Wind Speed Of Ultrafine Vertical Mill

Posted by birder2525 on September 8th, 2022

In this case, when designing the ultrafine vertical mill, try to use a membrane-coated filter material with a smooth surface, no lint, and no fluff. in operation, an intermittent operation system should be adopted to minimize the area of ​​gas stagnation. in addition, in order to prevent dew condensation, if necessary, the method of heat preservation is adopted to increase the temperature of all processing gases.

The selection of filtration wind speed is related to factors such as cleaning method, filter cloth material, characteristics of flue gas and dust, etc. according to the actual use conditions of each ultrafine vertical mill in different occasions, it should be reasonably selected.

The dust concentration is different, and the filtering wind speed is also different. the higher the concentration, the smaller the filtering wind speed. such as general cement production industrial dust, the filtering wind speed is about 1-1.6m/min.

The length-diameter ratio of the filter bag also has an impact on the selection of the filtering wind speed. the larger the length-diameter ratio, the lower the filtering wind speed, so as not to cause the wind speed at the mouth of the bag to be too large and affect the life of the filter bag. therefore, in order to reduce the running resistance of the ultrafine vertical mill, the selection of a reasonable filtering wind speed is very important.
