The operating mode of the RBU is fully automatic according to the “one button” principle. The BP-2G-2250s twin-shaft concrete mixer is installed on the overpass, at a discharge height of 4 meters of the finished mixture. The concrete mixer is equipped with a special bucket (skip) for lifting and loading the mixture components inside the concrete mixer. The concrete mixer is equipped with imported components: LikeDrive planetary gearboxes, electric motor. The skip of the concrete mixer has a bottom shutter to reduce dusting and increase the discharge speed. For storage and accurate dosing of inert dosing complex DKM-60 is intended. It is possible to supply bunkers of increased volume (up to 80 cubic meters). Inert are loaded and stored in bunkers, the number of bins 3 to 20 cubic meters. meters, the total volume of bunkers is 60 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 you set the required dose of inert, the conveyor is turned on and the metered components are fed into the skip (bucket) of the concrete mixer. The skip rises and feeds the components into 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). Cement auger, BD-90 batcher block, which consists of a cement dispenser for 900 kg, water for 300 liters and a chemical additive dispenser for 40 liters, are used to supply cement from silo to the metering unit. 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 a concrete truck or receiving hopper. Next, the cycle repeats. In one cycle, the production of 1.5 cubic meters. meters of finished concrete or mortar, the cycle lasts no more than 60 seconds. Productivity of the installation is 60 ... 90 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.
