The ball mill is acommonly used grinding equipment in a beneficiation plant. The productionefficiency of the ball mill directly affects the efficiency of the entirebeneficiation operation. With the development of the society and advances inscience and technology, more and more manufacturers are researching andexploring techniques for increasing the output of ball mills. It is also a needfor the gradual development of the beneficiation industry. The following arethe principles for the production of aluminum ash separation technology:
First, wheninstalling the aluminum ash ball mill, we must first integrate the automaticcontrol system so that it can be better operated. For example: According to thenoise of the ball mill, we use the electric ear method to control the electromagneticvibrating feeder or the belt feeder to control the grinding. The inner materialmakes the material evenly added, so that the amount of material in the mill isalways kept in an optimal state. This is the basic condition for improving theoutput of the ball mill.
Second, tomaintain the ventilation of aluminum ash ball mill in the best condition,because the mill has a certain speed, take away the powder generated during thegrinding process, reducing the buffer effect of the micronized powder, improvethe grinding efficiency and product quality. When the ventilation is good, thewater vapor in the mill is discharged in time, and the boring hole of thepartition board is not blocked, the adhesion phenomenon of the grinding body isreduced, and the temperature inside the grinding is reduced, which is favorablefor the operation of the mill and improving the quality of the product. Therate of ventilation in the mill varies with different materials, typically0.3-1.0 m/s. The production of high-strength grade cement should use low speed;otherwise it should use a bit more speed.
Third, if you wantto increase the output of the aluminum ash ball mill, the water in the millcannot be ignored. Inside the mill, the heat inside the mill can be effectivelyremoved, cooling inside the mill can be achieved, and the material on thegrinding body can be prevented from being contained. The water in the mill isdetermined according to the temperature inside the mill. Generally, no water issprayed below 1000°C. In addition, the amount of water spray according to thetemperature of the input clinker, about 1% -2% of the amount of cement, andcompletely sprayed into the mill water evaporation, no residual water. Watercan be sprayed from the grinding head or the tail water can be sprayed. When thetemperature of the incoming material is high, it is advantageous to spray waterfrom the grinding head, and in general the water is sprayed from the tail. Millwater spray can increase production capacity by 5%-10%.
Fourth, the lastis to add grinding aids in the aluminum ash ball mill, generally withtriethanolamine, and the blended amount accounts for 0.04%-0.1% of the milledmaterial, which can increase the production capacity by about 10%.
