What is an AAC Block Line?

An AAC production line is a complete automated system that processes raw materials, molds the slurry, cuts the blocks, and autoclaves them into lightweight, strong, thermally insulating building materials.

Key Benefits for New Zealand’s Market

Outstanding seismic performance (lightweight structure reduces seismic forces)
High fire resistance (up to 4 hours)
Superior thermal insulation, supporting NZ energy-efficiency regulations
Fast construction speed, ideal for large-scale housing
Eco-friendly materials, meeting green building policies

Configuration of 320,000 m3/year AAC Block Line in New Zealand

1. Raw Material Preparation System

High-capacity ball mill for sand slurry
Fully automated batching and dosing
Large-volume mixer for continuous feeding
→ Ensures stable density control for large-scale, uninterrupted production

2. Casting & Pre-Curing System

Expanded mold capacity
Intelligent temperature-controlled pre-curing chambers
→ Ideal for high-volume casting cycles (20–24 batches/day)

3. High-Precision Cutting Line

Intelligent cutter with automatic wire tension control
±0.5–1mm accuracy even at high capacity
→ Ensures consistent block dimensions for large commercial projects

4. Multiple Autoclave Lines

Several large-diameter autoclaves
Steam recycling & optimized curing curves
→ Minimizes energy cost and ensures uniform strength

5. Automated Handling & Packaging

Robotic stacker
Automated palletizing
Strapping & wrapping system
→ Reduces labor cost and improves production efficiency

6. Optional Upgrades for New Zealand

Dust removal system
ERP digital management
Automatic waste recycling system
