Problems solved by technology

[0002] The traditional brick-making technology in our country is to use clay to sinter bricks, which requires a large amount of farmland mining, causing farmland damage, so many companies have begun to use other materials to replace or partially replace clay, such as fly ash or coal gangue in industrial waste, etc. , the development of the country's industry has led to a sharp increase in the discharge of industrial waste, which not only occupies a large amount of space, but also pollutes the environment. Brick enterprises began to use fly ash, coal gangue, etc. to produce sintered bricks. In addition, the rise of real estate not only required a large amount of construction waste during demolition, but also produced a large amount of earthwork when digging foundations. There are a lot of construction waste and earthwork Sometimes it is used to dump garbage dumps or river banks or riversides, occupying a large amount of land resources and destroying vegetation and river environments

Embodiment Construction

[0027] A kind of brick making method of the present invention, used raw material is coal gangue, building waste residue and building clay, is produced according to the following steps:

[0028] (1) The raw materials are crushed and ground into particles with a particle size of less than 1 mm. The mass percentages of coal gangue, construction waste residue and construction clay in the raw materials are: coal gangue: 20-30%, construction waste residue: 40-50%, construction waste residue: 30-40%, each of the above raw material components is loaded into the feeder through the loader, transported to the pulverizer through the feeder for pulverization, and the pulverized raw material particles are input into the powder rolling sieve through the belt conveyor for sieving. Coarse materials that can be sieved are sent to the pulverizer again through the belt conveyor for pulverization;

[0029] (2) Mix the raw material particles evenly, add warm water, naphthalene-based water reducer a...

Abstract

The invention discloses a brick making method which adopts coal gangue, building waste residues and building clay as raw materials and comprises the following steps: (1) grinding the raw materials into particles with particle sizes of less than 1mm; (2) uniformly mixing the raw material particles, adding warm water, a naphthalene water reducer and silica fume, stirring to prepare a mud material, and ageing for more than 24 hours; (3) stirring a mixture obtained after the ageing for 0.5-1 hour, and extruding the re-stirred mixture by adopting a vacuum brick extrusion machine to prepare green bricks; (4) putting the green bricks into a brick kiln, and intensively eliminating moisture and drying; (5) roasting by adopting a process of main internal combustion and auxiliary external combustion; (6) cooling to obtain finished bricks. According to the brick making method, the coal gangue, the building waste residues and the building clay are fully utilized as the brick making raw materials, farmland and land resources can be saved, plant covers and river environments are prevented from being destroyed, and produced floor tiles are good in plasticity and water permeability, relatively good in pressure bearing property, energy-saving and environmentally friendly.
