Problems solved by technology

At present, the recycling rate of slag discharged from metal ore cleaning is not satisfactory, relying on storage and accumulation, filling pits, on the one hand, accumulation and filling pits occupy cultivated land, affect grain output, and reduce the cultivated area
On the other hand, when it rains, it is easy to flow into farmland and lakes with the rain, which will bring troubles to the surrounding farmers to cultivate. If it flows into ditches, ponds and lakes, it will also pollute water resources and turn green water into turbid water. To develop the environment and vigorously develop the metal mining industry, it is necessary to reasonably solve the flow direction of the slag, and to properly and rationally recycle the slag soil to convert it into valuable wealth, turn waste into treasure, and use it for the emerging social construction

Embodiment 1

[0020] 850 parts of slag, 150 parts of modified plasticizer, put into the crushing mixer, grind into powder and mix evenly, then add 1 part of reinforcing curing agent (solid content) depending on the humidity, add appropriate amount of water, put into the slag mixture, mix Evenly, transport it to the mold of the brick making machine, cut and shape it to make slag wall bricks, and dry it to get the finished product.

Embodiment 2

[0022] Put 900 parts of slag and 98 parts of modified plasticizer into the grinding mixer, grind them into powder and mix them evenly, then add 2 parts of solidification enhancer (solid content) and add appropriate amount of water depending on the dry humidity, and put them into the grinding machine Mix evenly, keep the humidity at about 80% dry, transport it to the pressure brick making machine for pressing and molding, and dry it to get the finished slag hollow core brick.

Embodiment 3

[0024] Put 940 parts of slag and 60 parts of modified plasticizer into the crushing mixer, grind them into powder and mix them evenly, then add 3 parts of solidification reinforcing agent (solid content) and add an appropriate amount of water, put them into the roller compactor, mix them evenly, Transport it to the brick making machine to cut and shape it, and dry it to get the finished slag wall brick.

Abstract

The invention provides a slag wall brick and a preparation method of the slag wall brick, and relates to a preparation process technology of the wall brick. Through mixing a modifying plasticizer and an enhancing curing agent with slag uniformly, compression resistant bricks are prepared through cutting with a brick making machine or hollow wall-filling blocks are prepared by compression molding. Due to the adoption of the method, the land source can be saved; the bricks are unfired, so that the energy is saved; the bricks can be manufactured easily and fast; the pollution and emission are avoided, so that the preparation method is environment-friendly; the compressive strength of the brick provided by the invention is higher than that of a sintered brick; the brick is water-proof, acid and base resistant and aging resistant; the utilization of was materials is realized, and the cost is low, so that the brick is the replacement of a traditional sintered brick, and is an effective measure for solving the slag accumulation problem.

Description

technical field [0001] The invention relates to a preparation technology of wall bricks, in particular to a slag wall brick and a preparation method thereof. Background technique [0002] With the mining expansion of the metal mining industry, the ore output is increasing, and the slag storage is also increasing. The increase in slag has brought difficulties to the development of the metal mining industry and plagued the rapid development of the mining industry. At present, the recycling rate of slag discharged from metal ore cleaning is not satisfactory. Relying on storage and accumulation and filling pits, on the one hand, accumulation and filling pits occupy cultivated land, affect grain output, and reduce the cultivated area. On the other hand, when it rains, it is easy to flow into farmland and lakes with the rain, which will bring troubles to the surrounding farmers to cultivate. If it flows into ditches, ponds and lakes, it will also pollute water resources and turn g...
