Inside the reactor, the burnt lime is slaked by means of adding water, and calcium hydroxide is generated thus. As this is an exothermic reaction – heat is generated – the temperature of the sand lime compound rises. It is particularly important to determine the volume of the reactor correctly, as the slaking process causes an expansion of the compound. The slaking speed of the burnt lime and the material consumption of the corresponding sand lime brick press have to be considered for the calculation of the reactor volume. The slaking reaction has to be completed inside the reactor, otherwise, the compound will expand further after the compaction in the press. This will then lead to damages, that is, cracks in the finished products.
The correct volume and the correct structure of the Masa reactors provide for a continuous material flow with complete utilization of the reactor. The special Masa reactor discharge system guarantees an optimum adaption of the required compound quantities to the consumption of the presses.
