Pneumatic transport of granular materials over plane using concentrated air flow

Abstract

The article provides the granular material pneu-matic transport by a plane. Since this process mainly de-pends on air flow velocity, which is formed by certain holes, a theoretical procedure is provided estimate the ini-tial velocity that is needed to inflate the transported mate-rial from the plane surface and by experiments it was con-firmed that the presented mathematical expressions of ma-terial transport by air flow are a realistic process. The suit-able opening of the holes at which the air flow velocity is at maximum has been determined by experiments. The developed mathematical equations were used to improve air flow for granular material transport and to obtain con-struction parameters of the required industrial equipment. The method will provide means to reduce the energy needs for this technological process.
