Embodiment Construction
[0032] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0033] Such as Figure 1 to Figure 8 As shown, a process for making recycled aggregate from waste powder slag includes the following steps:
[0034] Step 1: Material collection: 380-385kg of 42.5 cement per cubic meter of recycled aggregate, 800-805kg of waste powder material, 1018-1025kg of waste gravel, and 40-45kg of water;
[0035] Step 2: Stirring: put each material obtained in step 1 into a mixing device, and stir each material into a bulk mixing material through the stirring device;
[0036] Step 3: Molding: Put the bulk mixing material obtained in step 2 into the molding equipment, and press the bulk mixing material into recycled aggregate through the molding equipment;
[0037] Step 4: Maintenance: Take out and store the recycled aggreg...

The invention discloses a process and forming equipment for manufacturing recycled aggregate from waste powder slag, and relates to the technical field of building materials. The process comprises the following steps of (1) materials taking, specifically, 380-385 kg of 42.5 cement, 800-805 kg of waste powder materials, 1,018-1,025 kg of waste rock ballast and 40-45 kg of water are selected for each cubic meter of recycled aggregate; (2) stirring, specifically, the materials obtained in the step (1) are put into stirring equipment, and the materials are stirred into a bulk mixed material through the stirring equipment; (3) molding, specifically, the bulk mixed material obtained in the step (2) is put into molding equipment, and the bulk mixed material is pressed into the recycled aggregate through the molding equipment; and (4) curing, specifically, the recycled aggregate prepared in the step (3) is taken out and stored, and curing is carried out for 28 days according to a curing scheme of a cement product. The molding equipment comprises a workbench, a mold assembly and a compaction assembly. According to the process, the recycled aggregate is manufactured from the waste powder materials and the slag materials, and can be used for manufacturing non-structural concrete members and concrete members with low strength requirements.
Description
technical field [0001] The invention relates to the technical field of building materials, in particular to a process and molding equipment for making recycled aggregates from waste powder slag. Background technique [0002] In the process of building construction, a large amount of waste powder materials and slag materials will be produced, but there are currently no related processes and related equipment that can deal with these waste powder materials and slag materials in large quantities, making these waste powder materials And slag materials will eventually be transported to the suburbs or around the city for simple landfill or open storage, which not only wastes land and resources, but also pollutes the environment. In addition, with the increasing population, the demand for recycled aggregates in the construction industry continues to grow. In addition, the existing methods of making recycled aggregates made of concrete are relatively simple, resulting in poor stren...
