The material feeding sequence in the production process of concrete mixing plant is particular

In the process of using concrete mixing plant equipment to mix concrete, sandstone aggregate, water, cement, fly ash and other materials are needed. Not only the proportion of various materials needs to be strictly matched, but the order of each material is also applied. It is also very important to affect the quality of the concrete produced. So what is the order of material delivery during the production of concrete concrete mixing plants? Why do you want to do this?

Concrete mixing plant

In the process of mixing concrete, the concrete mixing plant equipment will follow the preset procedure, according to the first stone, then the cement, then the sand and the water. These materials are weighed back and then enter the interior of the host through the conveyor system. The sequence is controlled by the mixing station control system. The order of such feeding is mainly to ensure that the various materials can be fully stirred and evenly stirred. Since the concrete mixing plant equipment mostly uses the forced mixer as the main machine, the discharge port is in the lower part of the main machine, so it is not possible to add water first. The dry material should be added slowly and uniformly to add water. The stones are looser, and it is easier to discharge first, to prevent the cement from sticking to the hopper, the sand is added to the cement, and the cement is sandwiched in the middle to prevent dust.
