SIMI plants for recycling of concrete consist of one device for crushing the concrete and separate aggregates from cement. The aggregates return to the landfill, while the grout is deposited in the pool and diluted with clean water during rinsing. The whole process is automatic programmed for various regimes of the work (summer, winter, low temperatures; etc.). Recycled cement water will be held in liquid form through the mixer, which according to the program keeps it in constant liquid. The same cement water returns to the process of concrete production through the balance of the water. With this mode, the cycle is closed and there is no run-off water from washing into waterways, and therefore no pollution of the same with additives that are added to the concrete.
