Description

[0001] The utility model relates to the technical field of fly ash sintered brick production, and particularly relates to a raw material mixing device for fly ash sintered brick production and processing. BACKGROUND

[0002] The raw material processing flow in fly ash sintered brick production covers key steps such as open-air weathering, raw material crushing, mixing and aging treatment, and wet rolling. Specifically, the open-air weathering process selects "last year's soil" that has undergone a weathering period of 1.5 to 2 years to ensure the performance of the cementing material. After being directly fed into the plate feeder by the loader, the raw material is finely crushed by the jaw crusher and hammer crusher in turn through the secondary crushing technology. In the raw material mixing and aging stage, the finely crushed cementing material is accurately metered by the sealed belt conveyor and delivered to the box feeder, while the fly ash is metered by another box feeder by the bulldozer. After the two materials are mixed by the aggregate belt conveyor, they are sent to the mixing equipment for uniform mixing with water. Then, the mixed materials are transported to the aging warehouse for aging treatment by the belt conveyor and reversible warehouse belt conveyor. The wet rolling stage uses a wet wheel roller (i.e., a double-shaft mixer) and a high-speed fine crushing roller to implement the final treatment of the mixed materials.
