Description

Technical Field

[0001] This utility model belongs to the field of concrete equipment technology and relates to a concrete mixing plant with a feeding system. Background Technology

[0002] Existing concrete mixing plants typically have independent square stone and sand silos on their roof supports for storing aggregates. While this increases the storage capacity to some extent, the placement of the material silos on the roof supports, along with the surrounding powder tanks adjacent to the stone and sand silos, limits the increase in their volume. This results in limited aggregate storage and difficulty in producing high-quality manufactured sand, leading to low concrete production efficiency and an inability to meet peak monthly concrete production demands. Conventional concrete mixing plants use stockpiled materials at the material yard, fed by a feeder in an underground corridor, and then conveyed into the mixing plant by a conveyor belt. This method is difficult to guarantee an effective supply of aggregates, and open-air stockpiling is environmentally unfriendly and pollutes the air. Therefore, it is imperative to find a concrete mixing plant with large storage capacity, high sand production rate, and excellent environmental performance. Utility Model Content
