Composite manufacturing device for preparing recycled aggregate from construction waste and recycled aggregate preparation method

Abstract

The invention relates to the technical field of construction waste regeneration, and discloses a method for preparing recycled aggregate from construction waste. A device comprises a shell, and further comprises two transverse rods which are respectively mounted between the left side wall and the right side wall of the interior of the shell and are arranged in parallel, crushing cutters are fixedly connected to the outer surfaces of the two transverse rods, and the left ends of the two transverse rods penetrate through and extend to the outer side of the shell and are fixedly connected with transmission gears, and the two transmission gears are meshed with each other; and the outer surface of the shell is fixedly connected with a first motor, and the output end of the first motor is fixedly connected with the left end of the transverse rod on the outer side. According to the manufacturing device for preparing the recycled aggregate from the construction waste, the waste is firstly crushed through the crushing cutters, then crushed through grinding of a grinding wheel and impacted by an impacting plate, the waste can be comprehensively crushed, aggregate particles are uniform, the particle size of the particles is small, the working requirement is met, repeated crushing is not needed, the working efficiency is high, and the working quality is good.

Description

technical field [0001] The invention relates to the technical field of construction waste recycling, in particular to a compound manufacturing device for preparing recycled aggregate from construction waste and a method for preparing recycled aggregate. Background technique [0002] Construction waste refers to the dregs, spoils, waste materials, residual mud and other wastes generated during the construction, laying or demolition and repair of various buildings, structures, pipe networks, etc. by construction, construction units or individuals. [0003] At present, the processing method of construction waste is to use jaw crushers for crushing, and the obtained aggregates are still in the form of larger blocks, which need to be crushed by other small crushers until the work requirements are met. However, the existing crushers are often Crushing is carried out by two relatively rotating knife rollers. Although the work efficiency is high, the aggregate obtained by crushing i...

[0003] At present, the processing method of construction waste is to use jaw crushers for crushing, and the obtained aggregates are still in the form of larger blocks, which need to be crushed by other small crushers until the work requirements are met. However, the existing crushers are often Crushing is carried out by two relatively rotating knife rollers. Although the work efficiency is high, the aggregate obtained by crushing is uneven, and the content of large particles in the crushed aggregate is high. It needs to be crushed repeatedly until it meets the work requirements, which is troublesome.
