Preparation of raw materials
A ball mill wet-grinds the quartz sand with water to a sand slurry.
Reinforcement preparation
HESS AAC SYSTEMS plants are ideal for the production of large format reinforced assembly components.
Tilting back and green separation
The HESS AAC SYSTEMS plants have combined the advantages of the tilt-cake and flat-cake system.
Autoclaving
In the autoclaves the cakes are cured for ca. 10–12 hours at a temperature of 190° C with saturated steam at a pressure of 12 bar.
