AI Technical Summary
Existing fine aggregate concrete production equipment has high aggregate bulk density and significant inter-particle interference during continuous feeding, making it difficult for airflow to penetrate evenly, resulting in low grading efficiency and a decrease in the target grade mix ratio.
An air classifier combined with a vibrating screen assembly is used. The intermittent batch feeding of the material is controlled by a drive motor through the feeding pipe. Combined with the screening of the vibrating screen and the processing of the crusher, the material is conveyed and screened in batches, preventing excessive feeding at one time and reducing the classification load.
It improves grading efficiency, ensures uniform particle size distribution, increases the pass rate of target gradation, and meets the demand of fine stone concrete for high-performance aggregates.
