Method for increasing mixing amount of mineral powder in cement for road
The invention discloses a method for increasing the mixing amount of mineral powder in cement for a road. The method comprises the following steps: regulating the grade of a grinding machine, namely arranging an activation flow limiting ring in a fine grinding bin so as to realize grinding, flow control and material lifting; regulating the grading of a grinding body in the grinding machine according to the varieties of materials and cement; regulating comprehensive material parameters, namely regulating the technical parameters including the size of a screening device, ventilation in the grinding machine and the rotating speed of the grinding machine, and optimizing the powder selection efficiency of the grinding machine; periodically calibrating and checking a dosing scale; enhancing the strength of clinker; regulating the mixing amount of slag of a granulation blast furnace so that the contents in percentage by weight of the slag of the granulation blast furnace, gypsum and the clinkers are as follows: the slag of the granulation blast furnace is 8.0 percent, gypsum is 4.9 percent and the clinker is 87.1 percent. The method for increasing the mixing amount of the mineral powder in cement for the road can be used for overcoming the defects in the prior art that the grading of the grinding machine is unreasonable, metering accuracy is poor and the clinker strength is low, so as to achieve the advantages of reasonable grading of the grinding machine, good metering accuracy and high clinker strength.
