Dust Layer Minimum Ignition Temperature Tester
The Dust Layer Minimum Ignition Temperature Tester is a specialized instrument used to determine the minimum temperature of a hot surface at which a dust layer of specified thickness ignites when deposited on that surface.
Application
This instrument is mainly used for dust explosion hazard assessment in production and processing environments involving aluminum powder, zinc powder, plastic powders, intermediates of organic synthetic pharmaceuticals, wheat flour, sugar, wood dust, dyes, bakelite ash, milk powder, tea powder, tobacco dust, coal dust, plant fiber dust, and similar materials. It enables accurate determination of the minimum ignition temperature of dust in a deposited (layered) state. Test
