Precipitation grinding ark dust density measurement of grinding ark true density that is not considered dust particle and particle spacing between the density of solid particles of itself. If particles itself is porous material, its density is divided into two kinds: a. Considering particle pore itself, particulate matter, under the condition of vacuum density have been measured, is called the true density; b。 Including particle pore itself the density of a single particle called the grain density. Usually measured by pycnometer method. For no pore particles, true density and particle density is the same. True density decided to dust particles of dust flow velocity of gas in the precipitator and pipeline. Dust polished tank packing density of dust particles and there are many gaps between the particles, the particle swarm natural accumulation is the quality of unit volume when packing density, ash hopper dust accumulation volume calculation method filter and store the size of ash storehouse with it because there are a lot of space between dust and dust, some particles and pore itself. Dust polished tank simulation under the condition of electrical dust catcher work dust deposition, and are measured under the conditions, namely the corona discharge under the action of the dust deposition on the disk, measured in dust layer on the voltage and the current through the dust layer, according to the geometric dimension calculation of the dust layer in the disk than the resistance of dust.
