Pneumatic conveying, is a suitable way to conveying of particles. It costs several dollars to equip pneumatic conveying systems. One of the main problems in the pneumatic conveying system is the wear of the conveying lines. The mechanism of wear experiment designed in the University of Tabriz. In this paper investigates the wear on conveying lines and how to reduce it. The results and analysis of the experiments showed that SS 410 is the best from AA6063, SS 310 and SS 304 alloys. SS 410 has higher abrasion resistance. Higher conveying velocity, it has a significant effect on the wear rate. When, mass flow rate is increasing, abrasion resistance of the conveying line is depending on to time. From the three granular particles, the abrasion behavior of wheat grain and barley are similar.
