It's a long way from raw materials through the mixture to the finished stone. Many plant components are involved in this process. Only if the system components are matched, can one be assured of a smooth process and economical operation of the block making plant.
The manufacturing of autoclaved aerated concrete products demands high standards for mixing and dosing of the aggregates, the control of the fermentation process and the control of each production step. Masa's aerated concrete installations are proven advanced technology processes, designed according to customers specific requirements. This approach allows complete solutions to ensure highly efficient, optimised processes resulting in consistent final product quality.
It's a long way from raw materials through the mixture to the finished sand lime bricks. Many plant components are involved in this process. Only if the system components are matched, can one be assured of a smooth process and economical operation of the sand lime brick production plant.
It's a long way from raw materials over mixture to the finished (Kerb)stone. Masa Kerbstone presses were developed to fulfill among other criteria, the special requirements of the "British Standard" kerbstones. This "British Standard" is still a condition in countries of the Middle East and the UK.
Masa plants and machines are installed and commissioned by our own experienced fitters. Masa relies on qualified personnel, trained in Germany.
The Masa Lifetime service extends far beyond the actual assembly and commissioning of a plant. Masa can rely on specific know-how and an industry experience of more than 110 years.
Do you need support with your machine? Masa Support scores in both quality and significantly improved accessibility. Whether "first aid" for technical problems, updates, functional expansions of your production plant or technical questions, the know-how provided by Masa Support covers a wide range of services.
One of the keys to increasing productivity and quality is continuous training of the machine and maintenance personnel.

Masa pre-cutting plant
The fresh aerated concrete cake is cut by means of cutting wires and specially designed plane cutting knives to the required block length. The block length can be varied via a central adjustment unit.
Masa tongue and groove profiling station
The optimum profiling of tongue and groove is achieved by two lined up profiling knives. Thus, a particularly smooth and fine structure of the tongue and groove can be generated.
The shapes of the profiles can be varied by means of a knife quick change device. Two types of knife are mounted on the quick change device. They can be turned into the working area as required.
Masa longitudinal cutting plant
In this device, the fresh aerated concrete cakes are cut into up to 15 layers by means of steel wires. Thus, the width of the aerated concrete block (that is, the wall thickness) is produced. The product sizes can vary from 50 mm to 500 mm in steps of 5 mm.
To make the most efficient use of the net volume of aerated concrete cake, it is possible to make a so-called "mixed cut". Therefore it is possible to produce two different thicknesses (= wall thicknesses) in one step.
Each individual cutting wire is tensioned by means of pneumatic cylinders enabling highly precise cuts to be achieved. A wire breakage detection device automatically signals possible wire breakages.
Masa cross cutting plant/ recessed grip mill
The cross cutting plant cuts the layers to the height of the aerated concrete block. The vertical cut is carried out by means of a lowerable cutting frame. In oscillating movements, the pneumatically tensioned cutting wires are moved through the fresh aerated concrete cake from top to bottom at preset distances. A wire breakage detection device automatically signals possible wire breakages.
The top layer, the so-called "cap", is removed by means of an integrated cap suction device. A suction hood takes off the complete cap (with a length of 6 m) from the cut block. The cap falls into the cutting trench as soon as the cake has left the cross cutting plant. The waste from the front sides of the aerated concrete cakes is cut off by a fly cutter. This material, too, falls into the cutting trench to be recycled .
Optionally, an integrated mill can cut recessed grips into the aerated concrete blocks.
