Embodiment 1

[0014] The brick making process is:

[0015] (1) After shale and sandstone are mined, they are weathered for 3 days, and the sandstone, shale, and coal gangue are crushed to a fineness of 0.25 mm;

[0016] (2) Take arsenic sandstone, shale, coal gangue, coal powder and mix by weight, and its proportioning ratio is 20:70:10:0.25;

[0017] (3) Add 15 parts by weight of water in the mixture and stir;

[0018] (4) Stir the mixture into the brick making machine to extrude the mud strips to make bricks;

[0019] (5) The adobe is sintered in a kiln after drying. The sintering temperature is 950° C., the sintering time is 20 hours, and it leaves the kiln after 5 hours of heat preservation.

Embodiment 2

[0021] (1) After shale and sandstone mining, weathering for 5 days, crush sandstone, shale and coal gangue with a fineness of 0.20 mm;

[0022] (2) Take arsenic sandstone, shale, coal gangue, coal powder and mix by weight, and its proportioning ratio is 22:68:15:0.28;

[0023] (3) add the water stirring of 18 parts by weight in the mixture;

[0024] (4) Stir the mixture into the brick making machine to extrude the mud strips to make bricks;

[0025] (5) The adobe is sintered in a kiln after drying, the sintering temperature is 1000°C, the sintering time is 24 hours, and it leaves the kiln after 6 hours of heat preservation.

Embodiment 3

[0027] (1) Weathering 5 days after shale and sandstone mining, crushing sandstone, shale, and coal gangue to a fineness of 0.22 mm;

[0028] (2) Take arsenic sandstone, shale, coal gangue, coal powder and mix by weight, and its proportioning ratio is 25:65:12:0.3;

[0029] (3) Add 20 parts by weight of water in the mixture and stir;

[0030] (4) Stir the mixture into the brick making machine to extrude the mud strips to make bricks;

[0031] (5) The adobe is sintered in a kiln after drying. The sintering temperature is 1050° C., the sintering time is 22 hours, and it leaves the kiln after 5 hours of heat preservation.

[0032] The fineness of coal powder in each embodiment is below 0.4mm.

[0033] The sintered bricks produced in the above examples all have the characteristics of weathering resistance, alkali resistance, high strength and light weight.

Abstract

The invention discloses a method for manufacturing bricks by utilization of shale and sandstone, which comprises: mixing the shale, the sandstone, coal refuse and coal dust according to the ratio of 20-25:65-70:10-15:0.25-0.3 by weight portion; adding 15 to 20 weight portions of water into the mixture to be stirred and manufactured into green bricks; placing the green bricks into a kiln for sintering after drying the green bricks, wherein the sintering temperature is between 950 and 1,050 DEG C, and the sintering time is between 20 and 24 hours; and drawing the bricks out of the kiln after performing heat preservation for 5 to 6 hours. The sintered bricks have the advantages of weather resistance, alkali resistance, high strength and light weight. The method changes waste into valuable, saves farmlands, protects land resources, and has good social benefit and economic benefit.

Description

Technical field: [0001] The invention relates to a brick-making process, in particular to a brick-making process utilizing shale and arsenic sandstone. Background technique: [0002] The production process of clay solid bricks is a traditional brick-making process, but it often occupies or destroys farmland. In order to protect land resources, the country has already restricted the production of clay bricks. Therefore, various local resources have been used to develop different brick-making processes. Silt, coal gangue, iron tailings, etc. can be used as raw materials, and after a certain process, they are sintered to make bricks. Invention content: [0003] The object of the present invention is to provide a brick-making method for producing weathering-resistant, alkali-resistant, high-strength fired bricks by utilizing shale and plutonium sandstone. [0004] Technical scheme of the present invention is: [0005] (1) Pulverizing arsenic sandstone, shale, and coal gangue...
