Mortar-concrete unit operation mode: fully automatic according to the “one button” principle. The BP-2G-3000 twin-shaft concrete mixer is installed on the overpass, at the unloading height of the finished mixture 4.2 meters. The concrete mixer is equipped with a special reinforced belt conveyor for loading inert materials into the concrete mixer. For storage and accurate dosing of inert dosing complex DKM-80 is intended. Inert are loaded and stored in bunkers, the number of bins 4 to 20 cubic meters. meters, the total volume of bunkers 72 cubic meters. meters. A belt conveyor-dispenser is installed under the hoppers, on which the exact dosage of the components takes place, the components are fed from the hoppers by opening the slide gates, the gates are controlled by the Camozzi pneumatic system (Italy). When the necessary dose of inert is selected, the conveyor is switched on and the metered components are fed to the belt conveyor. The mixture rises along the conveyor and enters the mixing chamber of the concrete mixer. Cement is stored in a special warehouse - cement silo (not included in the basic package). The silo for cement must be selected based on the two daily supply capacity. To supply cement from a silo to a cement dispenser, it is necessary to purchase a screw of the required length. Cement silos, silo harness and screws are always available in stock in Zlatoust! Manufacturer "SCUTTI" (Italy) Using a cement screw, it is fed into the batcher block BD-120, which consists of a cement dispenser for 1200 kg, water for 550 liters and a chemical additive dispenser for 80 liters. Each dispenser is located on three high-precision CAS strain gauges and a rigid frame, which increases the accuracy of dosing. The cement dispenser is equipped with an “OLI” vibrator to induce the flow of cement when it sticks. All components of the mixture are mixed, after obtaining the necessary homogeneity of the mixture, the Camozzi air lock of the concrete mixer opens and the mixture is fed into the concrete mixer or the receiving hopper. Next, the cycle repeats. In one cycle, 2 cubic meters are produced. meters of finished concrete or mortar, the cycle lasts about 50 seconds. Productivity of the installation is 90 ... 144 cubic meters. meters of finished concrete or mortar per hour of work. Possible delivery of concrete plant in a protective coating of zinc. The coating is applied by cold galvanizing.
