Gradation and the foundation for calculating sand factor；The quality and density for usually requiring measurement accumulation bulk granular material, could obtain material
Voidage, but the measurement of quality of material need to be measured by container, and measurement method is relatively complicated, and human factor is more, influences
Measurement result；And if the measurement of apparent density encounters scleroid bulk granular material, such as sand, stone, need to wear into fine powder measurement
Its apparent density, time-consuming, effort generally measure its density approximation instead of its apparent density in application process, cause larger mistake
Difference.It is therefore proposed that a kind of realization device of determining accumulation bulk granular material voidage, may be implemented to be precisely calculated accumulation and dissipates
The voidage of granular material, and be generalized to apply in various industries and be of great significance.
[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of dress of determining accumulation bulk granular material voidage
It sets, is able to solve the prior art there are measurement methods relatively complicated, time-consuming, effort, human factor is more, be easy to cause larger mistake
Difference influences the problems such as measurement result.
The utility model is realized in this way:
A kind of device of determining accumulation bulk granular material voidage, described device includes: fixed frame, laser measuring apparatus, biography
