Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] refer to figure 1 The recycling method of waste concrete mixture of the present invention shown, method step comprises:

[0033] 1) Classify and clean the waste concrete mixture;

[0034] 2) Crushing the cleaned waste concrete mixture;

[0035] 3) Shaping the broken waste concrete mixture to make spherical coarse aggregate and fine aggregate;

[0036] 4) Dry the powder produced when crushing and shaping the waste concrete mixture, and then grind it;

[0037] 5) The waste concrete mixture treatment and concrete are jointly produced in the same mixing station.

[0038]In the embodiment, the broken waste concrete mixture is reshaped by using a vertical mill to finely grind the broken waste concrete mixture, and then using a tube mill for fine grinding to form a double mill series structure. For application, batching can be carried out according to th...

Abstract

The invention relates to a method for recycling waste concrete mixture. The method comprises the following steps: 1) classifying and cleaning the waste concrete mixture; 2) crushing the cleaned wasteconcrete mixture; 3) shaping the crushed waste concrete mixture to form globoid coarse aggregate and fine aggregate; 4) drying and grinding powder generated in the crushing and shaping process of thewaste concrete mixture; and 5) performing waste concrete mixture treatment and concrete production in the same mixing station. The method is combined with the concrete mixing station to combine premixed concrete and waste concrete mixture production, so the intermediate transportation link is reduced, energy is saved, leakage and dust flying in the intermediate link are reduced, multiple purposesof one machine, using local materials and adaptation to local conditions are achieved, a multi-mineral admixture can be processed, device values are maximized, the investment is reduced, and the occupied area is reduced.

Description

technical field [0001] The invention relates to the technical field of recycling of construction waste, in particular to a method for recycling waste concrete mixture. Background technique [0002] Concrete is the largest building material used by human beings, and its theory and technology have become increasingly mature. However, when a large amount of concrete is used, it has a negative impact on the living environment and ecological system. Urban demolition and engineering transformation also discard a large amount of concrete. The disposal of waste concrete wastes a lot of land resources and pollutes the environment. In response to this drawback, recycled concrete is widely used in foundation reinforcement and road engineering, but the status quo of waste concrete reuse and some existing problems. [0003] At present, with the rapid development of my country's economy, urban public and civil buildings and municipal facilities are undergoing a large number of renewal an...
