Hello, I'm trying to suit a pneumatic transport system for rubber particles from used tires. The size is about 0.2 mm. The mass flow comes from batches of 25 kg to be transported in 35 secs, that is around 2.6 metric tons per hour. The length is 8 meters horizontal and 12 meters vertical plus 2 curves and one cyclon. I've made the preliminary sketch with one fan that gives 1800 m3/h at 650 mmWg a rotary valve to introduce the material, tubing of 160 mm (around 25 m/s). The solid to air ratio is around 1.2.

I think that it would be enough, but somebody tell me that the rubber particles are very difficult to convey.

Do you think this system will work ??

Thanks in advance and best regards. ■
