Measuring apparatus and method for dusting graphite dust particles

The present invention provides an apparatus and method for dusting graphite dust particles measured. The apparatus comprises a high pressure gas injection systems, electrical heating piping system, primary system, dust and dusting test section of the pressure relief system. The device may study graphite dust from dust properties at high temperature and pressure, and may explore changes from before and after the dust particle size. Before air injected into the main circuit through the high pressure gas injection systems, via a conduit heating means to heat up, forming high temperature and pressure in the primary circuit. FM can flow through the fan constantly adjust the flow rate changes. Dust deposited on the graphite particles suspended in the center of the pipe, in a removable plate. Dusting obtained by measuring the share of the particles from the dust before and after the change in mass of the plate. Particle samples were collected from the front and rear plates dust for particle size analysis, particle size can be further characterized in different conditions of occurrence of dusting.
