The larger specific gravity of fine iron ore results in an increase of friction factor of densephaseconveying and has certain influence on various parameters.
铁矿粉的比重大使摩擦系数增大，对浓相输送时的各种参数有一定影响。

For densephaseconveying of pulverized material there is a close relationship among many parameters, such as fluidization velocity, carrier gas flow rate, pipe diameter etc.
结果表明，粉状物料的浓相输送与流化速度、补气量、输送管径有关。

Because of the PET chip yield reduce, in order to reduce the energy consumption, the PET chip conveying system was changed from densephaseconveying to dilute phase conveying.
