Embodiment 1

[0021] see Figure 1-4 , in an embodiment of the present invention, a construction waste fine crushing device includes a box body 1 and a crushing roller group 3; the upper end of the box body 1 is connected with a feeding hopper 2, and the construction waste is thrown into the box body from the feeding hopper 2 1; under the feeding hopper 2, there is a crushing and crushing roller group 3, which includes a set of crushing rollers arranged opposite to each other, and is used for preliminary crushing of construction waste for subsequent processing.

[0022] The box body 1 is provided with a grinding cylinder 4, the grinding cylinder 4 is a conical cylinder with an upper end open and set upside down, and evenly distributed sieve holes 5 are provided on the conical surface of the grinding cylinder 4, so as to facilitate the timely discharge of crushing materials that meet the crushing requirements. Garbage particles; the grinding cylinder 4 is nested with a grinding head 6, and t...

Embodiment 2

[0027] The difference between this embodiment and Embodiment 1 is that: the lower end of the grinding head 6 is fixedly connected with a rolling plate 7, and the lower end surface of the rolling plate 7 is provided with rolling teeth and arc-shaped convex corrugations, and the rolling plate 7 follows the grinding head. 6. Rotate downwards to crush and crush the construction waste accumulated at the bottom of the grinding cylinder 4. At the same time, the arc-shaped convex corrugations will move and screen the rolled particles to the outside to avoid accumulation of construction waste.

[0028] The lower end of the grinding cylinder 4 is fixedly connected with a support shaft 16, the support shaft 16 runs through the box body 1 and extends to the bottom of the box body 1, the support shaft 16 is connected to the base 17 through the bearing seat, and the support shaft 16 passes through the first transmission belt 18 is connected with transmission shaft 19, and transmission shaft ...

Abstract

The invention discloses a fine crushing device for construction waste. The fine crushing device for construction waste comprises a box body. A grinding drum is arranged in the box body, uniformly formed sieve pores are formed in a cone-shaped surface of the grinding drum, and a grinding head is embedded into the grinding drum. By arranging a grinding head capable of rotating up and down and the grinding drum provided with the sieve pores, preliminarily crushed construction waste is ground rotatably and screened. By arranging a grinding plate at the bottom of the grinding head, the constructionwaste accumulated at the bottom of the grinding drum is ground and crushed and pulled and screened outward. By arranging a supporting shaft, the grinding drum rotates to screen the construction waste, so that the screening efficiency is improved and the sieve pores are prevented from being blocked.

Description

technical field [0001] The invention relates to the field of construction waste treatment, in particular to a construction waste fine crushing device. Background technique [0002] Many wastes in construction waste can be reused as renewable resources after being sorted, removed or crushed. Among them, waste construction concrete and waste bricks are used to produce coarse and fine aggregates, which can be used to produce concrete and mortar with corresponding strength levels. Or prepare building materials such as blocks, wall panels, and floor tiles. Coarse and fine aggregates can also be used for road pavement bases after adding solidified materials; using waste bricks and tiles to produce aggregates can be used to produce recycled bricks, blocks, wall panels, floor bricks and other building materials; slag can be used for road construction, piles, etc. Base filler, foundation foundation, etc. [0003] The traditional construction waste crushing device has a poor crushin...
