Abstract:Through the experimental research of granular silica in dense phase pneumatic conveying in the tyre plants, the characteristic parameters of granular silica pneumatic conveying have been obtained. By adjusting the main and bypass pipe pressure values, the stable plug flow conveying of granular silica can be realized, which considerably reduces the broken ratio of the granular silica. The plug flow conveying will be even more stable, when the opening blow tank pressure is set at zero. Additionally the same research has also proven that bypass valves open pressure in the end of pipeline will affect the stability of the entire conveying system as well.
