Processing system of concrete combined aggregate and construction method

Abstract

The invention provides a concrete combined aggregate processing system, which comprises a first receiver bin. A first bar type feeder is disposed below the first receiver bin, the undersize part of the first bar type feeder is connected to a rejected material storage yard through a first adhesive tape machine, and the oversize part of the first bar type feeder is connected to a first jaw crusher. The discharge port of the first jaw crusher is connected to an artificial break stone storage yard through a second adhesive tape machine. A second bar type feeder is disposed below a second receiver bin. The oversize part of the second bar type feeder is connected to a second jaw crusher, and the undersize part of the second bar type feeder as well as the discharge port of the second jaw crusher is connected to a natural gravel storage yard through a third adhesive tape machine. The system provided in the invention can adopt two material sources at the same time to conduct production and processing, and the processed combined aggregate can satisfy the quality requirements of concrete aggregates, so that the work efficiency of the aggregate processing system can be enhanced. Moreover, the system is in favor of the sufficient use of project excavation ballast materials so as to reduce resource investment and project investment, and is also beneficial to environmental protection.

Description

technical field [0001] The invention belongs to a concrete composite aggregate processing system and a processing method thereof. Background technique [0002] Restricted by existing technical conditions, a concrete aggregate processing system can only use one material source for aggregate processing at the same time. If two different sources of materials are used for processing with one aggregate processing system, either two sources of materials are used for processing in stages with one aggregate processing system; or two aggregate processing systems are constructed to use two sources of materials for processing Aggregate processing. [0003] If two kinds of material sources are used for staged processing, it is not conducive to the interlayer bonding of concrete structures, nor is it conducive to the grading adjustment of the aggregate processing system, and the production capacity of the system is restricted by the gradation of material sources. If two aggregate proce...

[0003] If two material sources are used for phased processing, it is not conducive to the interlayer bonding of concrete structures, nor is it conducive to the grading adjustment of the aggregate processing system, and the production capacity of the system is restricted by the gradation of material sources.

If two aggregate processing systems are used to process aggregates from two different sources, it will not only increase the investment in project construction, but also increase the land occupation of the project. At the same time, it is not conducive to the gradation adjustment of the aggregate processing system, and will lead to the loss of concrete. The increase in the number of mix specifications and the frequency of concrete production test inspections will increase resource investment, thereby increasing project operation and management costs
