Lightweight aggregate composite self-insulating block equipment, Hengde develops a new process for lightweight aggregate foam concrete block equipment


Guangzhou Hengde's expanded clay block equipment has become a benchmark solution in the field of building energy conservation through technological integration, environmentally friendly design, and intelligent upgrades.

Guangzhou Hengde's ceramsite block equipment demonstrates the following core advantages at the technical level:

1. Localization of German technology and process innovation

1. Application of CLC technology

Using the CLC (foam concrete) technology authorized by Germany's LUCA company, combined with the optimization of the foaming process based on domestic raw material characteristics, achieving non-autoclaved environmentally friendly production. The product strength can reach over 10.5MPa, without the need for high-temperature curing, reducing energy consumption by 76%.

2. Composite closed-cell structure

Through the vibration compaction technology of the new mixer, the uniformity of ceramsite particle distribution reaches 95%, forming independent closed micropores inside the blocks, with a thermal conductivity ≤0.055W/(m·K) and water absorption only one-quarter that of traditional blocks.

2. Intelligent and automated production

1. Full-process CNC system

Equipped with a PLC control system and touch screen interface, realizing full-process automation including batching, mixing, molding, and cutting. Daily output can reach 100-1000 cubic meters, reducing manual intervention by 70%.

2. High-precision cutting technology

Using a high-speed, high-precision CNC cutting system with dimensional accuracy of ±0.5mm/m, supporting dust-free dry and wet cutting processes, with a defect rate below 0.3%.

3. Environmental protection and comprehensive resource utilization

1. Adaptability to solid waste raw materials

Supports production using industrial solid wastes such as fly ash, slag, and construction waste, achieving a resource utilization rate of 95%, complying with national green building policies.

2. Low-carbon production mode

Uses air energy steam technology, requiring no coal during curing, with no exhaust gas or wastewater emissions during production, and noise ≤65dB(A).

4. Performance advantages of ceramsite block products

1. Lightweight and high strength

Ceramsite blocks have a density of 400-800kg/m3, reducing building load by 20%-60%, and improving construction efficiency by 30%.

2. Multifunctional integration

One machine can switch to produce more than 10 types of products including ordinary blocks, partition boards, and self-insulating blocks, reducing initial investment costs.

3. Energy-saving insulation and soundproofing

Products feature self-insulation (meeting 65% energy-saving standards) and excellent sound insulation, suitable for hot summer and cold winter regions.

5. Service and market validation

1. Full lifecycle support

Provides full-process services including plant planning, equipment upgrading, and remote diagnostics, with a 5-year warranty on core components.

2. Global application cases

Equipment exported to Central Asia, Southeast Asia, Africa, and other regions, applied in various construction projects, with customers able to profit within 3 months of production.

In summary, Guangzhou Hengde's ceramsite block equipment, through technology integration, environmentally friendly design, and intelligent upgrades, has become a benchmark solution in the field of building energy efficiency.
