Material wear and equipment degradation

Building on the information presented in his first three series of columns, Paul E. Solt -- a private consultant with more than 40 years experience installing and troubleshooting pneumatic conveying systems -- presents a fourth series of columns on troubleshooting pneumatic conveying systems. In a separate section, Solt also answers your pneumatic conveying questions.

We'll consider these topics together because their causes and corrections are similar.

Equipment wear occurs when a hard, abrasive particle hits the conveying line and associated equipment.
