Problems solved by technology

[0002] In the existing aggregate production and processing technology of using engineering excavation stone slag to carry out hydraulic concrete, etc., when there is a gradation imbalance in the source of materials in each area, for example, some areas have more coarse materials and some areas have more fine materials. Some fixed and non-adjustable production processes will lead to an unbalanced gradation of finished aggregates, making it difficult to meet the needs of hydraulic construction concrete with many grades

Abstract

The invention discloses a processing technology and system for producing concrete aggregate by using a complex material source, and relates to the technical field of concrete aggregate production. Theprocess comprises the following steps: coarsely crushing excavated materials to form coarse crushed materials; intermediately crushing the coarse crushed materials to form intermediate crushed materials, screening the intermediate crushed materials, conveying the intermediate crushed materials of which the particle sizes meet a second particle size region to a finished product bin, and mixing theintermediate crushed materials of which the particle sizes meet a first particle size region with the coarse crushed materials; and finely crushing the coarse crushed materials and the intermediate crushed materials to form fine crushed materials, screening the fine crushed materials, mixing the fine crushed materials of which the particle sizes meet a first particle size interval with the coarsecrushed materials again for fine crushing, and conveying the fine crushed materials of which the particle sizes meet a second particle size interval to a finished product bin, wherein the first particle size interval is larger than the second particle size interval. According to the processing technology and system for producing concrete aggregate by utilizing a complex material source, the concrete aggregate can be produced by utilizing a complex excavated material source, and the processing technology and system have the characteristics of good aggregate shaping effect, continuous gradationof the produced finished aggregate and high material source utilization rate.

Description

technical field [0001] The invention relates to the technical field of producing concrete aggregates by using excavated materials, in particular to a processing technology and system for producing concrete aggregates by using complex material sources. Background technique [0002] In the existing aggregate production and processing technology of using engineering excavation stone slag to carry out hydraulic concrete, etc., when there is a gradation imbalance in the source of materials in each area, for example, some areas have more coarse materials and some areas have more fine materials. Some fixed and non-adjustable production processes will lead to an unbalanced gradation of the finished aggregate, making it difficult to meet the needs of hydraulic construction concrete with many grades. [0003] In view of this, it is particularly important to develop and design a processing technology and system for producing concrete aggregates using complex material sources that can s...
