· Pneumatic conveying pertains to the transport of solid particulates with moving carrier gas (typically air). The drag force generated by the slippage between the gas and the particles (or ensemble of particles, such as a packed bed) overcomes the frictional losses and gravitational force, providing the necessary energy to move the particles
