Hengde – Solution for the Retrofit Project of Autoclaved Aerated Concrete Block Equipment to Produce Self-Insulating Masonry Blocks

The project solution for transforming autoclaved aerated concrete block equipment into a self-insulating block production line is designed to help enterprises achieve product transformation through technological upgrades, enhance their market competitiveness, and meet the requirements of green building development.

Guangzhou Hengde has developed a mature, comprehensive solution in the field of upgrading and retrofitting autoclaved aerated concrete equipment. Its self-insulating block project boasts the following technical features and implementation results:

I. Core Technical Solution for the Project

Cutting Process Upgrade

The cutting system of conventional autoclaved aerated concrete (AAC) block equipment has been optimized by adopting an innovatively designed 4.2-meter mold-box process cutting line and a stacking and packaging line. By improving cutting processes such as disc sawing and reciprocating sawing, the yield rate and cutting accuracy have been significantly enhanced.

German CLC block technology integration

We have introduced the non-autoclaved CLC block production technology from Germany’s Luka Company, combined with a resource utilization plan for industrial tailings and construction waste, to achieve a no-high-temperature autoclaving curing process. This approach reduces energy consumption while enhancing both the strength and waterproof performance of the products.

Industrial Boiler Compatibility Retrofit

Retain the original steam-curing system and upgrade it to an industrial energy-saving boiler. By optimizing the batching system and curing process, achieve compliance with emission standards for pollutants and meet environmental protection policy requirements.

Multi-category adaptive production

The upgraded production line supports the manufacture of various product categories, including homogeneous self-insulating blocks, composite self-insulating blocks, and ceramsite blocks, enabling a flexible investment model with multi-purpose machinery.

II. Advantages of Project Implementation

Cost Control: By making reasonable reuse of existing factory buildings and some equipment, the renovation costs have been reduced by 30%-40%, and the renovation period has been shortened to within 30 days.

Environmental benefits: The production process reduces coal consumption, and the comprehensive utilization rate of industrial solid waste reaches over 85%, meeting the building energy-saving standard of 85%.

Technical versatility: Adapts to different mold box specifications (square molds, long molds), meeting the production needs of derivative products such as ceramic aggregate blocks and lightweight partition panels.

The project has been scaled up and applied in regions including Xinjiang, Zhejiang, Inner Mongolia, and Gansu. After the transformation, production line capacity and efficiency have significantly improved, and product quality has passed the testing under the national energy-saving building materials certification system.
