixing Extruder for Various Material Mixing

Twin-Shaft Mixing Extruder

“A twin-shaft mixing extruder is an integrated processing equipment that combines mixing and pre-extrusion functions. It features two counter-rotating shafts with mixing blades that homogenize clay or raw materials while simultaneously compacting and pre-shaping the mixture through an extrusion section. This dual-function design significantly improves material uniformity and prepares the clay for subsequent vacuum extrusion in brick/tile production lines.”

Technical Data

Introduction to Twin-Shaft Mixing Extruder Equipment

The twin-shaft mixing extruder is a core raw material processing equipment in the brick, tile, ceramic, and building materials industries, integrating high-efficiency mixing and pre-extrusion molding functions. This equipment adopts a counter-rotating twin-shaft design equipped with wear-resistant alloy mixing blades, capable of powerfully crushing and homogenizing raw materials such as clay, shale, and coal gangue. Simultaneously, it achieves preliminary compaction and plasticization of materials through the extrusion section at the discharge end, significantly improving the forming efficiency of subsequent vacuum extruders.

Core Advantages:

1. Twin-Shaft Forced Mixing: Compared to single-shaft equipment, mixing uniformity is increased by over 40%, enabling dead-zone-free processing of high-viscosity materials.

2. Integrated Extrusion: Features an adjustable discharge outlet to output pre-compressed continuous material flow, reducing energy consumption of vacuum extruders.

3. Intelligent Adaptability: Supports variable frequency speed regulation (0-35 rpm adjustable) to meet process requirements of materials with different plasticity levels.

4. Industry 4.0 Compatibility: Equipped with pressure sensors and PLC interfaces for integration into automated production line control systems.

Typical Applications:
Suitable for raw material pre-processing in the production of fired bricks, hollow bricks, tiles, and other products. Particularly effective for processing recycled materials containing impurities or uneven moisture content (e.g., construction waste, river silt, etc.), with processing capacities ranging from 5 to 80 tons/hour (depending on model specifications).
