working principle of a cement plant

Concrete batching plant is divided into four parts: sand feeding, powder (cement, fly ash and expansive agent etc.), water and feed additive feeding, mixing and transmission storage. Its working process is shown in Figure 1, the electric mixer control system after entering the man-machine dialogue interface. The system initialization process, including the formula, the grade of concrete, the slump, the production volume. According to the weighing hopper, a metering hopper is detected, the output of empty material or material with signal, prompts the operator to determine whether to start mixing control procedures. Start the sand and stone belt motor feeding metering hopper; butterfly valve open fly ash, cement tank, transportation of fly ash and cement to the metering hopper start screw machine motor; control valve open water storage and pool water and admixture admixture into the metering hopper. The measurement meets the design requirements after the opening of Doumen into the metering hopper, ingredients Into the start of the concrete mixer mixing, to set the time to open the mixer door, concrete into the mixing car of the mixture.
