Dust resistivity is used for: electrostatic discharge control in silos and bulk material stacks, design of electrostatic dust collectors, selection of explosion-proof electrical equipment ,risk assessment of electrostatic accumulation.
Note: Electrical conductivity is the reciprocal of resistivity.
