Autoclaved aerated concrete production plants

1. Utilisation of factory space

In comparison to other plant concepts, here we could reduce the required factory space by almost 30 %.

2. Significant savings on the foundations

Unbelievable but true, almost 90% of all foundation pits have been eliminated!

3. Hydraulics

Hydraulic components could be reduced by 60% and have been replaced by electromechanical devices

4. Electric control modules

Intelligent newly developed electric control modules: facilitate the highly feasible production process including self managing machine control and predictive maintenance tools. The plants reach highest overall equipment effectiveness (OEE) figures and fastest possible cycle times of the individual plant sections.

5. Cutting line

An all new and highly sophisticated cutting line has been designed.

The uniform distribution of cutting wires in a very long cutting machine reduces stress applied on the cake during cutting of thin blocks and panels. Therefore, the thickness cutter length has almost been doubled.

Wires and knives are automatically cleaned to enhance the cutting surface and to avoid that sticking material can draw the wires aside.

The side trimmer (cutting length and profiling) comes with a new design for "quick-change" cutting knives and automatic knife cleaning devices.

6. Process

The plant uses green cake separating technology as in many other Wehrhahn plants.

A brand new curing station between cutting and green cake separating allows the cake to harden prior to separating.

This reduces the risk of causing marks on the blocks and provides more flexibility for the hardness of the cake during cutting.

In SMART plants the cake is tilted back into the horizontal position after cutting to enable green cake separating before autoclaving. In addition, it is possible to produce panels with super-smooth surfaces.

It is the only AAC production plant on the market which produces cakes autoclaved in upright position without system waste. This results in an optimal cost benefit ratio and maximum capacity operation. The main features of the PLUS plant are its compact plant design and easy handling of the AAC in the packing plant.
