Raw materials processing

When manufacturing sand lime bricks, even the initial preparation of the raw materials is of the utmost importance. This lays the foundation for producing a high-quality end product. All our systems in the raw materials processing area are designed to produce a perfect and durable sand lime brick when it exits the process. Our raw materials processing facility consists of the following systems:

  • Sanding, sieving and bunkering system
  • Silo
  • Transport and dosing system (with scale)
  • Pre-mixer
  • Reactor
  • Remixer
  • Colour mixing plant (optional if coloured sand-lime bricks are to be produced)
  • Electric control system.

WKB Systems plants are designed to process the traditional raw materials, namely sand and lime, as well as alternatives such as fly ash or cement. For our customers, this offers the benefit of being able to influence the product quality and consistency any way they want. This provides the end customers with a wider range of products to choose from.

From the sieving station, the sorted raw materials arrive in the silos. From there they are transported to the pre-mixer via the conveyor and dosing system, which doses the raw materials precisely. Here, water is fed to the still dry raw material mix. Thanks to our electronically controlled weighing technology as well as the continuous moisture measurement of the sand, we are able to produce a highly dispersed homogeneous mixture. The sand ime brick is produced exactly according to the provided recipe by this technique.

Our electric control system can be used in every single production area. It contains hardware and software components that are necessary for maintaining an automatic production process. In addition, the interface for the corresponding signal exchange is also integrated. The built-in router connection allows remote diagnostics in the event of a fault. The electric control system is subdivided into individual areas, each of which is equipped with its own control panel (touch panel). The individual areas communicate with each other via Profinet or Ethernet. The setting of the individual control panels takes place in each case in the immediate vicinity of the machine / system components they are associated with.
