Solids Processing Understanding Bends R B

Historically, a basic long-radius bend (shown in Figures 1 and 2, and discussed below) has been the bend of choice for de-signers of pneumatic conveying systems, for a variety of reasons: • Long-radius bends Backgroundprovide the most gradual change in direction for solids, and hence are most similar to a straight section of piping

2.2. Methods. Air and solids were fed into the pneumatic conveying system through the inlet at the horizontal conveying section. The solids were conveyed up the vertical test pipe through the 90 ∘ bend and are subsequently collected in the filter tank. The experiments were conducted for conveying of polypropylene beads with solids mass loading (G s) of 15.8, 31.1 and 46.3 kg m-2 s-1.

Pneumatic Conveying and Materials Handling Advantages …

Pneumatic Conveying and Materials Handling Benefits of the Rhino Bends. Prior to the development of Rhino Bend, many pneumatic conveying systems experienced extremely high resistance across bends; thus dramatically reducing the efficiency of the system. Moreover, the speeds at which these materials were conveyed often caused the bends to wear through prematurely.

Introduction to Pneumatic Conveying of Solids

What is pneumatic conveying? Pneumatic conveying is the movement of solids through pipe using gas (usually air) as the motive force. It differs from hydraulic or slurry conveying in that the gas expands continuously along the pipe length. The flow regime in the pipe depends greatly on the ratio of solids to gas and the particle characteristics.
