In the horizontal tee two branches pipe, pneumatic conveying experiment of hollow glass beading and millet was carried out using compressed air. The average diameters were both 2mm. The paper studied their resistance properties comparatively. The results showed: if the convey pressure was basically unchanged, for two kinds of particle which had the same average particle diameter but the different densities, when the openings difference value of the flow valve in the two branch pipes increased, in the region of higher gas velocity, the distance of the resistance properties curves became farther away, in the region of lower, curves were closer, the critical speed of branch pipe which had larger local resistance increased significantly, that of the other branch pipe declined slightly. The pressure drop value of particle with smaller density was smaller, the critical speed was generally higher, and the inflection point of the resistance characteristics curve appeared earlier.
