Raw material storage, dosing, and mixing
Sand lime bricks consist of the two raw materials sand and lime only. For the manufacturing process, water is required in addition. The raw materials that are mostly supplied from local extraction places are stored separately in raw material silos. On the way to the silos, the sand passes a screening station to separate oversize material.
Hawk sand lime brick making plants are designed to use at least two different types of sand. The advantage for the customers is that the product quality can directly be influenced by a specific mixture of the different types of sand.
The raw materials sand, lime, and water are exactly dosed and weighed in individual scales and fed into the intensive mixer. In the mixing process, a homogeneous and highly disperse sand lime compound is generated.
The complete automatic process is controlled and monitored via the Hawk mixing plant control system .
