1 Introduction

The transport of fine bulk solids, such as cement, raw meal, fly ash or coal, usually takes place pneumatically over complicated conveying line routes. This means that the bulk material is transported by conveying air through a pipeline system. The friction that occurs between the bulk material and the pipeline wall and the vertical lift in the bulk material conveying lines causes a loss of pressure in the conveying air. Consequently, the conveying air for the product transport must be made available at a plant-specific pressure. The bulk material has to be fed into the air flow...
