Embodiment 1

[0016] Embodiment 1: as figure 1 Shown: an aggregate shaping technology, specifically realized by the combination of the following equipment: raw material → jaw crusher (1) → conveying device (2) → drum stone washing machine (3) → trommel screen (4) → return device (5) → main crushing equipment (6) → conveying device (2) → drum stone washing machine (3) → drum screen (4) → discharge device (7).

[0017] After the primary crushing treatment of the jaw crusher (1), the raw material becomes the material to be processed with a diameter not exceeding the upper limit, and is transported through the conveying device (2) into the drum stone washing machine (3) for stirring, grinding and cleaning with water. During the stirring process In the process, large pieces of material are continuously thrown up and down in the drum, and continuously collide with small pieces of material entering the drum, achieving a certain degree of "stone-on-stone" shaping and grinding effect. After a perio...

Abstract

The invention provides a concrete aggregate shaping method used for producing concrete aggregate with qualified grain shape. According to the concrete aggregate shaping method, an initial material is subjected to primary crushing so as to obtain a large-block material with a diameter equal to or smaller than an upper limit value; and the large-block material is processed via water-wash rotating stirring of a rollers stone scrubber and a rotary screen, wherein the large-block material is thrown up and falls down in rollers, and continuous collision grinding with small-block materials which are delivered into the rollers is realized, so that stone hit stone shaping grinding effect of the concrete aggregate is achieved.

Description

technical field [0001] The invention relates to a closed-circuit circulation shaping and crushing method for concrete aggregates, which is used for producing various ores, construction wastes, industrial solid wastes, etc. as raw materials. Background technique [0002] At present, with the development of my country's industry, the application of various concrete aggregates, especially recycled aggregates, is becoming more and more extensive, and various treatment process designs are gradually increasing. In the traditional crushing process, compared with natural stone, the recycled aggregate produced has more external edges and internal cracks, which is not conducive to guarantee Workability, durability and compressive strength of concrete. As a result, the utilization rate of renewable resources in ready-mixed concrete is low, and the strength and durability of recycled concrete have been hovering at a low level. Aggregates produced from waste concrete are used. Due to th...
