The main components of a concrete mixing plant include five systems: the mixing main unit, material weighing system, material conveying system, material storage system, and control system, as well as other ancillary facilities. These components work together to ensure the normal operation of the mixing plant, and in this working process, it can be mainly divided into the following steps.
1. Material metering: Raw materials such as aggregates, cement, and fly ash are put into the discharge port, and the metering device measures according to the mix ratio. The measured aggregates are transported to the waiting hopper on the upper part of the mixer by a belt conveyor, while cement and fly ash are transported to their respective metering hoppers by a screw conveyor.
2. Material transportation: After metering, the control system issues a command to stop the working of each running part and start feeding materials into the mixer in sequence for mixing. Water and admixtures are respectively pumped to their respective metering hoppers by a water pump and an admixture pump for metering.
3. Mixing: The raw materials are mixed and stirred in the mixer. After completion, the mixer's discharge door is opened, and the concrete is unloaded into the mixer truck through the discharge hopper, and then enters the next working cycle.
