Problems solved by technology

[0003] However, after the blocks are prepared, usually a small amount of blocks will be cracked or damaged
Because when recycling blocks, it is difficult to ensure that the blocks are prepared into fine particles, and it is difficult to recycle
In the past, such damaged bricks were often discarded directly, causing environmental pollution

Embodiment Construction

[0020] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0021] In the method for recovering blocks using a roller machine in the present invention, the processed blocks are screened, and the cracked or damaged blocks are first broken into fragments of about 5 cm by using a jaw crusher, and then passed through double rollers. The machine makes the fragments into powdered blocks with a size less than 1 cm, and finally replaces the sand with the powdered materials, mixes lime and water, and processes them into new blocks.

[0022] The double roller machine of the present invention comprises a first roller 1, a second roller 2, a feed hopper 3, a collection box 4, a scraper 5, and the bottom of the feed hopper 3 is arranged between the first roller 1 and the second roller 2 rollers, The collection box 4 is located at the bottom of the first roller 1 and the second roller 2 . The distance between the f...

Abstract

The invention relates to the field of recovery of waste building blocks, in particular to a double-roller machine and a method for recovering building blocks by the same. The method comprises steps as follows: cracked or damaged waste building blocks are crushed into pieces with the size about 5 cm by a jaw crusher; powdery building blocks which are 1 cm or smaller are prepared from the pieces by the double-roller machine; to-be-processed building block raw materials are prepared from lime and the building block powder in a weight ratio being 30:900-120:900 through mixing, finally, the to-be-processed building block raw materials and water are mixed in a ratio in percentage by weight being 100:5-100:20, and production of the building blocks is completed with a conventional building block production technology. Compared with a conventional grinding mode for grinding the building blocks into powder, the method has the characteristics of high processing speed, high processing efficiency, low cost and the like.

Description

technical field [0001] The invention relates to the field of recycling waste blocks, in particular to a double roller machine and a method for recycling blocks by using the roller machine. Background technique [0002] Blocks are artificial blocks made of concrete, industrial waste (slag, fly ash, etc.) or local materials. demands for institutional reform. The raw materials of the block include: lime, cement, fine sand, and phosphogypsum (waste from the local phosphate mine), tobacco ash (straw incineration), fly ash and other fine sand materials. After weighing the above materials, they are fed into Mixing station for mixing. During the manufacturing process, the blocks are originally relatively small, so that the quality of the blocks can be improved [0003] However, after the blocks are prepared, usually a small amount of blocks will be cracked or damaged. Because it is difficult to ensure that the blocks are prepared into fine particles when recycling the blocks, it...
