Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a fly ash fineness detection device. Background Art

[0002] In order to standardize the application of fly ash, it is very necessary to test the fineness of fly ash. Among the physical properties of fly ash, fineness and particle size are relatively important test items, which directly affect other properties of fly ash. The finer the fly ash, the greater the proportion of fly ash, and the greater its activity. The fineness of fly ash affects the early hydration reaction when mixed with concrete.

[0003] The patent name of the announcement number "CN218629410U" is: A fly ash fineness detection device. The device in the public document first discharges the coarse fly ash into the fly ash processing device for secondary processing by filtering. Because there is no filtering device in the fly ash processing device, the coarse fly ash cannot be temporarily retained in the fly ash processing device. At this time, the coarse fly ash will be directly discharged from the fly ash processing device through the pipeline into the lower end of the inner part of the screening machine, which will cause the gate knife to be unable to fully contact the coarse fly ash, affecting the effect of the gate knife on the secondary processing of the coarse fly ash. Based on this, the utility model designs a fly ash fineness detection device to solve the above problems. Utility Model Content
