Experimental Study of Wear in Direct Lines of Pneumatic Conveying of Granular materials

Abstract Pneumatic conveying is a suitable way 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 was designed at the University of Tabriz. 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 among AA6063, SS 310, and SS 304 alloys. SS 410 has higher abrasion resistance. Higher conveying velocity has a significant effect on the wear rate. When the mass flow rate is increasing, the abrasion resistance of the conveying line is dependent on time. From the three granular particles, the abrasion behavior of wheat grain and barley are similar.
