Shandong Shengya Machinery Co., Ltd. specializing in the production of various types of brick, brick machine, brick machine, hollow brick, pavement brick and other equipment of the old brick factory.
    Pulverized coal in suspension in the furnace combustion, coal in the vast majority of combustible can burn in the furnace, and pulverized fly ash in incombustible material (mainly ash) mixed in a large number of high-temperature flue gas. These incombustible material subjected to high temperature due to partial melting and, at the same time due to its surface tension, forming a large number of small spherical particles. In the rear of the boiler induced draft fan suction effect, containing a large amount of ash in the flue gas flow to the furnace end. With the decrease of the flue gas temperature, the molten portion by a certain degree of fine particles was quenched vitreous state, which has a higher potential activity. Before the induced draft fan in the flue gas into the atmosphere, these small spherical particles, after dust is separated, and collect the ash. Fly ash is one of the larger displacement of current industrial waste, the amount of slag at this stage in our country has reached 30 million t. With the development of power industry, coal-fired power plant fly ash emissions increased year by year, handling and utilization of fly ash attracted widespread attention.
Secondly, we must know the principles of brick form:
Billet gas is one of the main factors making brick layering. When pressed brick, the brick of the gas remaining in the wet mixture while air is compressed and becomes, once the pressing force is released, this part of the off-gas is compressed, is necessary to produce expansion, thereby destroying the internal structure of the brick. This residual amount of gas in the brick in larger gas expansion of destructive power more severe. The fly ash brick wet mix is ​​more of a three-phase system containing gas. When forming a large number of exhaust gas too late, so the gas remaining in the brick content than the first two brick are more stratification will more serious.
Fly ash brick wet mix all solid particles are powder, transfer of the pressing force is relatively slow, the material in the inner frictional resistance is large, and thus the pressing force attenuation when passing inside the brick is also large. So the use of fly ash brick pressing instantaneous way, is not easy to make uniform the weight and density of the brick. Also due to the need to use more fine-grained powder of water was added and the more moist lime and gypsum, in the wet mix manufacturing process, compared with the first two blocks of the wet mix to generate more gelling materials, although increasing the viscosity of the mixture, but it hinders the air removal from the molding of adobe smoothly. Residues brick in more air and more moisture will cause lower limit molding pressure.
