Red soil, sand, fly ash and water metering accuracy, to improve the quality of fly ash and unburned products remain homogeneous is quite important. Unburned cement mixer can be used the same blender.

    After screening by a qualified soil conveyor belt, halfway with raw fly ash (fineness of 160 mesh) and the measured particle size less than 2mm sand mixed into the concrete by hoist enter compulsory stir row machine, the first red loam , sand and fly ash dry mix for 2 minutes. The mix mixes, input conveyor belt digestion compartment. Digested in the digestive standing positions 4-5 hours, the material and the mixer input, a second stirring. The second purpose is to have a stirred mixture of digestion is completed to obtain a suitable molding material moisture. Out of position from the digestion mixture drier, not directly used to suppress the brick, because of poor moldability of the mixture, in the frictional resistance is large, the required pressure in the molding, the brick can not be compacted, it is necessary to mix A second material mixing with water to improve its formability. The second time mixing, add water not too much. After too much water may produce molding overvoltage phenomenon PRESS load will increase, and the brick surface will produce bleeding plasma phenomena in autoclave process is easy to produce blisters and cracks and other defects. Therefore, the second amount of water to be stirred in the range of optimal control of the water formed, when the molding pressure of 20 - 36MPa, the water content of the mixture of 10-17% suitable.

    Since the water content of the mixture after digestion is often changing, so after digestion according to the specific circumstances of the water content of the mixture, and regulating the amount of water in the second stirring.

    If the mixture is still a small amount of agglomeration after digestion, and the second should have crushed them stir the material caking effect.

     In short, the material measurement methods, there are manual and automatic calculation, but also a useful measure of the screw conveyor, but poor accuracy. The purpose is to stir the red loam uniformly mixed with fly ash, the strength of this brick is important. Concrete mixers generally used compulsory mixer, standing digest, so that the heat generated during the digestion of fly ash, is conducive to uniform and pre-reaction effect materials. If elimination of fly ash, you do not have to go through standing digestion, mixing well after, via intermediate storage system directly into PRESS blank. In this case, the use of fly ash elimination process, make bricks strength is low.
