Pneumatic conveying of abrasive products

The pneumatic conveying of abrasive materials, such as bands, feldspars, plastic granules loaded with fiberglass, and many others, presents significant challenges related to wear, especially in the curves of conveying path. To successfully address this issue, it is essential to adopt specific solutions that can ensure optimal handling of all involved components.

A key approach is low speed conveying combined with the use of anti-abrasion curves. Through dense phase pneumatic conveying, large quantity of material can be moved over long distances at low speed, eliminating or drastically reducing wear. This technology helps extend the lifespan of pipelines, curves, and thanks used in the conveying process. The addition of booster along the line offers further benefits by reducing the friction of the material on the inner walls of the pipes.

The curves are the points where wear occurs the most, and depending on the nature of the conveyed material, specific solutions need to be adopted. These range from the realisation of specific coatings or extrados, the use of thick cast iron or basalt bends, up to the development of curves with AI203 rings inside them.

Selecting the right pneumatic conveying technology and applying specific solutions not only improves process efficiency but also preserves the integrity and durability of the involved elements. In industries that use abrasive materials, choosing the right anti-abrasion strategies is crucial to ensure reliable and long-lasting pneumatic conveying.
