Preventing and solving some common pneumatic conveying problems

If your pneumatic conveying system has problems -- such as being unable to convey multiple materials at the desired capacity, degrading your material, or creating safety hazards -- the cause is probably a flawed system design. This article's first section details how you can prevent such problems by running conveying tests on your materials during the system design process. The remaining sections explain how you can diagnose and solve problems in a poorly designed existing pneumatic conveying system.

Designing a pneumatic conveying system that effectively conveys your material and operates without problems requires accurately understanding your application and, in particular, knowing your material's conveying properties. These conveying properties depend primarily on the material's physical characteristics, including particle size and shape, bulk density, softness or hardness, elasticity, temperature sensitivity, moisture sensitivity, and permeability.
